Makoto's summer job is mowing and edging lawns. He charges $20 to mow a lawn and $10 to edge a lawn. Makoto earned $180 mowing some lawns and edging 4 lawns. How many lawns did he mow?
Answers
Answer:
7
Step-by-step explanation:
to edge a lawn =10.he edged 4 lawn =10multiplied by 4=40
2nd. total -40=180-40=140
3rd. when he mows 1 lawn he is paid 20 what about when he is paid 140=140 divided by 20 =7
Makoto mowed 7 lawns to earn $180.
Let's denote the number of lawns Makoto mowed as m. Since he edged 4 lawns, that part of the income is 4 times $10, which sums up to $40. The total income from mowing is then $20 times the number of lawns he mowed, which is m. The equation representing Makoto's earnings is:
20m + 40 = 180
Subtracting 40 from both sides gives us:
20m = 140
Dividing both sides by 20 to solve for m gives us:
m = 7
3 Fred is making a fruit salad. The ratio
of cups of peaches to cups of cherries
is 2 to 3. How many cups of peaches
will Fred need to make 60 cups of
fruit salad?
Answers
Answer: 24 cups.
Step-by-step explanation:
Let be "x" the amount of cups of peaches that Fred will need to make 60 cups of fruit salad.
According to the information given in the exercise, you know that the ratio of cups of peaches to cups of cherries is the one shown below:
[tex]2:3[/tex]
Which can also be written as a fraction:
[tex]\frac{2}{3}[/tex]
Then, if he uses 2 cups of peaches and 3 cups of cherries, he will get 5 cups of fruit salad.
Knowing the above, you can set up the following proportion:
[tex]\frac{2}{5}=\frac{x}{60}[/tex]
Now you must solve for "x" in order to find its value. This is:
[tex](60)(\frac{2}{5})=x\\\\x=24[/tex]
Jorge is setting up his tent. He is using two nylon ropes to pull the tent taut and stabilize it at each end.

PLEASE HELP ME !!!!!!!!!!
Answers
Answer: 5.8 ft
Step-by-step explanation:
We can use the Pithagorean Theorem in this problem, in order to find the length of the rope:
[tex]h^{2}=a^{2}+b^{2}[/tex]
Where:
[tex]h[/tex] is the length of the rope (the hypotenuse of the right triangle formed by the height of the tent, the rope and the ground)
[tex]a=5 ft[/tex] is the height of the tent (one of the legs of the right triangle)
[tex]b=3 ft[/tex] is the other leg of the right triangle
Solving the equation with the given data:
[tex]h^{2}=5^{2}+3^{2}[/tex]
Finding [tex]h[/tex]:
[tex]h=\sqrt{(5 ft)^{2}+(3 ft)^{2}}[/tex]
[tex]h=\sqrt{25 ft+9 ft}[/tex]
[tex]h=5.83 ft \approx 5.8 ft[/tex] This is the total length of nylon rope

v > -1
Step-by-step explanation:
1/3(v-2) < v
Multiply both sides by 3(from 1/3) to equalize both sides.
This is equal to:
v-2 < 3v
Simplify equation:
v-2 < 3v =
-2 < 3v - v =
-2 < 2v
-1 < v
Swap sides:
v > -1
Therefore v is greater than -1.
Answer:
v > -1
Step-by-step explanation:
Simplify the left side.
Apply the distributive property.
13v+13⋅−2<v
Combine 13 and v
v3+13⋅−2<v
Combine 13 and −2
v3+−23<v
Move the negative in front of the fraction.
v3−23<v
Move all terms containing v to the left side of the inequality.
Subtract v from both sides of the inequality.
v3−23−v<0
Simplify the left side of the inequality.
−2(v+1)3<0
Multiply each term in −2(v+1)3<0 by −1
2(v+1)3>0
Multiply both sides of the equation by 3
2(v+1)>0⋅(3)
and again Simplify the left side.
Apply the distributive property.
2v+2⋅1>0⋅(3)
Multiply 2 by 1
2v+2>0⋅(3)
Multiply 0 by 3
2v+2>0
Subtract 2 from both sides of the inequality.
2v>−2
Divide each term by 2 and simplify.
Getting the conclusion where V is greater than 1
v>−1

evaluate the following 7 = 5x+y÷3-3y
Answers
Answer:
5x + 22y = 21
or
5x + 22y - 21 = 0
Step-by-step explanation:
evaluate 7 = 5x+y÷3-3y
7 = [5x + y]/[3-3y]
Don't forget 7 can also be expressed in form 7/1,
so the step to follow is using a cross multiplication technique.
we have ;
5x + y = 7(3 - 3y)
5x + y = 21 - 21y
Collect the like terms (note when the negative sign crosses over the equal to sign it changes to positive and the same thing applies to positive sign it changes to negative respectively.)
5x + y + 21y = 21
5x + 22y = 21
5x + 22y - 21 = 0

What is an equation of a line which passes through (6,9) and is perpendicular to the line whose equation is 4x − 6y = 15?

1) y−9=−2(x−6)
2
2) y−9= 3(x−6)
3
3) y+9=−2(x+6)
4) y+9=23(x+6)
Answers
Given:
The equation of the line passes through the point (6,9) and is perpendicular to the line whose equation is [tex]4 x-6 y=15[/tex]
We need to determine the equation of the line.
Slope:
Let us convert the equation to slope - intercept form.
[tex]-6 y=15-4x[/tex]
[tex]y=\frac{2}{3}x-\frac{5}{2}[/tex]
From the above equation, the slope is [tex]m_1=\frac{2}{3}[/tex]
Since, the lines are perpendicular, the slope of the line can be determined using the formula,
[tex]m_1 \cdot m_2=-1[/tex]
[tex]\frac{2}{3} \cdot m_2=-1[/tex]
[tex]m_2=-\frac{3}{2}[/tex]
Therefore, the slope of the equation is [tex]m=-\frac{3}{2}[/tex]
Equation of the line:
The equation of the line can be determined using the formula,
[tex]y-y_1=m(x-x_1)[/tex]
Substituting the point (6,9) and the slope [tex]m=-\frac{3}{2}[/tex] in the above formula, we get;
[tex]y-9=-\frac{3}{2}(x-6)[/tex]
Simplifying the terms, we get;
[tex]2(y-9)=-3(x-6)[/tex]
[tex]2y-18=-3x+18[/tex]
[tex]3x+2y=36[/tex]
Thus, the equation of the line is [tex]3x+2y=36[/tex]
The equation of a line that is perpendicular to the line 4x - 6y = 15 and passes through the point (6,9) is 3x + 2y = 36. This is because the slope of the new line is the negative reciprocal of the slope of the given line, and the line passes through the given point (6,9).
Explanation:The subject of this question is mathematics, specifically in the topic of linear equations. To find the equation of a line that is perpendicular to a given line and passes through a certain point, we first need to find the slope of the given line. The standard form of the equation of a line is Ax + By = C. The given line is 4x - 6y = 15. We can find its slope by taking the negative reciprocal of the coefficient of x (A) over the coefficient of y (B), so the slope of the given line is -4/-6 = 2/3. Since we want a line that is perpendicular to the given line, the slope of the line we are looking for would be the negative reciprocal of the slope of the given line, which would be -3/2, because perpendicular lines have slopes that are negative reciprocals of each other. Using the point-slope form of a line, y - y1 = m(x - x1), where m is the slope and (x1, y1) is the given point, the equation of the line we are looking for is y - 9 = -3/2(x - 6), which simplifies to 2y - 18 = -3x + 18 and further simplifies to 3x + 2y = 36. So the answer is none of the given options.

The length of a rectangle is 2 units more than the width. The area of the rectangle is 48 units. What is the width, in units, of the rectangle?
Answers
Final answer:
To find the width of a rectangle when the length is 2 units more than the width and the area is known to be 48 units, you can use algebraic equations to determine the width. In this case, the width of the rectangle is 6 units.
Explanation:
To find the width of the rectangle:
Let x be the width of the rectangle.
Since the length is 2 units more than the width, the length is x + 2.
Given that the area is 48 units, use the formula for the area of a rectangle: width x length = area. Therefore, x(x + 2) = 48.
Solve for x by setting up the equation: x^2 + 2x - 48 = 0.
Factor the quadratic equation: (x + 8)(x - 6) = 0.
Since the width cannot be negative, the width of the rectangle is 6 units.
The width of the rectangle is 6 units.
According to the question, the length is 2 units more than the width, so we can express the length as ( w + 2 ) units.
The area of a rectangle is given by the product of its length and width. Therefore, we can set up the following equation to represent the area of the rectangle:
[tex]\[ \text{Area} = \text{length} \times \text{width} \] \[ 48 = (w + 2) \times w \][/tex]
Expanding the right side of the equation, we get:
[tex]\[ 48 = w^2 + 2w \][/tex]
To find the value of w, we need to solve the quadratic equation. Let's rearrange the equation to set it equal to zero:
[tex]\[ w^2 + 2w - 48 = 0 \][/tex]
Now, we can factor this quadratic equation:
[tex]\[ (w + 8)(w - 6) = 0 \][/tex]
Setting each factor equal to zero gives us two possible solutions for w:
[tex]\[ w + 8 = 0 \quad \text{or} \quad w - 6 = 0 \][/tex]
Solving for w, we get:
[tex]\[ w = -8 \quad \text{or} \quad w = 6 \][/tex]
Since the width of a rectangle cannot be negative, we discard the negative solution. Therefore, the width of the rectangle is:
[tex]\[ w = 6 \text{ units} \][/tex]
On Saturday, local hamburger shop sold a combined total of 450 hamburgers and cheeseburgers. The number of cheeseburgers old was two times the number of hamburger sold. How many hamburgers were sold on Saturday?
Answers
Answer:
There was 150 hamburgers sold on Saturday
Step-by-step explanation:
Step 1: Make an equation
2x + x = 450
Step 2: Solve for x
2x + x = 450
3x / 3 = 450 / 3
x = 150
Answer: There was 150 hamburgers sold on Saturday
Final answer:
The local hamburger shop sold 150 hamburgers on Saturday. This was found by setting up a system of equations where H represents hamburgers and C represents cheeseburgers, and solving for H.
Explanation:
To determine how many hamburgers were sold on Saturday, we can set up a system of equations based on the information given:
Let H represent the number of hamburgers sold.
Let C represent the number of cheeseburgers sold.
We are told that the total number of hamburgers and cheeseburgers sold is 450, so:
H + C = 450
We also know that the number of cheeseburgers sold was two times the number of hamburgers sold, so:
C = 2H
Now we substitute the second equation into the first one to solve for H:
H + 2H = 450
3H = 450
H = 450 / 3
H = 150
Therefore, on Saturday, the local hamburger shop sold 150 hamburgers.

Which property is demonstrated in the equation 4×7×3 = 7×4×3
A)Symmetric
B)associative
C)property of zero
D)cummutative
Answers
Answer:
B) associative
Step-by-step explanation:
The associative property of multiplication says you can choose which pair of numbers to multiply first, so when every operation is multiplication, you can move parentheses without changing the answer.
The given equation 4×7×3 = 7×4×3 demonstrates the Commutative Property. This is the property which states that the order in which numbers are multiplied or added does not affect the result.
Explanation:The equation 4×7×3 = 7×4×3 demonstrates the Commutative Property. In mathematics, the Commutative Property refers to the fact that the order in which numbers are multiplied does not change the result of the multiplication. This is why we can rearrange the factors 4, 7, and 3 in any order and still get the same product.
For instance, we can express the commutative property of multiplication as a×b = b×a. So, in your example, the equation 4×7×3 = 7×4×3, is an application of this principle as you are simply rearranging the order of numbers being multiplied.
Please remember that this rule applies only to addition and multiplication, not subtraction or division.

Answers
The range of the data set is 67 pounds.
Explanation:The range of a data set is the difference between the maximum and minimum values. In this case, the weights of the 7 dogs are 66, 8, 12, 74, 36, 66, and 7 pounds. To find the range, we subtract the smallest value (7) from the largest value (74):
Range = 74 - 7 = 67
So, the range of the data set is 67 pounds.
