Answer:

6.375 cups of raisins

Step-by-step explanation:

The ratio of raisins to peanuts is 3:2. This is because 0.5 divided by 2 and then multiplied by 3 is equal to 0.75.

So to find the number of raisins we need to divide the number of peanuts by 2 and then multiply it by 3:

(4.25 ÷ 2) × 3 = 6.375

Step-by-step explanation:

The larger number is 66 and the smaller number is 14.

Step-by-step explanation:

Let,

The larger number = x

The smaller number = y

According to given statement;

x-y=52     Eqn 1

5y = x+4   Eqn 2

From Eqn 2

x = 5y-4    Eqn 3

Putting value of x from Eqn 3 in Eqn 1

[tex]5y-4-y=52\\4y=52+4\\4y=56[/tex]

Dividing both sides by 4

[tex]\frac{4y}{4}=\frac{56}{4}\\y=14[/tex]

Putting y=14 in Eqn 3

[tex]x=5(14)-4\\x=70-4\\x=66[/tex]

The larger number is 66 and the smaller number is 14.

This is a disguised GCF problem. If Jacqueline wants to use all the flowers she has, she must find the greatest common factor of the their numbers.

1. Determine the prime factors of each number and mark those that are common

The prime factors of 42 are 2        × 3             × 7  = 42

The prime factors of 36 are 2 × 2  × 3 × 3 × 3       = 36

The prime factors of 54 are 2        × 3 × 3 × 3        = 54

2. Multiply the common factors

The common prime factors of 42, 36. and 54 are 2 and 3.

The greatest common factor is 2 × 3 = 6.

(x + 1)(x + 8)

Step-by-step explanation:

Given

x² + 9x + 8

Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (+ 9)

The factors are + 1 and + 8, since

1 × 8 = 8 and 1 + 8 = 9, thus

x² + 9x + 8 = (x + 1)(x + 8)

Answer:

ur numbers are 2 and -5

Step-by-step explanation:

7x + 3y = -1

x + y = -3......x = -3 - y

7(-3 - y) + 3y = -1

-21 - 7y + 3y = -1

-7y + 3y = - 1 + 21

-4y = 20

y = -20/4

y = -5 <====

x = -3 - y

x = -3 - (-5)

x = -3 + 5

x = 2 <====

Answer: The numbers are 2 and -5

Step-by-step explanation:

7x+3y=-1  ...(equation 1)

x+y=-3    ...(equation 2)

x+y=-3

Broken down, we have x=-3-y

Substitute x=-3-y into equation 1

Then we have 7(-3-y) +3y=-1

Which is -21-7y+3y=-1

which is -21-4y=-1

-4y=-1+21=20

y=-20/4=-5

y=-5

Substitute y=-5 into equation 1  

x+y=-3

x-5=-3

x=-3+5=2

x=2

Answer:

y=-5x+1

Step-by-step explanation:

y-y1=m(x-x1)

y-(-9)=-5(x-2)

y+9=-5x+10

y=-5x+10-9

y=-5x+1

The linear equation that passes through the point (2, -9) with a slope of -5 is y = -5x + 1.

To find the linear equation, we use the point-slope form of a line, which is:

y - y₁ = m(x - x₁)

Here,

m is the slope and (x₁, y₁) is a point on the line.

Given:

Substitute the values into the point-slope form equation:

y - (-9) = -5(x - 2)

Simplify the equation:

So, the linear equation in slope-intercept form is y = -5x + 1.

Step-by-step explanation:

The area of a parallelogram is A=bh.

From the diagram, the base is b=5m

We now use the properties of 30°-60°-90° right angle to find h.

The sides of this triangle is given by x,½x,½x√3

Where x is 4

Therefore we have 4,2, 2√3

So we have h=2√3m

Answer:

8/27 is already in the simplest form. It can be written as 0.296296 in decimal form (rounded to 6 decimal places).

Answer: If it is on a coordinate plane, (-1,-4) would be in quadrant 3. (1,4) would be in quadrant one.

Step-by-step explanation:

quadrant 1 is both positive numbers (both the x and the y axis).

quadrant 2 is when the x axis is negative and the y axis is positive.

quadrant 3 is when both the x and y axis is negative

quadrant 4 is when the x axis is positive and the y axis is negative.

Answer:

First Problem:  $50.15

Second Problem:  $20,468

Step-by-step explanation:

First Problem:  If the original price is $41.00 and the discount is $6.15

41.00 - 6.15 = $34.85 is the discounted price

34.85 / 41.00 = 0.85 -> this shows the amount that you pay from the original price

So if the other product costs $59.00 you just do 59.00 * 0.85 = $50.15

This shows that %85 of the original cost is what you pay.

Second Problem:  So, the first amount sold is 160 tickets and the price for each ticket is $59.50.

160 * $59.50 = $9,520 for the afternoon batch

If they sold %15 more in the evening that means that they sold 160 tickets plus another %15 of the 160.

160 * 1.15 = 184 tickets sold in the evening

184 * $59.50 = $10,948 for the evening batch

So they sold a total of $9,520 + $10,948 = $20,468

Answer:

44)  $50.15

45) $20,468

Step-by-step explanation:

44)  $ off sweater = 6.15

41.00 - 6.15 = 34.85

6.15 ÷ 41.00 = 0.15 = 15% discount

$59.00 - 15%

$50.15

45)

Afternoon = 160 tickets

Evening = 15% more = 160 + 15% = 184 tickets

160 + 184 = 344 tickets total

344 * $59.50 = $20,468

Hope this helps :)

Answer:

x=10

Step-by-step explanation:

First combine like terms:

14x + 40 = 180

Second subtract 40 from both sides:

14x = 140

Third divide both sides by 14:

x = 10

After simplifying the expression 2(3a-2)+4a, we get 10a-4, which is not equivalent to 10a-2 due to a difference of 2.

To determine if the expression 2(3a-2)+4a is equivalent to 10a-2, we must simplify the former expression.

First, distribute the 2 into the parenthesis: 2 × 3a is 6a, and 2 × -2 is -4. So we get 6a - 4.

Next, we add the 4a that is outside the parenthesis to the 6a we got after distribution: 6a + 4a equals 10a.

Now we have 10a - 4. This is close to 10a-2 but there is a difference of 2. Therefore, the two expressions are not equivalent.
