7(y + 2) – (4y – 10) = 44 – 2y + 5
Answer:
y = 5
Step-by-step explanation:
7(y + 2) – (4y – 10) = 44 – 2y + 5
(7y+14) - (4y - 10) = 49 -2y
3y +24 = 49 -2y
5y +24 = 49
5y = 25
y = 5
To solve the equation 7(y + 2) – (4y – 10) = 44 – 2y + 5, distribute and combine like terms to simplify both sides of the equation. Isolate the variable y on one side of the equation by performing inverse operations. The solution to the equation is y = 3.
Explanation:To solve the equation 7(y + 2) – (4y – 10) = 44 – 2y + 5, we need to simplify both sides by distributing and combining like terms. Starting with the left side, we distribute 7 to both y and 2 to get 7y + 14. Then, distribute -1 to both 4y and -10 to get -4y + 10. Combining like terms, we have 7y + 14 - 4y + 10 = 44 - 2y + 5. Simplifying further gives us 3y + 24 = 39 - 2y. To isolate the variable y, we need to get all the y terms on one side. Adding 2y to both sides gives us 5y + 24 = 39. Finally, subtracting 24 from both sides yields 5y = 15. Dividing both sides by 5 gives us y = 3. Therefore, the solution to the equation is y = 3.

Final answer:
The quotient of -3/8 and negative 1/3 is 9/8. To get this result, multiply the first fraction by the reciprocal of the second fraction, and since both fractions are negative, the result is positive.
Explanation:
The question asks about the quotient when dividing two negative fractions, specifically -3/8 and negative 1/3. When dividing fractions, the rule is to multiply the first fraction by the reciprocal of the second fraction. Also, when dividing two negative numbers, the result is positive because a negative divided by a negative equals a positive.
To find the reciprocal of negative 1/3, we flip the numerator and denominator to get -3/1, which is -3. Then we keep the first fraction, change division to multiplication, and multiply by the reciprocal of the second fraction:
-3/8 × -3 (which is the reciprocal of negative 1/3)
When we multiply these, the negative signs cancel out and we get 3/8 × 3/1 = 9/8
Therefore, the quotient of -3/8 and negative 1/3 is 9/8, which is a positive number because the negatives cancel each other out as per the multiplication rules for signs.
Serena counts her calories over several days. What is her total caloric intake given these values: 1,405; 1,219; 1,119; 1,353.
For this case we add the quantities of calories consumed per day, that is:

If f(x)=5x^2 and g(x)=x-2 what is (fog)(-3)
Answer:
(fog)(-3) = 125
Step-by-step explanation:
So, we need to first evaluate g(-3) and then plug the value of g(-3) into f(x) to find (fog)(-3). So, let's do that:
[tex]g(-3) = -3-2 = -5[/tex]
[tex]f(g(-3)) = f(-5) = 5(-5)^2 = 5(25) = 125[/tex]

In a basketball match a team average 67 points over 10 games. After the next game the average is 68 points.
How many points did they score in the game?
Answer:
78 points
Step-by-step explanation:
Let x = sum of the 10 scores
x/10 = 67
x /10 *10 = 67* 10 = 670
The sum of the 10 scores is 670
Now we play 1 more game and score g
We want to find the average for the 11 games
The average is 68
(670 + g)/11 = 68
Multiply each side by 11
(670+g)/11 *11 = 68*11
670+g =748
Subtract 670 from each side
670+g-670 = 748-670
g =78

7x-2y=8
5x+2y=4
Answer:
x=1 y = -1/2
(1,-1/2)
Step-by-step explanation:
7x-2y=8
5x+2y=4
I would use elimination since we have 2y in one equation and -2y in the other
7x-2y=8
5x+2y=4
--------------------
12x = 12
Divide each side by 12
12x/12 = 12/12
x =1
The substitute back into equation 2
5(1) +2y = 4
5 +2y = 4
Subtract 5
5-5+2y = 4-5
2y = -1
Divide by 2
2y/2 = -1/2
y = -1/2
Answer:
The best method is the elimination method. The solution is (1, -1/2).
Step-by-step explanation:
7x - 2y = 8
5x + 2y = 4
12x = 12
x = 1
7(1) - 2y = 8
7 - 2y = 8
-2y = 1
y = -1/2

Answer:
x =[tex]\frac{1}{8}[/tex]
Step-by-step explanation:
[tex]\frac{3}{8}-x=[tex]\frac{1}{4}[/tex]
⇒ Minus [tex]\frac{3}{8}[/tex] from both sides
- x =[tex]-\frac{1}{8}[/tex]
⇒ Multiply both sides by -1 to get rid of negative
x =[tex]\frac{1}{8}[/tex]
Answer:
x = 1/8.
Step-by-step explanation:
3/8 - x = 1/4
Subtract 3/8 from both sides:
- x = 1/4 - 3/8
-x = 2/8 - 3/8
-x = -1/8
Divide both sides by -1:
x = 1/8.

What is the value of y?
Answer:
In my opinion the answer is y = 6
Step-by-step explanation:
We have two unknowns from the equation therefore, two equations are needed. These equations are:
3x + y = 9
y = –4x +10
To solve for y, we first substitute the second equation to the first one.
3x + –4x +10= 9
x = 1
We substitute the value of x to either of the equations and solve for y.
y = –4(1) +10
y = 6
Answer:
y=6
Step-by-step explanation:
[tex]3x + y = 9[/tex]
[tex]y = -4x + 10[/tex]
Substitute the value of y in the first equation:
[tex]3x + (-4x + 10) = 9[/tex]
Apply the subtraction property of equality:
[tex]-x + 10 = 9[/tex]
[tex]-x=-1[/tex]
x=1
Substitute 1 for x in the given y equation
[tex]y = -4x + 10[/tex]
[tex]y = -4(1)+ 10[/tex]
y=6
Solve the system of equations.

A hamburger bun merchant can ship 8 large boxes or 10 small boxes of hamburger buns into a carton for shipping. In one shipment, he sent a total of 96 boxes of hamburger buns. If there are more large boxes than small boxes, how many cartoons did he ship?
56 large boxes and 40 small boxes.
Step-by-step explanation:To solve this problem, we need to use the concept of multiples. By definition, a multiple of a number is that number multiplied by an integer. For instance, 3, 6, 9, 12 are multiples of 3. So let's do a chart and list the multiples of large and small boxes:
[tex]\begin{array}{cccccccccc}Number\,of\,boxes & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9\\Large & 8 & 16 & 24 & 32 & 40 & 48 & 56 & 64 & 72\\Small & 10 & 20 & 30 & 40 & 50 & 60 & 70 & 80 & 90\end{array}[/tex]
From this, our goal is to select the number of small and large boxes such that the sum is 96 boxes of hamburger burns and the number of large boxes is greater than the number of small boxes. From the table, the correct solution is:
56 large boxes and 40 small boxes, and this meets our requirement, because 56 + 40 = 96 and 56 > 40

Explanation:
If we had a pit stop every 1 mile, then we would have 36 pit stops. Note how 36/1 = 36.
If we had a pit stop every 2 miles, then we would have 18 pit stops because 36/2 = 18
If we had a pit stop every 3 miles, then we would have 12 pit stops because 36/3 = 12
And so on.
As you can see, we divide the total length 36 over the number of miles between pit stops. This applies even to fractions as well
Divide 36 over 4/6 to get
[tex]36 \div \frac{4}{6} = 36 \times \frac{6}{4} = 36 \times 1.5 = 54[/tex]
Recall that when you divide by a fraction, you flip the second fraction and multiply. The action of "flipping" is known as applying the reciprocal.
So this means there are 54 pit stops in total.
An alternative method to get the answer is to note that 4/6 = 0.66666667 approximately, and 36/0.66666667 = 53.99999973 which is very close to 54 that we got above. The reason why its not exactly 54 is because of rounding error. The more decimal digits you use, the more accurate the result will be.
What are the excluded values of x for x+4/-3x2+12x+36
Answer:
x = - 2, x = 6
Step-by-step explanation:
The denominator of the rational expression cannot be zero as this would make the expression undefined.
Equating the denominator to zero and solving gives the values that x cannot be.
Solve
- 3x² + 12x + 36 = 0 ( divide through by - 3 )
x² - 4x - 12 = 0 ← in standard form
(x - 6)(x + 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 2 = 0 ⇒ x = - 2
x = - 2 and x = 6 ← are the excluded values

Ying Zyiyu covered the first 300 miles of a trip going at 60 mph and the last hundred going at 40 mph. What was his average speed for the entire trip?
Answer:
53 1/3 mph
Step-by-step explanation:
Speed equals distance over time.
She covered 300 miles in 60mph, which took 5 hours.
(300/60=5 )
She also covered 100 miles in 40mph, which means she took 2.5 hours.
(100/40=2.5)
So the total distance is 400miles and the total time is 7.5 hours.
s=d/t substitute values which gives you 400/7.5 which equals 53 1/3 mph
