-9 + 5y - 7y + 3y = ?

Answers

Answer 1

Answer:

-9 + y

Step-by-step explanation:

For this problem, you have to combine like terms.

-9 is the only number that doesn't have a variable.

5y, -7y, 3y have all the the same variables, so we'll combine those.

5y - 7y = -2y

-2y + 3y = 1y

Solution: -9 + y

Anais bought 4 1/2 yards of ribbon. She had 3 feet 8 inches of ribbon left after trimming some curtains. How many inches of ribbon did anais use to trim the curtains

Answers

Answer:

First convert all numbers into inches since that is the answer being solved for.

1 yard =36 inches

4.5 x 36 = 1,620 inches

1 foot = 12 inches

3 x 12 = 36 inches

36 + 8 = 44 inches

Now take 1,620 inches (starting ribbon measure) and subtract 44 inches (what was left over) to get the inches used to trim curtains.

1,620 inches - 44inches =

1,576 inches were used to trim the curtains.

Wezi has sixty-three $5-bills. He takes the $5-bills to the bank to exchange them for $20-bills. How many $20-bills does Wezi get? Is there money left over? Explain.

Answers

Answer: 15

Step-by-step explanation:

From the question, we are informed that Wezi has sixty-three $5-bills. The total amount that he has will be:

= 63 × $5

= $315

We are further told that he takes the $5-bills to the bank to exchange them for $20-bills. Based on this, the number of $20-bills that Wezi get will be:

= $315 / $20

= 15 3/4

Therefore, he will get 15 $20 bills

Answer:

56 square feet

Step-by-step explanation:

If you take the problem and divide into two rectangles by drawing the line up from the bottom 4.

You end up with one rectangle that is

8x4

and a second thats

4x6.

The area is then calculated by taking the length and multiplying by the width of the first (8 x 4) and adding to the same process of the second (4x6)

Thus

32 + 24 = 56 square feet

Answer:

32 + 24 = 56 square feet

Answers

Answer:

7x - 7

Step-by-step explanation:

In this equation you are going to add like terms.

The like terms you have are the terms with x and then the terms without the x.

So 4x + 3x = 7x

5 - 12 = -7

So your answer is 7x-7

Answers

Answer:

The subject 'x' in terms of 'y'

[tex]x = \sqrt{\frac{y+2}{3} }[/tex]

Step-by-step explanation:

Explanation:-

Given subject in terms of 'x'

 y = 3 x² - 2

Adding '2' on both sides, we get

y + 2 = 3 x² - 2 +2

y+2 =  3 x²

Dividing '3' on both sides, we get

[tex]x^{2} = \frac{y+2}{3}[/tex]

[tex]x = \sqrt{\frac{y+2}{3} }[/tex]

The diagram below models the diameter of the bicycle wheel
21.75
Which of the following is closest to the distance of the length when the bicycle wheel
makes 1 revolution?
A7 inches
B 25 inches
C34 inches
D69 inches


Can anyone help me!!

Answers

Answer: (21.75 / 2) * 2 * pi = 68.42...in, answer D.

Explanation: one revolution from a wheel will be a 360 degree rotation, meaning that if you had laid your finger on the outside of the wheel as it made its full rotation, your finger would have touched the entire circumference of the wheel. Thus, we can represent the length of 1 revolution as the circumference. Thus we take the diameter, and divide it by 2 to get the radius. Then we simply multiply by 2 * pi * r (r = radius). This is the formula for the circumference of a circle.
