Answer:

z=4

Step-by-step explanation:

You would distribute the negative sign outside of the parentheses and get:

2z-z+1=5z-15

Then combine like terms and get:

z+1=5z-15

Subtract 5z from both sides:

-4z+1=-15

Subtract 1 from both sides:

-4z=-16

Then divide both sides by -4:

z=4

Yuki bought a pound of confetti for \$12$12. What is the price, in dollars, per ounce of confetti? There are 1616 ounces in 11 p

tatiyna

Answer:

$0.75

Step-by-step explanation:

We have been given that Yuki bought a pound of confetti for $12.

To find the price of per ounce of confetti, we will divide the total price of 1 pound confetti by number of ounces in 1 pound.

1 pound = 16 ounces.

Let us divide 12 by 16 to find the price of confetti per ounce.

$\text{Price of per ounce confetti}=\frac{12}{16}$

$\text{Price of per ounce confetti}=\frac{3}{4}$

$\text{Price of per ounce confetti}=0.75$

Therefore, the price of per ounce confetti is $0.75.

What is the area of a rectangle with vertices at (2,3), (7,3), (7,10), and (2, 10)?

8090 [49]

Answer:

45 units.

Step-by-step explanation:

First, let's find the length!

We need to ignore x and focus on y. Subtract 3 from 10, your answer should be 7. Therefore, the length is 7 units.

Now, let's find the width!

We need to ignore y and now focus on x. Subtract 2 from 7, your answer should be 5. Therefore, the length is 5 units.

The formula of the area of a rectangle is: l * w

Therefore: 7 * 5 = 45 units

REMEMBER: When dealing with rectangles on a graph, x is the width while y is the length!

Next time, I suggest you use some graph paper and jot down all the vertices! Hope this helps. Please mark as brainliest and have a great day!
