Answer:

A. The value of x is 5

B. The length of each side is 20!

Step-by-step explanation:

For part A., We can determine x by setting these equations to equal each other (as we know that all sides of a square are equal)! See below for how to:

$4x = 2x +10\\2x = 10\\x=5$

For part B. sub x for 5 to get the side length of one side...

$4(5) = 20\\2(5) +10=20$

We already know that all sides are equal, so the side length of each side is 20!

Jade buys a blouse and a skirt for 34 of their original price. She pays a total of $31.50 for the two items. If the original pri

Shtirlitz [24]

Answer:

`Part A:

D. 3/4(18 + s) = 31.50

Part B:

$36

Step-by-step explanation:

I think 34 is 3/4, is that right?

here, s is the cost of the skirt

Part A: The answer would be:

3/4(18) + 3/4(s) = 31.5 =

3/4(18 + s) = 31.5

Part B: 3/4(18) + 3/4(s) = 31.5

4.5 + 3/4s = 31.5

Subtract 4.5 from both sides:

3/4s = 27, 27 is the cost of the skirt now, but we need the original price.

multiply both sides by 4/3:

s = 36

PLEASEPLEASEPLEASE HELP!!!!!!!!!!! Don't mind to much of the notes, I think y=23, but what is x??

REVISED

Answer:

x = 15.33

Step-by-step explanation:

3y is equal to 2x + 13. The reason why is because they are corresponding angles, (right next to each other). From there, you would have to substitute y into 3y. The equation should look like: 3(23) = 2x + 13. All that is left is to solve for x.

If a rectangle has a base of 6 units, and a height of 8 units, what is its area?

Morgarella [4.7K]

Answer:

a=48 units^2

Step-by-step explanation:

The area of a rectangle can be found using:

a=bh

We know the base is 6, and the height is 8, so we can substitute them in

a=6*8

a=48

Area uses units squared, so,

a=48 units^2
