Answer:
X=3
Step-by-step explanation:
Since all the sides of a square are equal, hence;
5x-2 = x+10
Collect like terms
5x-x = 10+2
4x =12
X = 12/4
X =3
Hence the value of x is 3

What is one-fifth of a number, x, increased by 24 is equal to eight tenths of the same number, x.
Answer:
x = 40
Step-by-step explanation:
(x × [tex]\frac{1}{5}[/tex] )+ 24 = [tex]\frac{8}{10}[/tex] × x
0.2x + 24 = 0.8x
0.2x - 0.2x + 24 = 0.8x - 0.2x
24 = 0.6x
0.6x = 24
0.6x × [tex]1\frac{2}{3}[/tex] = 24 × [tex]1\frac{2}{3}[/tex]
x = 40
Answer:
x=40
Step-by-step explanation:
1/5x+24=8/10x
give like denominators
2/10x+24=8/10x
subtract 2/10x on both sides
24=6/10x
divide 24 by 6/10, or multiply by 10/6
x=240/6
refine/simplify
x=40

Part A: Determine the unit rate for the amount of one T-shirt. Explain how you determined the unit rate.
9514 1404 393
Answer:
$15
Step-by-step explanation:
The desired rate is ...
"unit rate" = cost/T-shirt = $180/(12 T-shirts) = $15/T-shirt
__
The unit rate is based on its definition. Here, the rate of interest is the cost per shirt, so it is found by dividing the cost by the number of shirts.

A system of weights that is generally used in the United States, with the exception of precious metals, stones, and pharmaceuticals, and is based on a pound weighing 16 ounces and an ounce weighing 437.5 grains (28.350 grams).
