Answer:
59 yards x 99 yards
Step-by-step explanation:
Soccer fields are rectangular. If the width is W and the length is L:
316 = 2W + 2L
5841 = WL
We have two equations and two variables. Start by solving for one of the variables in the first equation:
316 = 2W + 2L
158 = W + L
W = 158 − L
Substitute into the second equation
5841 = (158 − L) L
5841 = 158 L − L²
L² − 158 L + 5841 = 0
Factor (or use quadratic formula):
(L − 59) (L − 99) = 0
L = 59 or 99
Find W:
W = 99 or 59
Therefore, the dimensions of the soccer field are 59 yards by 99 yards.
Answer:
To solve, we need to isolate the variable
The first step is to subtract 18 from both sides to "reverse" the addition
-6x+18=-6
-6x=-24
The second step is to divide -6 on both sides to "reverse" the multiplication
-6x=-24
x=4
Hope this helps! :)

Answer:
The price of the shirt is $7.50
The price of the pants is $18.50
Step-by-step explanation:
If you want to write something for your proof of work:
4x + 3x = 85.50
3 (4x + 3y ) = 3 (85.50)
12x + 9y = 256.50
12 × 7.50 = 90
9 × 18.50 = 166.50
ALSO for the last question:
12 × 7.50 = 90
20 × 18.50 = 370
370 + 90 = $460.00
Here the answer is 21 as the LCM of 14 and 6 is 42 and 42 is exactly divisible by 21.
