Is there any answer choices? I believe it is 2/5
Answer:
9
Step-by-step explanation:
Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:
a-7=2
Add 7 to both sides:
a-7+7=2+7
a=9
Hope this helps!

Answer:
= 221
Step-by-step explanation:
Lenght = 250
Width= x
Perimeter = 2 (l+b) = 942
2 x (250 +x) = 942
500 + 2x = 942
2x = 942 - 500= 442
x = 442 /2 = 221
I hope Im right!!
