3x is less than or greater to 27 is what I got
11 HOMES TO 8 AWAYS IS THE ANSWER
X = y + 7
49 = x + y
49 = y + y + 7
49 = 2y + 7
42 = 2y
y = 21
x = 21 + 7
You have 21 dimes and 28 quarters
Answer:
The answer is C: the distance is 5 times the swing speed
Step-by-step explanation:

Answer:
x = 10
Step-by-step explanation:
the area of a square = s² ( s is the side length )
s² = (4x + 3)² ( take the square root of both sides )
s = = 4x + 3
perimeter = 4s = 172, that is
4(4x + 3) = 172 ( distribute left side )
16x + 12 = 172 ( subtract 12 from both sides )
16x = 160 ( divide both sides by 16 )
x = 10
