-12 = 4x + 8, with x representing the number
Minus eight from both sides
-20 = 4x
Divide both sides by four
x = -5
Answer:
(If solving for x) X = 2y-1
Step-by-step explanation:
Y-2 = 1/2(x-3)
Distributive property
Y-2 = 1/2x - 1.5
Addition property of equality
Y-0.5=1/2x
Multiplication property
2Y-1=X
Symmetric property
X = 2y-1
Y=x^2 + 16 is the correct answer to your question
First, set it up as variables
W=x
L=2x+3
apply perimeter formula and solve
2(x+2x+3)=66
2(3x+3)=66
6x+6=66
6x=60
x=10
width=10
length=23
area= 230
1.7 miles: subtract 1.5 from 3.2 which equals 1.7 (make sure to line up the decimals!)
