Answer:
The bike costs $130.
Step-by-step explanation:
1) 200 x 0.35 = 70
2) 200 - 70 = 130
Solve for x:
1.
4x - 7 = 3
Add 7 to both sides
4x = 10
Divide both sides by 4
x = 10/4
Simplify:
x = 5/2
Answer for question 1: x = 5/2
2.
13 + 2x/3 = 15
Multiply both sides by 3
39 + 2x = 45
Subtract 39 from both sides
2x = 6
Divide both sides by 2
x = 3
Answer for question 2: x = 3
3.
10x + 7 = 15
Subtract 7 from both sides
10x = 8
Divide both sides by 10
x = 8/10
Simplify
x = 4/5
Answer for question 3: x = 4/5
Answer:
Step-by-step explanation:
a=lw
a=100x^2+60x+9
(10x)^2+60x+3^2
(10x+3)^2=a
a=(10x+3)(10x+3)
