Answer:
Step-by-step explanation:
Solve each equation and compare the solutions
1.
- 2(a - 1.1) = 5.8
- a - 1.1 = 5.8/2
- a - 1.1 = 2.9
- a = 2.9 + 1.1
- a = 4
2.
- (5/2)b - 2 3/4 = 7 1/4
- 2.5b = 7 1/4 + 2 3/4
- 2.5b = 10
- b = 10/2.5
- b = 4
Both a and b have same value
Answer:
12.6 square feet
Step-by-step explanation:
So first we set it up:
18ft is 100% of the original
and the area of the copies are 70%
Copies: x
x/70 = 18/100
70(18) = 1260
1260/100 = 12.6
x = 12.6
3n+2n+4=9n+12
5n+4=9n+12
4-12=9n-5n
-8=4n
Divide both sides by 4
n=-2
Some ordered pairs are:(10,5), (0,9), and (3,15) that make the equation true.
