You have saved $125 to put toward a new bike that cost $500. if you save $20 per week, how long will it take you to save enough to cover the cost? (inequalities)

In 19 weeks I will have enough money to buy the bike.

Step-by-step explanation:

Saved Money = $125.

Needed Money = $500-$125= $375

In 1 week $20  so  $375/$20 = 18.75 weeks

In 19 weeks it would be $19*20= $380  

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
