Answer:
1. x=5
2.x=-33/8
3.x=10
4.x=5
Step-by-step explanation:
Answer:
93
Step-by-step explanation:
15 x 5 = 75 + 18 = 93
So, we have the information:
Save $10 first month
$5 the next months
X = amount of months
Cost = 175
So, it will take 7 months.
10+15+20+25+30+35+40 = 175
Answer:
x=-8
Step-by-step explanation:
1 Simplify 1/10x to x/10.
x/10 + 9/10 = 1/10
2 Join the denominators.
x+9/10 = 1/10
3 Multiply both sides by 10.
x+9 = 1/10×10
4 Cancel 10.
x+9=1
5 Subtract 9 from both sides.
x=1-9
6 Simplify 1-9 to -8.
x=-8
