Answer: George needs to work 12 hours to have enough money to buy the bicycle.
Step-by-step explanation
Needs $140
Saved $44
Makes $8hr
Step One: Make an equation
8h + 44 = 140
Step Two: Solve for h
8h + 44 = 140
-subtract 44 on both sides'
8h = 96
-divide 8 on both sides
h = 12
Step Three: Check your work
8h + 44 = 140
8(12) + 44 = 140
96 + 44 = 140
140 = 140
This week, the total = 3 + 4 + 3 = 10 miles
Last week = 8 miles.
The number more = 10 - 8 = 2 miles.
2 miles more.
1/3 from 6 (the amount of girls with glasses) / 18 (total number of students)
Answer:
Step-by-step explanation: add the equations
2x² = 30
x² = 15
y² = 12 - 15
= -3
x4 -y4 = 15² - (-3)²
= 216
