Part A) First, you need to find out how much she makes each hour.40/5 = 8 & 48/6 = 8 ... This shows that she makes $8 an hour
To find the first missing number, you will do 8 * 8 = 64 ... This shows that she makes $64 in 8 hours.
To find the second missing number, you will do 56/8 = 7 ... This shows that she makes $56 in 7 hours.
Part B) Barb makes $9 every hour. To find the amount of money she earns for 5, 6, and 8 hours of work you will need to multiply $9 by the amount of hours she worked.
9 * 5 = 45 ... This shows that she makes $45 in 5 hours.
9 * 6 = 54 ... This shows that she makes $54 in 6 hours.
9 * 8 = 72 ... This shows that she makes $72 in 8 hours.
Part C) In part B, you found out how much she makes after working at the theme park for 5 hours. ($45 in 5 hours)
Next, you'll need to find out how much she makes after mowing lawns for 5 hours.
5*8 = $40 ... This shows that she makes $40 in 8 hours
Now you need to the difference. 45 - 40 = 5 ... She makes 5 more dollars working at the theme park for 5 hours than mowing lawns for 5 hours.
Answer:
b = -9.
Step-by-step explanation:
The line passes through (4, 3) and (7, 12). First, we need to find the slope: the rise over the run.
(12 - 3) / (7 - 4) = 9 / 3 = 3.
Now that we have the slope, we can say that m = 3. So, we have an equation of y = 3x + b. To find b, we can use M(4, 3) and say that y = 3 and x = 4.
3 = 3 * 4 + b
b + 12 = 3
b = -9.
Hope this helps!
