Pick your favorite number and square it.
Squaring a number means you multiply it by itself.
Let's say you picked the number 7
7 squared = 7^2 = 7*7 = 49
Think of a 7 by 7 grid of tiny squares. There would be 49 total little squares to represent the total area. Graph paper might help visualize this.
The answer is b to this qestion
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:
x = 1
Step-by-step explanation:
Add 4 from both sides which you add to the zero. Then, combine like terms, 5x - 1x which is 4x. Divide 4 from both sides and it equals 1.
