Answer: $56.25
Step-by-step explanation: We know that Bonita makes $11.75 per hour and Bruce makes $12.50 per hour.
To find out how much money Bonita makes if she worked 25 hours, we can multiply the amount she makes per each hour.
$11.75 x 25 hours = $293.75 for 25 hours of work.
We can do the same thing for Bruce.
$12.50 x 19 hours = $237.50 for 19 hours of work.
Now to find the difference in the amount of money they each earned. You can simply subtract $237.50 from $293.75.
$293.75 - $237.50 = $56.25
Create formulas for length and perimeter.
L = 4/W
10 = 2*L + 2*W
Substitute formula for length for the length in perimeter formula
10 = 2*4/W + 2*W
10 = 8/W + 2*W
5 = 4/W + W
5W = 4 + W^2
0 = 4 - 5W + W^2
W^2 -5W + 4 = 0
You now have a standard quadratic equation with A=1, B=-5, and C=4
Using the quadratic formula you get two possible answers
W = 1, or W = 4
Let's check them
Width = 1, L = 4/1 = 4
Width = 4, L = 4/4 = 1
Both make the same 1x4 rectangle. And the perimeter is 2*1 + 2*4 = 2+8 = 10
- - Solve:
Start of by simplifying both sides of your problem.
3*2x+3*-7=32
6w+-21=3
6w-21=3
- - Now you need to add 21 to both sides to be able to finish solving.
6w-21+21=3+21
6w=34
- - Final step:
Answer: w=4
Answer:
First picture: -4,913
Second picture: 20.25
Step-by-step explanation:
-17^5/-17^2 = -17^3
-17 × -17 × -17 = -4913
4.5^5/4.5^3 = 4.5^2
4.5 × 4.5 = 20.25
Do you see how I had the same whole number on the top and bottom? (17 was on top and 17 was on bottom)
The exponents were those tiny numbers you saw.
Whenever you are dividing by the same whole number (-17/-17), you can subtract exponents.
When you multiply the same whole number, you can add the exponents.
Hope this helps! Best of luck :)
