<span>-5m+17=52
Subtract 17 from both sides
-5m= 35
Divide -5 on both sides
Final Answer: m= -7</span>
Answer:
Here we will explain how to calculate one half of 80.
One half of 80 is simply one half times 80, which can be written as follows:
One/half x 80
Furthermore, you can convert "one" to "1" and "half" to "2" and then the equation and answer is:
1/2 x 80 = 40.00

Answer:
15 black water bottles
Step-by-step explanation:
let w represent white water bottles, and let b represent black water bottles.
set up a system of equations:
w+b=20
w+2b=35
(the top equation shows that the number of white water bottles he sold and the number of black water bottles he sold equals to 20, since it says that the total number of water bottles is 20. the bottom equation shows that white water bottles cost $1, and black water bottles cost $2, and that the total amount of money he got from selling them is $35).
in the top equation, isolate w:
w+b=20
w=20-b
now we do substitution. in the bottom equation, substitute 20-b for w:
w+2b=35
20-b+2b=35
then, solve:
b+20=35
b=15
this means that he sold 15 black water bottles.
The area of the outer square = (x+5)² = x² + 10x + 25
The area of the inner square = (x-2)² = x² - 4x + 4
The area of the shaded region = (x² + 10x + 25) - (x² - 4x + 4)
= x² + 10x + 25 - x² + 4x - 4
= 14x + 21 square units
