Answer:
The total bill is $6900 because 69 is a man which hair is multi colour
Problem 1 Answer: x = 17 + -4y
Show Work:
1) Simplifying
x + 4y = 17
2) Solving
x + 4y = 17
3) Solving for variable 'x'.
4) Move all terms containing x to the left, all other terms to the right.
5) Add '-4y' to each side of the equation.
x + 4y + -4y = 17 + -4y
6) Combine like terms: 4y + -4y = 0
x + 0 = 17 + -4y
x = 17 + -4y
7) Simplifying
x = 17 + -4y
Problem 2 Answer: x = 7/8y + 29/4
Step 1: Add 7y to both sides.
8x−7y+7y=58+7y
8x=7y+58
Step 2: Divide both sides by 8.
8x/8 = 7y+58/8
x = 7/8y + 24/9
Answer:it take the hawk 100 seconds to dive -70 meters
Step-by-step explanation:
A red-tailed hawk dives at a constant rate in which its altitude changes by -7meters in 10 second. Therefore, the rate at which his altitude changes per second would be
- 7/10 = - 0.7 meters per second
Time = distance / speed
Therefore, the time it will take the hawk to dive -70 meters would be
- 70/- 0.7 = 100 seconds
It will be 52 as you know when looking at a triangle with 3 angles they must all add up to 180 so you simply do 56+72 then subtract 180 from it and you get 52.
