True It forms a 30, 60, 90 triangle and 3, 4, and 5 are what we call a Pythagorean Triple, If you don't know what that is, ask your teacher, I'm sure they will either get to it later or will tell you right then and there! :)
For 7=s-9 you add 9 to both sides and the answer will be s=16.
Answer:
y = 2
Step-by-step explanation:
y = |x| - 5
|?| means an absolute value of a number
in this case x = -7 so the absolute value for -7 would be 7
y = 7 - 5
y = 2
15.40 + 8.50l (l is variable for labor)
8.50 x 2.5 = 21.25
15.40 + 21.25 = 36.65.
That is the answer for A.
504.20 - 15.40 = 488.80
488.80 / 8.50 = <span>57.50
About 57.50 hours for B.</span>
