Answer:
339.42m
Step-by-step explanation:
Circumference of a circle=2x22/7x54
=339.42m
1. (2x + 1)(x - 7)
2. -x - 4
3. -31x -35
4. 57x + 112
5. (-x) (-x)
X= assistant's wage
x+15= instructor's wage
Add their wages set equal to $65
x + (x + 15)= 65
combine like terms
2x + 15= 65
subtract 15 from both sides
2x= 50
divide both sides by 2
x= $25 assistant's wage
x+15= 25 + 15= $40 instructor's wage
ANSWER: (C) $25 hourly wage of assistant
Hope this helps! :)
Let's represent h with the number of hours:
15h ≥ 200
h ≥ 200/15
h ≥ 40/3
h ≥ 13 1/3
He has to work at least 13 1/3 hours.
F(x)=7-3x g(x)=3x-7
First let’s solve for f(1)
f(1)= 7-3(1)
f(1)= 7-3
f(1)= 4 *we will save this for later
Let’s now solve for g(1)
g(1)= 3(1)-7
g(1)= 3-7
g(1)= -4
Now we can find f(1) + g(1)
f(1) =4 and g(1)= -4
4+(-4) = 0
