Answer:
Option B, 8/5 hr
Step-by-step explanation:
1/2 + 1/8
1*4 / 2*4 + 1/8
4/8 + 1/8
5/8 = 1/t
5t / 5 = 8 / 5
t = 8/5
Answer: Option B, 8/5 hr
Answer:
A
Step-by-step explanation:
6r - 17r = -66
Subtract like terms.
-11r = -66
Divide both sides by -11.
r = -66/-11
r = 6
Answer:
x=11/3
Step-by-step explanation:
x-4+3x=8-2x+10
4x-4=18-2x
6x=22
x=22/6
Answer:
C
Step-by-step explanation:
Convert the equation into slope intercept form : y=mx+b
2y=x+4
y=1/2x + 2
The m is the slope and the b is the y intercept
In this equation, the slope is 1/2 and the y intercept is 2
The only graph with y intercept 2 is C
4300×.30 = 1290
Her costs should be no more than $1290
