Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
1/5
Step-by-step explanation:
divide each side by 5
5x/5=1/5
simplify
x/5=1/5
H = hour
A = 60 + (25h) = ?
B = 120 + (20h) = ?
60 hours because 28 hours for company A x 25 dollars = 700 + starting fee is 60
28 x 25 = 700 + 60 = 760
32 hours for company B x 20 dollars = 640 + starting fee is 120
32 x 20 = 640 + 120 = 760
32 hours + 28 hours = 60 hours all together. It takes 60 hours cost the same
A= 25 x 7 + 60 = 235
25 x 7 = 175 + 60 = 235
B = 20 x 7 + 120 = 260
20 x 7 = 140 + 120 = 260
235 < 260
The cheaper one is A with 235
Answer:
C.
Step-by-step explanation:
Using the formula for slope, we can find out that
So -105 is the slope, and because she bought her laptop at $1160, the y-intercept is 1160. This means that the equation is V(t)=-105t+1160.
