Combine like terms.
4t+7=-33
subtract 7 from both sides
4t=-40
divide both sides by 4
t=-10
26.
Subtract 2a from both sides
5=7a-16
add 16 to both sides
21=7a
divideby 7 on both sides
a = 3

Answer:
the number of miles is 160
Step-by-step explanation:
The computation is given below:
Let us assume the miles be x
For company A
y = $100 + $0.40x
And, for company B
y = $20 + $0.90x
In order to find out the number of miles, the rental cost of the company A should be less than the company B rental cost
SO,
$20 + $0.90x > $100 + $0.40x
Subtract $20 from both sides
0.90x > 80 + 0.40x
Now subtract 0.40x from both sides
0.50x >80
x>160
So the number of miles is 160
