-10.
Solution: Multiply the negative three fourths by everything in the parenthesis.

Add the negative three halves to both sides.

Multiply both sides by negative four thirds.

If a is directly proportional to b, we have the relationship to be:

When a = 25, b = 35. Therefore, we can calculate the value of k as follows:

Therefore, the relationship is given to be:

When a = 40, we can calculate the value of b to be:

The value of b is 56.
Answer:
$1.5
Step-by-step explanation:
So you need to subtract 25 from 13 = 12 then take 3 and 5 and add = 8 then you need to divide 12 from 8 = 1.5 so i do believe that the tubes are $1.5
I may be wrong and im sorry but pls try :3
When dividing these, the powers are subtracted form each other.
We could split up the fraction into r's, s's, and t's.
r^-3 / r^2 = r^-5 [think of it as -3 -2]
s^5 / s = s^4
t^2 / t^-2 = t^4 [2 - - 2 = 4]
A negative power places it on the bottom of the fraction and the minus sign is removed from the power.
So the answer is A: (s^4)(t^4)/r^5
