Step-by-step explanation:
A - 2.5 = 1.5
A = 1.5 + 2.5 (Add 2.5 on both sides)
A = 4.
Answer:
numerator divided by denominator
Step-by-step explanation:
Answer:
a) 
b) 
Step-by-step explanation:
In both parts of the problem y varies directly as x. So, they have the following form:

Where k is the constant of proportionality.
Therefore, you must find k and then write the equations.
a) Solve for k:

Then, the equation is:

b) Solve for k:

Then, the equation is:

Answer:
x = 3
Step-by-step explanation:
5(2 - x) = 7x - 26
Distribute;
10 - 5x = 7x - 26
Add 5x to both sides;
10 = 12x - 26
Add 26 to both sides;
36 = 12x
Divide both sides by 12;
x = 3
