Father = x
son = y
x-5 = 7(y-5)
x +5 = 3(y+5) solve the system
x-5 = 7y-35
x+5 = 3y +15
x-5 = 7y-35
-x-5 = -3y -15
-10 = 4y -50
+50 +50
40 = 4y
10 = y
Solve for X
x+5 = 3(10) + 15
x+5 = 45
x = 40
The father is 40yrs old and the son is 10yrs old.

<u>Answer:</u>
C. Each additional t-shirt being printed will increase the total cost by $11.
<u>Step-by-step explanation:</u>
We know that the total cost of custom t-shirts, y, in dollars, for x t-shirts is given by:

Here 11 is the price of the shirt, x is the number of shirts that are printed and 25 might be some additional charges.
For each additional shirt that is printed, the total price, y, will increase by $11 so the correct answer option is C.

Answer:
V = 4.187r³
Step-by-step explanation:
Volume of a sphere is expressed using the formula;
V = 4/3πr³
r is the radius
Substitute π = 3.14 into the formula
V = 4/3 * 3.14r³
V = 4.187r³
Hence the volume of a sphere in terms of the radius is V = 4.187r³
