Answer:
C(t) = 9t + 14
Step-by-step explanation:
write two equations with the given information
x + 6y = 68
x + 3y = 41
(x and y are just random variables, with x being the number of credits from high school and y being the number of credits earned each semester)
subtract (x+3y=41) from (x+6y=68) to get 3y=27
y = 9
then plug back in to one of the equations to find x
x + 3(9) = 41
x + 27 = 41
x = 14
then write the equation for C(t)
C(t) = 9t + 14
because you start with 14 credits from high school then add 9 credits for each semester taken
Answer:
2250 ft ²
Step-by-step explanation:
Lawn is 50 feet across on each side so
Base (b) = 50ft
From front to back it is measured 45 feet so
height (h) = 45ft
Area of lawn = b x h
= 50 x 45
= 2250 ft²
If we take 12 to be the 100%, now 15 - 12, so is 3 bucks up for the retail price, what is 3 off 12 in percentage then?
Answer:
456 
Step-by-step explanation:
Find the height of the trapezoid first (QR):
= 12
QR = 12
Area:
× h = 
× 12
= 456
