Answer:
Present age of the car = 1.5 years and the tires are 0.5 years old.
Step-by-step explanation:
Let the present age of the car be x years and that of the tires be y years.
x = 3y
x = y + 1
3y = y + 1
2y = 1
y = 0.5.
x = 3*0.5 = 1.5.
C and D
the volume ( V) of a pyramid is found using the formula
V = 
× area of base × height
calculating each of the volumes gives
(A) V = × 10.5 × 6 = 21 in³
(B) V = × 3.6 × 8 = 9.6 in³
(C) V = × 4.2 × 12 = 16,8 in³
(D) V = × 6 × 8.4 = 16.8 in³
C and D have equal volumes
Hello,
So Y variable is what you would start with.
20 <= he'll start off with for a
40 <= what he'll start off with for b
And X variables would be the # of hours you're working.
10 <= meaning every hour worked is worth 10 dollars
5 <= meaning every hour worked will be paid 5 dollars
So let's just say for option a he works two hours
(Option A)
10 (2) + 20
20 + 20
= 40
(Option B)
5 (2) + 40
10 + 40
50
As for your equations
Y = 10x + 40
Y= 5x + 40
