I’m pretty sure it’s the 4th option (division) because when you solve with division it gets you -32.
The formula for circumference is 2π r
So solve like this:
c= 2π r
62.8 = 3.14 · r
20 = r (divide 62.8 by 3.14)
Assign variables to you unknowns.
c = $ cars
t = $ trucks
6c + 3t = 4800
8c + t = 4600
use substitution or elimination to solve the system of equations.
using elimination.. multiply second equation by -3 and add to the other to combine equations into one.
6c + 3t = 4800
-3(8c + t = 4600)
---------------------------
-18c + 0 = -9000
c = 9000/18
c = 500 $
use this in one of the equations to find the cost of a truck.
8(500) + t = 4600
4000 + t = 4600
t = 4600 - 4000
t = 600 $
question asks
2(500) + 3(600) =
1000 + 1800 = 2800 $
Answer:
I believe the answer is $2,000.
Step-by-step explanation:
$8,000 in 4 yrs
The same in each year
year one=2,000
year two=2,000
year three=2,000
year four=2,000
Since there is 4 years and the total is 8,000 to pay over the four years, then it is 8,000/4 = 2,000
