Where’s the figure? Or numbers?
The answer is 7x + 3
First, you have 3x-1 + 2x+1
Combine like terms and the 1’s cancel each other out. You are left with 5x.
Then, you add x+2 + x+1
Combine like terms and you have 2x+3
Add 5x + 2x+3 and you have 7x +3
I’m bad at explaining, so here are the steps.
A linear equation that relates the cost of c in dollars of renting a truck to the number x of miles driven is c = 0.09x + 39, and the cost of renting the truck if the truck is driven 187 miles and 319 miles is equal to $55.83 and $67.71 respectively.
If the rental company rents a truck by charging $34 and 0.09$ per mile, the liner equation can be given as
c = 0.09x + 39
where c represents the cost in dollars of renting the truck and x represents the number of miles
If the truck is driven 187 miles, it can be calculated using the linear equations as follows,
c = 0.09x + 39
As x = 187
c = 0.09 (187) + 39
c = 16.83 + 39
c = 55.83
If the truck is driven 319 miles, it can be calculated using the linear equations as follows,
c = 0.09x + 39
As x = 319
c = 0.09 (319) + 39
c = 28.71 + 39
c = 67.71
Hence the cost in dollars of renting the truck if the truck is driven 187 miles and 319 miles is calculated to be 55.83 and 67.71 respectively.
