3x-4 = 6x-10
-4=6x-3x-10
-4=3x-10
-4+10=3x
3x=6
x=2
Answer:
B.
200x + 800 = 1,600; 4 months
Step-by-step explanation:
Since 200 is the amount you pay each month, and x is the months, we pay 200 dollars for each month. We also add 800 because that was the initial price she paid, which is known. We then complete the equation by making it equal to 1600 dollars, which is the total amount she paid.
When we get 200x + 800 = 1,600, we solve for x.
First, we minus 800 on each side to isolate x. 200x=1600-800
Then, we simplify, 200x=800
Lastly we divide by 200 on both sides to completely isolate x and complete the equation. 200x=800÷200
Simplify, getting x=4 (months)

Answer:
356.82
Step-by-step explanation:
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.
