Answer:
the answer is A
Step-by-step explanation:
410 is the total amount paid
so 50 dollars was a base fee for the service charge
and 90 was per tire. Because we dont know how many tires she bought 90 x number of tires(t) = 90t
so 410 dollars = 50 dollars(service fee) + 90 dollars ( multilied by number of tires "t")

Answer:
x = - 2
y = 6
Step-by-step explanation:
The best way to do this is to put - 3x in for y in the second equation.
4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.
4x - - 6x = -20 Change - - 6x to 6x
4x + 6x = - 20 Add
10x = - 20 Divide by 10
x = -20/10
x = - 2
============================
Find y
y = - 3x
y = -3 * -2
y = 6
24! 2 plus 4 is 6 and 6 times 4 for the scale factor
