It would be (x) 8*3=24 since (y)10*3=30
so x=24
hope this helps!
Answer:
what
Step-by-step explanation:
Kate can travel 41.33 miles without exceeding her limit. This problem can be solved by using y = 2.25x + 7 linear equation with the "y" variable as the total cost that Kate must pay after she has traveled with the cab and the "x" variable as Kate's traveling distance. The equation has 7 for its constant value which is the $7 flat rate. We will find 41.33 miles as the traveling distance if we substituted the total cost with 100, which is the maximum amount that can be paid by Kate for the traveling purpose.
You will try all the cases and see if all the equations will match after substituting or no.
1.
5x
put x = 1/2
2.5 isn't equal to 20
4=15x
put x =1/2
15 × 1/3 =7.5
7.5 isn't equal to 4
-4x = 60
put x = 1/2
-4×1/2 = -2
-2 isn't equal to 60
30 = 60x
pit x = 1/2
60 × 1/2 = 30
30 = 30
Therefore, the correct answer is D. 30 = 60x
2. Answer is B. -4 , 4
Put x = -4
l 5 × -4 l = l-20l = 20
20 = 20
Put x = 4
l 5 × 4 l = l20l = 20
20 = 20
