Answer:
1). 24
2). 8
Explanation:
1).
285$ - 45$ = 240$
240$/10 = 24$
Therefore, he pays 24$ a month.
2).
Let x be the number than triple:
3x - 5 = 19
3x = 19 + 5
3x = 24
x = 24/3
x = 8
For this case, we must find the triangle whose value of x is given by 17.
In all three cases, the value of the variable "x" is given by:
Triangle 1:
Triangle 2:
Triangle 3:
Thus, the triangle whose value of x is 17 is triangle 2.
