Answer:
5 = 6q - 30 - 19
5 = 6q - 49
54 = 6q
9 = q
Step-by-step explanation:
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
Answer:
The perimeter of the triangle can be expressed as 5x + 18.
Step-by-step explanation:
Perimeter of an object is the sum of the length of its sides.
For the required triangle, we have;
length of the base = x
length of the second side = 3x + 9
length of the third side = x + 9
Perimeter of the triangle = length of the base + length of the second side + length of the third side
= x + (3x + 9) + (x + 9)
= x + 3x + 9 + x + 9
= 5x + 18
The perimeter of the triangle can be expressed as 5x + 18.
