Answer:
x = 9
Step-by-step explanation:
AB = 4x + 6 and BC = 7x + 15 AC is the sum of AB and BC
so 4x + 6 + 7x + 15 = 120 add like terms
11x + 21 = 120 subtract 21 from both sides
11x = 99 divide both sides by 11
Answer: Should be 7.6745982363164 times larger
6x
3x/y=x/2y
Since 2y is 2X greater than y, 6x is 2X greater than 3x.
So,
The answer is 6x.
z ≤ 7
9x - 7 ≤ 28 + 4x
9x - 4x ≤ 28 + 7
5x ≤ 35
x ≤ 35 / 5
x ≤ 7
