Answer:
D.144
Step-by-step explanation:
⇔ 84x = -7x + 1092
⇔ 91x = 1092
⇔ x = 12
⇒ AC = 156 - x = 156 - 12 = 144

Answer:
3 < x < 11
Step-by-step explanation:
We use the triangle inequality to figure out the longest possible side and shortest possible side. The shortest will be 3 (8-5 = 3) and the longest will be 11 (3+8 = 11) and we write an inequality.
Answer:
Assuming there are no other parts,
the Whole = A + B is the denominator:
Whole = 3 + 9 = 12
Part A = 3 and Part B = 9 are numerators for each fraction.
The fractions are then:
3/12 and 9/12
Meaning:
Part A is 3/12 of the whole
Part B is 9/12 of the whole
Reducing the fractions, it is also true that:
Part A = 1/4 of the whole
Part B = 3/4 of the whole
