7 is bases number two , I'm not sure it sounds like similar makes more sense , but not sure for 2
Answer:
PQ = 18
Step-by-step explanation:
If R is the midpoint of PQ, then PR = RQ
⇒ 6x + 7 = 3x + 8
⇒ 3x = 1
⇒ x = 1/3
So PR = 6x + 7 = 6(1/3) + 7 = 9
and RQ = 3x + 8 = 3(1/3) + 8 = 9
⇒ PQ = PR + RQ = 9 + 9 = 18
Answer:
x≥ -4/55, x≤−89
Step-by-step explanation:
Step 1: Subtract 1 from both sides.
−110x+1−1≤9−1
−110x≤8
Step 2: Divide both sides by -110.
−110x/-110≤8/-110
x≥ -4/55
