Answer:
give me brainliest plz
Step-by-step explanation:
(a+d)/a = (a+4d)/(a+d)
d = 2a
so, (a+d)/a = 3
Answer:
a = 6 and b = 36
Step-by-step explanation:
Set up equations:
b = 30 + a
b = 6a
Subtract the two equations:
b = 6a
- (b = 30 + a)
5a - 30 = 0
5a = 30
divide both sides by 5
a = 6
Plug a = 6 into the original equation:
b = 30 + 6
b = 36
you could also do:
b = 6 * 6
b = 36
Answer: w = 18
Step-by-step explanation:
2w + 2(w+6) = 84
Distribute: 2w + 2w + 12 = 84
4w + 12 = 84
4w=72
