Lin's number = l
pazi's number = p
l = p + 7
p = p
p + 7 + p = 49
2p + 7 = 49
2p + 7 (-7) = 49 (-7)
2p = 42
2p/2 = 42/2
p = 21
l = p + 7
l = 21 + 7
l = 28
pazi is 21 years old, Lin is 28 years old
hope this helps

Answer:
Let a be the first term.
The sum is a1−r=33.25.
The second term is ar=7.98, so a=7.98/r.
Putting these together, 7.98/r(1−r)=33.25 or r(1−r)=0.24=0.6×0.4.
If the answer doesn't jump out at you from there, you could solve for r with the quadratic formula.

Answer:
First should get $220, other two should get $140 each.
Step-by-step explanation:
The ratio of hours the friends worked is 11:7:7. Say that they are paid 11x, 7x, and 7x respectively, therefore:
11x + 7x + 7x = 500
25x = 500
x = 20 so the first friend should get 11 * 20 = $220 and the other two should get 20 * 7 = $140 each.
