5. Edward has several missing assignments in his math class with a total of
274 problems to complete. His goal is to complete 4 problems this week, 6
next week, 9 the following week, and so on.
a) How many problems will he do in the 5th week?
b) If there are 9 weeks of school left, and he continues with the
pattern, will he finish the missing work? (Assume he doesn't add to
his missing work.)

they would have to work 32 hours.

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
