Lisa has twelve fewer dimes than quarters, for a total of $11.05

1 answer:

5 0

So set up the equations
q-12=d
25q+10d=1105
plug in q-12 as d in the second equation:
25q+10q-120=1105, then simplify:
35q=1225
q=35
since there's 12 fewer dimes, we know that there's 23 dimes and 35 quarters.

Hi There!

Slope Intercept Form: y = mx + b

Point Slope Form: y - y1 = m(x - x1)

Part A:

Find the slope:

y2 - y1/x2 - x1 = m

12 - 21/3 - 6 = -9/-3 = 3

Slope = 3

Slope Intercept Form: y = 3x + 29

Point Slope Form: y - 21 = 3(x - 3)

Part B:

When scott started on Day 1 he was delivering packages every 29 minutes. By the time he reached Day 10 was delivering packages every 2 minutes. Im not entirely sure about this part.

Hope This helps :)
