Printer A can print 30 pages per minute. Printer B can print 40 pages per minute. Printer B begins printing 3 minutes after Prin
ter A begins printing. Both printers stop printing 10 minutes after Printer A started. Together, how many pages did the two printers print?
1 answer:
Printer A prints for 10 minutes, so prints
... (30 pages/minute)×(10 minutes) = 300 pages
Printer B prints for 7 minutes, so prints
... (40 pages/minute)×(7 minutes) = 280 pages
At the end of 10 minutes, the two printers will have printed
... 300 pages + 280 pages = 580 pages

✔ 5 + 2a – 7
.
Second,
✔ substitute
8 in for the variable, a.
Third,
✔ simplify
by using
✔ order of operations
The answer is
✔ 14
Slope = (4 - 2)/(-6 - 2)= 2/-8 = -1/4
y = mx + b
2 = -1/4(2) + b
2 = -1/2 + b
b = 5/2
equation
y = -1/4x + 5/2
4y = -x + 10
x + 4y = 10
answer
<span>A) x+4y=10</span>
I’m most sure that the answer is A.
