The first three terms of an arithmetic sequence are as follows. - 7, - 3, 1 Find the next two terms of this sequence
Please help

Answers

Answer:

5, 9

Step-by-step explanation:

To obtain the next term in a sequence add the common difference d to the previous term.

d = a₂ - a₁ = - 3 - (- 7) = - 3 + 7 = 4

Thus

a₄ = a₃ + 4 = 1 + 4 = 5

a₅ = a₄ + 4 = 5 + 4 = 9

A copy machine can print 340 color copies every 8 minutes. Explain or show your reasoning.



A teacher printed 850 copies. How long did it take to print?

Answers

Step-by-step explanation:

340=8min

850=?(x)

340x=850×8

340x=6800

x=6800/340

x=20min

so..the teachertook 20 minute to print 850 copies

Simple:
340 copies every 8 minutes
Find copies per minute
340 / 8 = 42.5 copies/min
Now, to find out how long it took to print all 850 copies;
850 / 42.5 = 20 min.
It took 20 minutes.
Or
(850*8) / 340 = 20

to be sure

[tex]70 + 80 + 30 { = }^{?} 180[/tex]
