If I were you, I would select the first equation to put in y=mx+b form so that you can substitute it in to the second one. What you do is you subtract the x from the left side and bring it over to the right and then you divide everything by 5. The y=mx+b equation is y=-1/5x-7. Then, you substitute this equation into the bottom one so you are now working only with x's. You should distribute and combine like terms. When you distribute and clean it up, at the end you should get 18/5x-14=8. You then add 14 to get 22 on the right side and then multiply that by the reciprocal of the fraction. When you multiply 22 by 5/18, you should get a reduced fraction of 55/9. You then substitute this value into either equation to get the y-value. You should get a y-value of -260/45. Your answer as an ordered pair should be (55/9,-260/45).
Yes, Dean is correct.
13% = 13/100 = 0.13
0.1 = 0.10
0.13 is greater than 0.10.
.438
rounded to nearest tenth = .4
rounded to nearest hundredth = .44
2/3 box per 1/2 minute => 2(2/3) box per 2(1/2) minute
Thus it is 4/3 box per minute
