Hello!
First you have to find how many sections of blue ribbon makes 1 meter
1/5 * 5 = 1
It takes 5 sections of blue ribbon to make one meter of blue ribbon
Multiply this by the sections of red ribbon
1/2 * 5 = 2.5
The answer is 2.5 meters of red ribbon for every meter of blue ribbon
Hope this helps!
4y>12
y>12/4
y>3
5>3
6>3
7>3
Therefore, the solution is {5,6,7}
t is the number of hours Lamar worked as a tutor
We know that he worked for 92 hours total, so he worked 92-t hours as a waiter.
So his earnings are: 7t + 8(92-t) = 736 -t dollars
This expression seems logical as if Lamar worked 0 hours as a tutor and 92 as a waiter his earnings would be 8*92 = 736
If he worked as a tutor for 92 hours it would be 7*92= 644
736-92= 644
So our expression seems to be working.
Is there anything else on the paper that can help me with that? like any questions at the top?
