m<1 = m<4 by vertical angles theorem
3x + 10 = 4x - 15
-1x = -25
x = 25
m<1 + m<7 = 180 if parallel alternate interior angles supplementary
3x + 10 + m<7 = 180
3(25) + 10 + m<7 = 180
75 + m<7 = 180
m<7 = 105°
Hope this helps! ;)
Answer:
75
Step-by-step explanation:
86+79+68+83=316
391-316=75
Ok so if 1200 total pens and 60 were taken that's a ratio of 1200/60=20
out of 60pens 4 didn't work, again ratio is 4/60=1/15 so about 1/15 of the pens didn't work.
so we have 1200pens * 1/15broken ratio = 80 pens or we can say
20*4=80pens won't work from 20 groups of 60 and 4 out of 60 not working is 20*4=80 not working from total batch of 1200.
hope this helps you some! thank you!!!!!!!!!
The answer is 24. To get from one term to the next, you have to find the difference. To get from 52 to 45, you minus 7. It is the same with the other terms. So 31 - 7 = 24
Answer:
First option: (Substitute)
2x+3 (x+1.5) = 12
