First solve for x in the first equation. So you'll have to substitute,
5(3x-7)=20
15x-35=20
Then add 35 to both sides.
15x=55
Divide 55 by 15.
So x = 3.66...
Then plug in 3.7 for x in 6x-8
6(3.7)-8
Its approximately 14.2
Answer:
15
Step-by-step explanation:
1st multiply the numbers: 25 × 9 = 225
2nd factor the number: 225 = √15^2
3rd apply radical rule: √15^2 = 15

The supplementary angle of 120° is 60°.
So your answer is 60 degrees.
7/18! This is because if you double both the top and bottom of 8/9 you get 16/18. Half of 18 is 9. So if we use half a yard, 9/18, and we subtract it from 16/18, we get 7/18!
