Answer:
9. 2a + 14
10. 7h - 70
Step-by-step explanation:
(2 x a ) + ( 2 x 7 )
(7 x h ) - ( 7 - 10 )
Answer: 1 is -17, 2 is -2, 3 is -2.5, 4 is 3, 5 is -3, 6 is -4, 7 is 2.5, 8 is -1, 9 is 4, and 10 is 2.
Step-by-step explanation:
To solve the first problem, you have to multiply both sides by 3, or 3/1.
3/1(n/3)=2(3)
3n/3=6
1n=6, or n=6.
To solve problem 2, simply divide both sides by 5.
5t/5=20/5
t=4
Hope this helps :-)
