Answer:
x =7
Step-by-step explanation:
Solve for x:
5 x - 10 + 65 = 90
Add like terms. 65 - 10 = 55:
5 x + 55 = 90
Subtract 55 from both sides:
5 x + (55 - 55) = 90 - 55
55 - 55 = 0:
5 x = 90 - 55
90 - 55 = 35:
5 x = 35
Divide both sides of 5 x = 35 by 5:
(5 x)/5 = 35/5
5/5 = 1:
x = 35/5
The gcd of 35 and 5 is 5, so 35/5 = (5×7)/(5×1) = 5/5×7 = 7:
Answer: x = 7

Answer:
= 2(1 - 2h)
Step-by-step explanation:
Given that:
=3(2−0.9h)+(−1.3h−4)
Simplifying:
=(6 - 2.7h) + (-1.3h - 4)
Removing brackets
=6 - 2.7h -1.3h - 4
Adding like terms (h terms and constants)
= 2 - 4h
We can take 2 common as:
= 2(1 - 2h) Required sum
I hope it will help you!
Answer:
9
Step-by-step explanation:
Less means minus, so basically X ( something ) - 9 is 0
X - 9 = 0
You add 9 on each side
X = 0 + 9
X = 9
Basically, all you're doing is the reverse, you start with 0 and do the opposite of taking away 9 which is adding nine so that you get the number:
0 + 9 = 9
Hence the number is 9
