Answer:
the third one
Step-by-step explanation:
Answer:
<h2>VU=16</h2><h2>x=2</h2>
Step-by-step explanation:
lets solve the problem 7x+2=3x+10
subtract 3x from 7x
4x+2=10
subtract 2 from 10
4x=8
divide both sides by 4
x=2
to find VU plug in 2 for x so...
3(2)+10
6+10
16
I hope this helped you :)
X=the number we have to find.
This expression "2(x+9)" is when the sum of a number and nine is doubled.
If the result is seven less than the number, we will have: x-7
We can suggest the following equation:
2(x+9)=(x-7)
2x+18=x-7
2x-x=-7-18
x=-25
answer: the number would be: -25.
The answer would be 39.78
