Answer:
Step-by-step explanation:
2. 2(3x+4)=10
6x+8=10
6x+8-8=10-8
6x=2
x= 1/3
3. 2x + 7 = 5x + 16
7 + 2x = 5x + 16
7 + 2x = 16 + 5x
7 + 2x + -5x = 16 + 5x + -5x
7 + -3x = 16 + 5x + -5x
7 + -3x = 16 + 0
7 + -3x = 16
7 + -7 + -3x = 16 + -7
0 + -3x = 16 + -7
-3x = 16 + -7
-3x = 9
x = -3
4. x/3-8=-2
x/3=6
x=18
5. 3x-6=-12
3x-6+6=-12+6
3x=-6
x=-2
sorry but i cannot solve 1 or 6 because i am quite stupid
Both expressions equal 5 when substituting 2 for x because the expressions are equivalent. Hope this helped :D
As te car gets older the value depreciates because it gets used and put through rough roads or accidents. the newer the car is the better shape it is in and the higher value it would have.
Answer:2.7=n
Step-by-step explanation:
n+27=11n
Move the variable to one side so subtract n
27=10n
Divide by 10
2.7=n
I'm not sure if this what you were asking for
The answer to this question would be: <span>The new survey’s margin of error will be between 50% and 100% the size of the original survey’s margin of error.
A bigger sample will result in a narrower margin of error which is a good thing because your data will become more accurate. But twice size will not improve the margin into the half. It definitely became lower than 100% though
</span>
