2 1/4 you add them together and keep the fraction
If we call the number x, we can write an equation:
x + 12 = 3x - 32
and now we can solve
- x
12 = 2x - 32
+ 32
44 = 2x
÷ 2
22 = x
So your answer is 22, I hope this helps!
Answer:
<em>The sample size 'n' = 721</em>
<em>Number of cars 'n' = 721</em>
Step-by-step explanation:
<u><em>Explanation</em></u>:-
<em>Given Population proportion 'p' = 0.40</em>
<em>Given Margin of error = 0.03</em>
<em>90% of level of significance </em>
<em> </em><em></em>
<em>The Margin of error is determined by</em>
<em></em><em></em>
on calculation , we get
0.03√n = 0.8058
squaring on both sides , we get
n = 721.45≅721
<u><em>conclusion</em></u>:-
<em>The sample size 'n' = 721</em>
<em>Number of cars 'n' = 721</em>
Answer:
w = -7/6 u
Step-by-step explanation:
The independent variable is in the equation, we solve for the dependent variable
So we solve for w
4u + 8w = -3u + 2w
Subtract 2w from each side
4u + 8w-2w = -3u + 2w-2w
4u+6w = -3u
Subtract 4u from each side
6w = -3u-4u
6w = -7u
Divide by 6
6w/6 = -7u/6
w = -7/6 u
