Answer:
8 hours for math and science each
Step-by-step explanation:
4 x 8 = 32
3 x 8 = 24
32 + 24 = 56 hours
- You need to keep what you multiply, (ex. 8), the same as you work through this problem.
- Such as this problem, sometime the best methods are to just guess and check. This means to think of a number that is reasonable and try it. For example, if you try 5 and you see it is too low, go higher. Keep doing this and you would have got to 8 eventually.
To find the value of x, isolate the x first,
5x + 6 = 2x +15
Subtract 6 to both sides because whatever you do on one side you would always to on the other side.
5x = 2x + 9
Subtract 2x from both sides
3x = 9
Divide to isolate the x
x = 3 is your answer
Answer:
![7\frac{1}{8}](https://tex.z-dn.net/?f=7%5Cfrac%7B1%7D%7B8%7D)
Step-by-step explanation:
Multiply across.
![(7\frac{1}{6})(\frac{3}{4})=7\frac{3}{24}](https://tex.z-dn.net/?f=%287%5Cfrac%7B1%7D%7B6%7D%29%28%5Cfrac%7B3%7D%7B4%7D%29%3D7%5Cfrac%7B3%7D%7B24%7D)
Then Simplify.
![7\frac{3}{24}=7\frac{1}{8}](https://tex.z-dn.net/?f=7%5Cfrac%7B3%7D%7B24%7D%3D7%5Cfrac%7B1%7D%7B8%7D)

× ![\frac{x}{968}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B968%7D)
Solve for x,
26 × 968 = 25,168
25,168 ÷ 106 = 238votes.
