= ![\sqrt[3]{2 * 4}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%20%2A%204%7D)
= ![\sqrt[3]{2 * 2 * 2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%20%2A%202%20%2A%202%7D)
= ![\sqrt[3]{2 ^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%20%5E3%7D)
= 2.
Hope this helps!
I am going to build a chart this is best when using ratios
seniors junior total
7 4
*? *? *?
Totals 121
The way we fill out this chart is that we add the rows and multiply the columns.
So we add 7 + 4 and fill it in our chart we get 11
seniors junior total
7 4 11
*? *? *?
Totals 121
now to find the *? need to divide 121/11 to get *?
121/11 = 11
so now our chart looks like this
seniors junior total
7 4 11
11 11 11
Totals 121
Now we multiply each column
so
7 * 11 = 77
4*11 = 44
now our chart look like this
seniors junior total
7 4 11
11 11 11
Totals 77 44 121
so seniors get 77 spaces
and juniors get 44 spaces.
Answer:
a=19
Step-by-step explanation:
First we have to distribute the parenthesis; multiply (a+5) by 1/3
8=1/3*a+1/3*5
Now we just solve the equation regularly
8=1/3a+5/3
8-5/3=1/3a
6 1/3=1/3a
a=19
