19 - 34 which is 15/2= 7.50 dollars each on snacks
Ok so you do 900 ÷ 10 which = 90 and 90 x 10 = 900 so the answer is 90
Answer:
![47x^3\sqrt{5x}](https://tex.z-dn.net/?f=47x%5E3%5Csqrt%7B5x%7D)
Step-by-step explanation:
The objective is to combine the terms to make one radical, so therefore we know that we will have to take a
out of the second radical
.
If we divide 180 by 5, we will get 36, so now we have
×![\sqrt{36}](https://tex.z-dn.net/?f=%5Csqrt%7B36%7D)
can be simplied into just 6.
So now the expression becomes
![-\sqrt{5x^7}+8x^2*6 \sqrt{5x^3}](https://tex.z-dn.net/?f=-%5Csqrt%7B5x%5E7%7D%2B8x%5E2%2A6%20%5Csqrt%7B5x%5E3%7D)
Then we can further simplify by moving the
into the radical to get two common terms with
.
, so we now have
![-\sqrt{5x^7}+ 8\sqrt{x^4} *6 \sqrt{5x^3}](https://tex.z-dn.net/?f=-%5Csqrt%7B5x%5E7%7D%2B%208%5Csqrt%7Bx%5E4%7D%20%2A6%20%5Csqrt%7B5x%5E3%7D)
So then we can combine the two radicals to get the expression to
![-\sqrt{5x^7}+48\sqrt{5x^7}](https://tex.z-dn.net/?f=-%5Csqrt%7B5x%5E7%7D%2B48%5Csqrt%7B5x%5E7%7D)
We now see that we have two terms with a common radical, and coefficients of -1, and 48.
That allows us to simplify further to
![47\sqrt{5x^7}](https://tex.z-dn.net/?f=47%5Csqrt%7B5x%5E7%7D)
Here, we can take out
, which is
, and get the final simplied form to be
![47x^3\sqrt{5x}](https://tex.z-dn.net/?f=47x%5E3%5Csqrt%7B5x%7D)
Hope this helped.
1/10=5/x+8
Cross multiply
1•x+8=10•5
x+8=50
Subtract 8 from both sides which will give you x=42
You can easily use a fraction 975/9 divide by 3, 325/3= 108.33333
