Answer:
10
Step-by-step explanation:
When we simplify we get 
Then we continue to factor to get: 
We then see that we can factor 
into 
we then do the prime factorization of 847, which i think is, 
. we have to find the numbers that multiply to 847 and then plug them into z+5, 3x=1,2y+7.
It has to be a positive, non-negative integer, right?
We also see that 3x+1=11 so we see that x=10/3 (which wont work).
So 3x+1=7, so x=2.
So 11 has to be in another term. It has to be in 2y+7=11 so y=2
for the last term we get z+5=11 so z=6
2+2+6=10
Hope this helps and if you want please consider giving me brainliest. :)
Answer:
10ac
Step-by-step explanation:
We have been given the expression a · c · 5 · 5
We can multiply 5 with 5 and get 25.
Thus, the expression becomes
a · c · 5 · 5= ac25
We can rewrite the expression using commutative property
25ac = 25ca
Therefore, the given expression is equivalent to 25ac and 25ca.
Hence, 10ac is not the correct form.
First option is correct.

Answer:
let say the number is x, then 30x÷100=78, x=260...from this we can calculate 95 percent of 260 which is equal to 247
