Answer:

1600.

Step-by-step explanation:

5 % = 0.05.

Let the number be x then

0,05x = 80

x = 80/0.05

= 8000/5

= 1600.

1600.
I do the math a bit differently. I actually take 80 and multiply it by 20 because 5 goes into 100 20 times.

Whats the GFC of 18 , 60 ?​
kirill [66]

Answer:

If you are reffering to GCF then the GCF would be explained like this

   Find the prime factorization of 18

   18 = 2 × 3 × 3

   Find the prime factorization of 60

   60 = 2 × 2 × 3 × 5

   To find the gcf, multiply all the prime factors common to both numbers:

   Therefore, GCF = 2 × 3

   GCF = 6

Solve the system of equations. x+2y=6; 3x-14y=8 please help
ira [324]
Let x = 6 = 2y so
3(6 - 2y) + 14y = 8 so
18 - 6y + 14y = 8 so
8y = -10 and
y =  \frac{ - 10}{8} =   - \frac{5}{4}  \\  \\ since \: x = 6 - 2y \\ 6  - 2( \frac{ - 5}{4}) = x  \: so \\ x = 6 +  \frac{10}{4} =  \frac{24}{4} +  \frac{10}{4} =  \frac{34}{4} =  \frac{17}{2}
