X = 5y, where x > 0 and y > 0;
x - y = 200 => 5y - y = 200 => 4y = 200 => y = 200/4 => y = 50 => x = 250.
Answer:
x = p/(r-s)
Step-by-step explanation:
Collect terms and divide by the coefficient of x.

Must be 16 and 21 because we can see
30 and 70 has 10 as factor
24 and 44 has 2 as factor
12 and 30 has 2 as factor and all those factors are greater than one
Answer:
x = (2600/4000) × 100%
x = 0.65 × 100%
x = 65%
Step-by-step explanation:
The percentage equation that can be used to find the percent of books that are fiction can only be found where the number of fiction books is known and the total number of books available is known as well.
Given;
Number of fiction books = 2,600
Number of books = 4,000
let the percent of books that are fiction be x
x = (2600/4000) × 100%
x = 0.65 × 100%
x = 65%
Answer:
6
Step-by-step explanation:
This function corresponds to 'even' function, then
in order to calculate the 'x' of the vertex: (3+9)/2=6.
