Answer:
27
Step-by-step explanation:
If Fiona's age is x, Dan and Gavyn's ages respectively are x + 8 and x - 9. We can write:
x + x + 8 + x - 9 = 56
3x - 1 = 56
3x = 57
x = 19
The eldest is Dan (because x + 8 > x and x + 8 > x - 9). His age is x + 8 = 19 + 8 = 27.
Answer:
c. 24 is a solution
Step-by-step explanation:
Given equation:

To test the numbers 22, 23, 24, 25 for the solution.
Solution:
In order to test the given number for the solution, we will plugin each number in the unknown variable
and see if it satisfies the equation.
1) 

Reducing fraction to simplest form by dividing the numerator and denominator by their G.C.F.


The above statement can never be true and hence 22 is not a solution.
2) 

The fractions can no further be reduced.
The statement can never be true and hence 23 is not a solution.
3) 

Reducing fraction to simplest form by dividing the numerator and denominator by their G.C.F.


The above statement is always true and hence 24 is a solution.
4) 

The fractions can no further be reduced.
The statement can never be true and hence 25 is not a solution.
Answer:
If you are using slope intercept it is incorrect
Step-by-step explanation:
For the first part y is 2 so using y=Mx+b it’s 2=-6-5 which is not correct
Can u put a picture of the question with this so I can answer it.
