Answer:
F = 1.25
Step-by-step explanation:
All you would have to do is cross multiply, so our equations starts at . We would now multiply F by 8 and 2 by 5. We now have 8F = 10. We can now divide both sides of the equation by 8 to get F = 1.25.

Answer:
see below
Step-by-step explanation:
The third table shows a relationship of y=2x.
_____
Essentially, you have to see whether the value of y/x is constant for all the values in a table. If it is not, then the relation is not proportional.
in the first table, -4/-2 ≠ -3/-1
in the second table, -4/-2 ≠ 3/1
in the fourth table, -4/-2 ≠ 6/2

Given:
In a set of 3 numbers the first is a positive integer, the second is 3 more than the first and the 3rd is a square of the second.
To find:
The equation for the given situation if the sum of the numbers is 77.
Solution:
a. Let the first number in the set is x.
The second is 3 more than the first. So, the second number is .
The 3rd number is a square of the second. So, the third number is .
Therefore, the first, second and third numbers are respectively.
b. The sum of the numbers is 77.
First number + Second number + Third number = 77
c. So, the equation in terms of x is:
Therefore, the required equation is .
d. On simplification, we get
Subtract 77 from both sides.
Therefore, the simplified form of the required equation is .
