Answer:
The two numbers are 24 and 32
Step-by-step explanation:
We can use the variable x
3x : 4x, would be a ratio of 3/4
now subtract 4 from both
3x - 4 : 4x - 4 = 5/7
3x-4 / 4x-4 = 5/7
cross multiplication
7(3x - 4) = 5(4x - 4)
21x - 28 = 20x - 20
x = 8
Two numbers are;
3x, 4x
3(8), 4(8)
24, 32
24/32 = 3/4
20/28 = 5/7
C. None of the engines are defective.
I think it is a rational number.
Equation of the table is given by
y - 210 = (280 - 210)/(4 - 3) (x - 3)
y - 210 = 70(x - 3)
y - 210 = 70x - 210
y = 70x
When x = 11, y = 70(11) = 770
Equation of the graph is given by
y = 110/2 x = 55x
When x = 11, y = 55(11) = 605
Therefore the value of y in the table is grater than the value of y in the graph by 770 - 605 = 165
