Answer:

1 3/4 or 1.75

Step-by-step explanation:

An easy way to do this is to convert to decimals

1/4 = 0.25

2/4 = 0.5

3/4 = 0.75

Now, for the numbers for this problem.

2 3/4 would be equal to 2.75

3 1/2 would be equal to 3.5

Add those two numbers together and you get 6.25

Subtract that from 8 and you get 1.75 or 1 3/4

Answer:

The equation of the line is $y = 34\cdot x + 168$ .

Step-by-step explanation:

According to Analytical Geometry, we know that any equation of the line can be determined by knowing two distinct points on Cartesian plane. From statement we get that:

$y(15\,h) = 678\,kg$ (1)

$y (25\,h) = 1018\,kg$ (2)

By applying the definition of the equation of the line, we form this system of two linear equations with two variables:

$15\cdot m + b = 678$ (3)

$25\cdot m + b = 1018$ (4)

By algebraic mean we get the following solution:

$m = 34\,\frac{kg}{h}$ and $b = 168\,kg$

And the equation of the line is $y = 34\cdot x + 168$ .
