Svetach [21]

Answer:

41 2/3 oz of water

Step-by-step explanation:

All you have to do is multiply 8 1/3 by 5.

First, lets convert 8 1/3 into an improper fraction (a fraction where the numerator is greater than the denominator):

8 1/3 = 25/3

now, we can multiply 25/3 by 5 and get 125/3, which simplifies to 41 2/3

Find the midpoint of the line segment<br> with endpoints (-4, 16) and (6, -10).
Alenkasestr [34]

Answer:

<h3>B. (1,3)</h3>

Step-by-step explanation:

<h3>What is a midpoint?</h3>

Midpoint a point equidistant from the ends of a line or the extremities of a figure.

To find the midpoint of the line segment with endpoint, use the midpoint formula.

<u>Midpoint formula:</u>

\Rightarrow: \sf{\dfrac{x_2+x_1}{2}, \dfrac{y_2+y_1}{2} }}}

y2=(-10)

y1=16

x2=6

x1=(-4)

<u>Rewrite the problem down.</u>

\sf{\left(\dfrac{6-4}{2},\:\dfrac{-10+16}{2}\right)}

<u>Solve.</u>

6-4=2

2/2=1

-10+16=6

6/2=3

<u>= (1,3)</u>

Therefore, the correct answer is B (1,3).

I hope this helps, let me know if you have any questions.

A line is parallel to y = 5x + 3 and
WARRIOR [948]

Answer:

y = 5x - 6

Step-by-step explanation:

1. In a linear equation, it is represented by y = mx + b

2. A line parallel to another has the same slope (m) but a different y-intercept (b)

3. So we know that it is y = 5x as the first half. However, we need to find the new y-intercept.

4. Let's plug in the point we know into the equation, and see what amount we are missing (the y-intercept)

5. y = 5(3)

6. y = 15, however, we know that y = 9. That's a difference of -6.

This shows us that the y-intercept is -6 making the full equation:

y = 5x - 6

We can check by putting the point back into the equation:

y = 5(3) - 6

y = 15 - 6

y = 9

This correlates with the original point, we have solved the equation.
