Bob has 120 beads

1 answer:

4 0

Bob has 10 green beads you can show this by dividing 120 by 4 and that then leaves 30 beads which is 1/4 of the original amount of beads. Now knowing that Bob has 30 beads you put it into an equation with x over 30 equal to 2/3 that then makes you able to see that if you multiple the denominator by 10 you get 30 so you do the same to the numerator causing x to be 20 and that is the amount of the red beads leaving 10 beads to be green.

SOLUTION:

Step 1:

In this question, we are given the following:

What is the midpoint of a line segment with the endpoints (-4,-3) and (7,-5)?

A. (-3.5, 1)

B. (1.5,-4)

C. (-4,1.5)

D. (1.-3.5)

Step 2:

The midpoint of a line segment with the endpoints (-4,-3) and (7,-5) is:

$\begin{gathered} (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\ =\text{ (}\frac{-4+7}{2},\frac{-3+(-5)}{2}) \\ =\text{ (}\frac{3}{2},\frac{-8}{2}) \\ \end{gathered}$
