A box contains 100 colored chips; some are pink and some are blue. Milton chooses a chip at random, records the color, and place
Lena [83]

The approximate number of pink chips is 40. Here's why: what you need to do is set up the problem as shown below. 12 goes above 30 because you have to know what the total number of chips chosen is in order to relate it to 100 chips. From there, all you have to do is cross-multiply and divide (or my middle school teacher used to call it fish.... I'll explain why). First you are going to draw a line from the 100 to the 12 and multiply them. then you are going to curve the line that you will draw from the 12 to the 30 and divide the product of 12 and 100 by 30. Then you will draw a line from the 30 to the X meaning that the quotient that you find from the product of 120 and 100 divided by 30 equals X.  Hope that helps.

Write a two-columm proof
Nastasia [14]

Both angles 2x+6 and 96 shown are vertically opposite angles and vertically opposite angles are always equal

so 2x+6 should be equal to 96

so 2x + 6 = 96

Now we have to solve for x here and have to get x by itself on left hand side

So first get rid of +6 by doing its opposite -6 on both sides

2x + 6 -6 = 96 -6

2x = 90

Now to get x by itself we have to get rid of 2, for that divide both sides by 2

\frac{2x}{2} = \frac{90}{2}

x = 45

Hence proved that x = 45
