the ratio of pens to pencils that are used by Woodlands middle school students is 3 to 2 if their is a total of 160 middle school students how many of them use pencils

Number of students that use pen= 96

Step-by-step explanation:

Giving the following information:

Ratio pens to pencil= 3:2

First, we need to calculate the proportion of pens and pencils in this middle school:

Pens= 3/5= 0.6

Pencil= 2/5= 0.4

Now, we can determine the number of students that uses pens:

Number of students that use pen= 160*0.6

Number of students that use pen= 96

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
