Abox of markers costs $4. mr. reed spent $92 on markers. the number of boxes, b, can be found by solving the equation 4b=92.

the answer is 23

Step-by-step explanation: since you are trying to find the number of boxes, b, the first thing you do is isolate it by dividing 4b by 4 this eliminates the 4, and because you did it on one side you have to do it on the other so you work would look like this 4b/4=92/4 you equation would look like this when done b=23

65 degrees

Step-by-step explanation:

to find the base angles, subtract 50 from 180

180 - 50 = 130

since there are two base angles, divide 130 by 2

130/2  = 65

since base angles are equal, both angles measure 65 degrees

hope this helps
