1. you and your friend are shopping for painting supplies. your friend wants five bottles of paint and one set of paint brushes. you want seven bottles of paint and two sets of paint brushes. each bottle of paint costs $3.69. if you and your friend’s total cost is $51.69, what is the cost of one set of paint brushes?

First, add to find out how many bottles of paint in all : 5 + 7 = 12
Second, multiply the number of bottles by the price : $3.69 x 12 = $44.28 Third, subtract the cost of the paint from the total cost :
$51.69 - $44.28 = $7.41
Fourth, add to find hot how many sets of paintbrushes : 1 + 2 = 3
Divide the 3 by $7.41 = $2.47
One set of paintbrushes is $2.47

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
