The last set (choice D) is a subset of given set B.
The other 3 choices are wrong.
Given:
Triangle
height 14 inches
area 245 inches square
Formula in finding the area of a triangle is:
Area = (height * base) / 2
The base is missing, so we need to compute its value using the given figures.
245 = (14 * b) / 2
245 * 2 = 14b
490 = 14b
490/14 = b
35 = b
The base is 35 inches.
So to start you will need to divide by -5 then -5 divided by -5 cancelle
Answer: 27 dogs were seen at the clinic on monday.
27/45 = 0.6
0.6 = 60%
4(x-1)=6 you start by dividing the whole equation by 4, so
x-1=6/4 simplify, x-1=3/2 then you add 1 to the whole equation
x=1 and 3/2 or x=5/2
