Rules for adding: if the bases are the same you can add them, and subtracting happens in a fraction
Answer:
22 units
Step-by-step explanation:
The perimeter of a rectangle is 2(width + length)
In this case width = 2z + 2 and length = 3z + 3
replacing everything known:
110 = 2(2z + 2 + 3z + 3)
110/2 = (5z + 5)
55 = 5z + 5
55 - 5 = 5z
50 = 5z
10 = z
Segment PQ is the same as SR = 2z + 2
Replacing z = 10
PQ = 2(10) + 2
7/2= 3 1/2, 12/5= 2 2/5, 11/7= 1 4/7, 15/4= 3 3/4
Answer:
About 4.5
Step-by-step explanation:
First, divide 28 by 3, round to closest number (2 numbers after the decimal) then take 42 divided by that number (9.33), and you get about 4.5
Hope this helped!
