Answer:
Add 5 to both sides
Step-by-step explanation:
x-5=16
+5 +5
x=21
√(1.1) = 1
√9/16 = √(3.3 / 4.4) = 3/4
The formula you would use here comes from geometry as you studied circles. In our case, 4(4+5)=3(3+x). When we simplify that we get 36=9+3x, and 3x = 27 so x = 9.
Answer: 20 students each year
Step-by-step explanation:
60+20= 80
80-60=20
you can do 80 minus 60 and get 20
then to double check you can add 60 and 20
