D. The 60 is subtracted from both sides because the 60 disappears from the right and decrases the value of the left
Answer:
C = 14pi units
C is approximately 43.96 units
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
C = 2*7*pi
C = 14 pi
If we approximate pi
C = 14*3.14
C =43.96 units
Answer:
1. (a) a+b=86
2. (c) 5.99a+9.99b≤600
Step-by-step explanation:
1.
a = amount of 16gb memory sticks
b = amount of 21gb memory sticks
Gary is buying a memory sticks for each of the 86 teachers. Therefore the total sum of both 16gb and 32gb memory sticks should equal 86:
a+b=86
2.
a = amount of 16gb memory sticks
b = amount of 21gb memory sticks
Each 16gb memory stick cost $5.99, and each 32gb one costs $9.99. Therefore...
5.99a = total cost of 16gb memory sticks
9.99b = total cost of 32gb memory sticks
Gary has to spent an amount less than or equal to $600. Therefore, the total sum of the costs of both 16gb and 32gb memory sticks should be less than or equal to 600:
5.99a+9.99b≤600
GCF of them is 2w.
Hope this helps :)
