Answer:
4261
Step-by-step explanation:
2 times 4261= 8522
If you got confused on the first 2 divided by 2 it 1 the same has the last one but I use the 1 to add on 5 that = 6
Answer:
q=4/3
Step-by-step explanation:
simplify the right side, to 5/3
5/4q=5/3
multiply 4/5 on both sides
q = 5/3*4/5
q = 4/3
Answer:
y=-12
Step-by-step explanation:
-2(18-3y)=7y+2y
-36+6y=9y

Answer: She would require 16 ml cover 240cm^2 of her skin
Step-by-step explanation:
Let m represent the milliliters of sunscreen required to cover her skin.
Let a represent the area of her skin that was covered. She assumes the the relationship between milliliters of sunscreen and the area is proportional. Introducing the constant of variation, k, the expression becomes
m = ka
She uses 3 ml to cover 45cm^2 of her skin. Therefore,
3 = k × 45
k = 3/45 = 1/15
The expression becomes
m = a/15
The milliliters of sunscreen that Kelsey needs to cover 240cm to the power of 2 of her skin would be
m = 240/15
m = 16 ml
I believe the answer should be B. Because of the standard circle equation.
