A. 5x and 2y
B. 3 and x
C. 5x and x
D. 4
Answer:
-4
Step-by-step explanation:
negative plus a negative means add
You add the number then keep the negative sign
The answer in simplest form is 1/4.
B is the answer because you have to math it
#22. We are given that y = 1/4. So, we want to plug this value into the expression 15/y:
15/(1/4)
When you divide by a fraction, you should follow the rule “flip the guy and multiply”. Basically, 15/(1/4) = 15 * 4 = 60.
The answer for #22 is (D).
#23. We can use a proportion:
(The shaded area)/(entire circle area) = (360 - 60)/360
But, we don’t have to find the areas of the region and circle; we can just solve the fraction:
(360 - 60)/360 = 300/360 = 30/36 = 5/6
The answer for #23 is (A).
