Answer:
is the fraction of 8th graders who are boys.
Step-by-step explanation:
Let total number of 8th graders = 
Given that, 
of 8th graders play sports
8th graders who play sports = 
Also, Given that, 
of 8th graders that play sports are boys
Number of 8th graders that play sports, and are boys = 
Hence, the answer is:
is the fraction of 8th graders who are boys.
Try this solution:
D(f): √(2-x)≥0; ⇔ 2-x≥0; ⇔ x≤2 or x∈(-∞; 2].
Answer: The width is 14m
Step-by-step explanation: The question has provided the perimeter as 60. The available clues are such that the length measures 2m more than it's width. This means whatever is the width of the rectangle, the length shall be equal to plus 2. Hence, if the width is W, the length is W + 2.
So we have,
Perimeter = 60
Length = W + 2 and
Width = W
Already the perimeter is given as
Perimeter = 2(L + W)
We can now express the perimeter as follows;
60 = 2(W + 2 + W)
60 = 2(2 + 2W)
By cross multiplication we now have
60/2 = 2 + 2W
30 = 2 + 2W
Subtract 2 from both sides of the equation
28 = 2W
Divide both sides of the equation by 2
14 = W.
Remember that the length is given as W + 2, so the length becomes
14 + 2 = 16
Therefore, the width equals 14 m.
You subtract the like terms, don't forget to distribute the subtraction sign, its 7x2+5x
