Answer:
Thus # 2 is correct (5 (y + 4))/2
Step-by-step explanation:
Simplify the following:
(5 y (y^2 - 16))/(2 y (y - 4))
(5 y (y^2 - 16))/(2 y (y - 4)) = y/y×(5 (y^2 - 16))/(2 (y - 4)) = (5 (y^2 - 16))/(2 (y - 4)):
(5 (y^2 - 16))/(2 (y - 4))
y^2 - 16 = y^2 - 4^2:
(5 (y^2 - 4^2))/(2 (y - 4))
Factor the difference of two squares. y^2 - 4^2 = (y - 4) (y + 4):
(5 (y - 4) (y + 4))/(2 (y - 4))
Cancel terms. (5 (y - 4) (y + 4))/(2 (y - 4)) = (5 (y + 4))/2:
Answer: (5 (y + 4))/2
Answer:
3×4×5 =60
Step-by-step explanation:
3 and 5 are prime but there is no commeon factor among the three numbers so you directly multiply 3 4 and 5.
Answer:
$125
Step-by-step explanation:
You can write an equation from the problem statement:
$80 = 0.64 × (total cost)
This is solved by dividing by 0.64.
$80/0.64 = $125 = (total cost)
_____
Of course, you know that ...
64% = 64/100 = 0.64
Both fractions are read as "sixty-four hundredths."
Answer:
Example 2 Evaluate 5x2 − 2( y + 1) + 9 when x = 2 and y = 1. 5x2 − 2( y + 1) + 9 = 5(2)2 ... In this lesson, you will. ○ use addition or subtraction to solve equations. ○ ... So, the value x = 4 is a solution of the equation x + 3 = 7.
