(X+4)(X-4) is the LCD because you just have to look at the denominators and see what factors or values are not already part of your LCD.
First move the 4y to the right and the 1 to the left:
4y=5x-1
Then divide everything by 4:
y=5/4 x - 1/4
Answer:
Original Price= $20
Sales Price= $20*0.80= $16
Answer:
88.83
Step-by-step explanation:
To find the mean of a set of numbers is to find the average a set of numbers.
To solve for the mean you have to add all of the values together and divide that sum by the number of values there are.
Ex. 81, 97, 99, 89, 91, 76
81 + 97 + 99 + 89 + 91 + 76 = 533
533 / 6 = 88.83

(number of values)
Step-by-step explanation:
y - 4x = 3
Writing in slope intercept form that is y = mx + c
y = 4x + 3
Hope it will help :)
