what is the lcd of 7/8 and 3/4 ?

4
8
16
32

8

Step-by-step explanation:

1. Rewrite your fractions to simplify: 7/8, 3/4

2. Evaluate the denominators and find the least common multiple, which is 8. LCM(8, 4) = 2^3 = 8, and you've found the LCD.

3. Rewrite the fractions to reflect the new equivalents: 7/8, 6/8

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer: x=60
