147/x=100/70 (147=100, 70 is from the percent)
(147/x)*x=(100/70)*x
147=1.4285714285714*x
147/1.4285714285714=x
x=102.9 is your answer
Step 1
Step 2
A)Find the constant of proportionality K when n = 10 books and h = 12 inches
Step 3
B) Write an equation that relates H and n by substituting for k
Step 4
C) Find the height, H of the stack of 24 books
Answer:
slope if -7/8 and y-intercept is 43/16
Step-by-step explanation:
-5+14x+16y=38
14x+16y=43
16y=43-14x
16y=-14x+43
y=-7/8x+43/16
Therefore, slope if -7/8 and y-intercept is 43/16
Try and do the Pythagorean theorem a^2 + b^2= c^2
9514 1404 393
Answer:
no
Step-by-step explanation:
For a linear equation to represent a proportion, the y-intercept must be zero. Here, the value of y for x=0 is -5, not 0.
The equation DOES NOT represent a proportional relationship.
