Let y represent the number of feet and x represent the number of minutes. Convert 22 1/2 to decimal form: 22.5
y = -22.5x
Plug in -315 for y
-315 = -22.5x
divide both sides by -22.5
14 = x
It will take 14 minutes.
Yes they are proportional to each other 25/45 =0.5 repeating itself and 15/27 is 0.55 also repeating itself
I hope this help you :) mark me brainiest if u need anything more help like this tell em
Answer:
4) x = -3 or 8
Step-by-step explanation:
We factories each algebraic expression
4) x² -5x - 24 = 0
x² - 8x + 3x - 24 = 0
(x² - 8x) + (3x - 24) = 0
x(x - 8) + 3(x - 8) = 0
(x + 3)(x - 8) = 0
x + 3 = 0, x = -3
x - 8 = 0, x = 8
x = -3 or 8
<span>Each yard is three feet, which means 8 x 3 = 24 feet. Then, you would take 24 divided by 3, which equals 8, and each piece would be 8 feet long. One foot equals 12 inches, so 12 x 8 = 96 inches, making each piece 96 inches.</span>
Answer:
1/2
Step-by-step explanation:
First, find the recipocal (or however you spell it):
2/3 = 3/2
Next, multiply:
1/3 x 3/2 = 3/6
Simplify:
3/3=1
6/3 = 2
Final product:
1/2
