Answer:
when you have two fractions that equal each other you want to solve by using cross multiply
What cross multiply is, is when you multiply diagonally so:
8/x=14/7
you would take 14*x and 8*7
14x=56 (you would then divide each side by 14)
x=4 (14/14=1, 56/14=4)
8/4=14/7
To check your work you could simplify
8/4=2
14/7=2
2=2, which is true
x=4
Hope this helps ;)
Answer: 466.56
Step-by-step explanation:
Volume = pi times radius^2 times height/3
Radius = 1/2 of the diameter
Volume = 3.24 times 6^2 times 12/3
Volume = 3.24 times 36 times 4
Volume = 116.64 times 4
Volume = 466.56
Answer:
y = -10
Step-by-step explanation:
(-7x+3y) - (-7x +10y) =-65 -(-135)
-7x + 3y + 7x -10y = 70
-7y = 70
y = -10
