Every fraction is just a short way to write a division.
Whenever you see a fraction, it means
the top number
divided by
the bottom number.
When you actually do the division, like with a pencil or a calculator,
the quotient you get is the decimal form of the fraction.
I won't insult your intelligence by giving you 7 divided by 25 .
I'm sure you can do that easily.
I also won't insult your intelligence by sending you to a web site.
I assume that if you were on a desert island without your phone
or any 4G coverage, you'd be able to figure out a way to divide
7 by 25.
Answer:
y = 36
Step-by-step explanation:
Given y varies directly as z and inversely as x then the equation relating them is
y = 
← k is the constant of variation
To find k use the condition y = - 18, z = 3 when x = 6 , then
- 18 = 
( multiply both sides by 6 )
- 108 = 3k ( divide both sides by 3 )
- 36 = k
y = 
← equation of variation
When x = 5 and z = - 5, then
y = 
= 
= 36
Answer:
x= 4.5
Step-by-step explanation:
90-36=54
54 divided 12 = 4.5
-12 + 9y = -57
add 12 to both sides, 9y = -45
divide 9 from both sides to isolate the y
y = -5
17/4 because you have to do 4x4 +1 which equal 17 then make that an improper fraction.
