Y = kx is the direct variation equation.
Use the x and y given to find k. After finding k use it to write a new equation.
120=k*50
Divide by 50 on both sides
120/50=k 12/5=k
y = (12/5)(40) y=96
If its an improper fraction thet u will put the numerator in the house and the denominator outside. for an example 11/5.... the problem would now be 5 divided by 11. once you find the quotient of the problem you will also find the mixed number which is the simplest form of a fraction

Answer:
r = 4/(x+y)
Step-by-step explanation:
rx + ry = 4
Factor out r
r ( x+y) = 4
Divide each side by (x+y)
r ( x+y) /(x+y) = 4/(x+y)
r = 4/(x+y)
10.
50+(2x)=20+(5x)
-20 -20
-2x -2x
30=3x
divide both sides by 3
10=x
Answer:
the value of x is 7.
Step-by-step explanation:
2+19=21
21÷3=7
Check:
3×7=21
21-2=19
Therefore, 7 is the answer.
