If y varies directly as x and y = 144 when x = 12, what is the value of y when x = 17?

olasank [31]

Direct variation:
$y=kx$

y=144 when x=12.
$144=12k \\ k=\frac{144}{12} \\ k=12$

y=? when x=17.
$y=12 \times 17 \\
y=204$

y=204 when x=17.

creativ13 [48]

Answer:

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3x−5=

x+2x

3x+−5=

x+2x

3x−5=(

x+2x)(Combine Like Terms)

3x−5=

Step 2: Subtract 5/2x from both sides.

3x−5−

x−

x−5=0

Step 3: Add 5 to both sides.

x−5+5=0+5

x=5

Step 4: Multiply both sides by 2.

2*(

x)=(2)*(5)

x=10
