Answer:

Step-by-step explanation:

-2/3x+9=4/3x-3=

x=6

JulijaS [17]3 years ago

Answer:

x=6

Step-by-step explanation:

We have the equation:

-\frac{2}{3}x+9=\frac{4}{3}x-3

First, we can remove the fractions by multiplying both sides by 3. Therefore:

3(-\frac{2}{3}x+9)=3(\frac{4}{3}x-3)

Distribute:

-2x+27=4x-9

Subtract 27 from both sides:

-2x=4x-36

Subtract 4x from both sides:

-6x=-36

Divide both sides by -6:

x=6

Hence, the value of x is 6.

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $24 monthly fee
JulsSmile [24]

Answer:

600 minutes

Step-by-step explanation:

If we write both situations as an equation, we get:

y1 = 24 + 0.15x

<em>y1 </em><em>:</em><em> </em><em>total </em><em>cost </em><em>paid </em><em>in </em><em>first </em><em>plan</em>

<em>x </em><em>:</em><em> </em><em>total minutes </em><em>of </em><em>calls</em>

y2 = 0.19x

<em>y2 </em><em>:</em><em> </em><em>total </em><em>cost </em><em>in </em><em>second </em><em>plan</em>

<em>x:</em><em> </em><em>total </em><em>min</em><em>utes </em><em>of </em><em>call</em>

We are now looking for the situation where the total cost in the two plans is equal, so

y1 = y2

this gives

24 + 0.15x = 0.19x

<=> 0.04x = 24

<=> x = 600
