Answer:

x=12

Step-by-step explanation:

we know that

An equilateral triangle has three equal sides and three equal interior angles (each angle measures 60 degrees)

In this problem we have a equilateral triangle

so

AB=BC=AC

Equate AB=BC

(4x-10)=(3x+2)

solve for x

(4x-3x)=(10+2)

x=12

<u><em>Verify the length of each side</em></u>

AB=4x-10=4(12)-10=38\ units

BC=3x+2=3(12)+2=38\ units

AC=5x-22=5(12)-22=38\ units

therefore

AB=BC=AC ---> is correct

An electric company charges a certain rate per kilowatt-hour (\text{kWh})(kWh)left parenthesis, start text, k, W, h, end text, r
Studentka2010 [4]

Step-by-step explanation:

The equation is given by :

63.25=800r+3.50

Here,

63.25 is the electric company charges

3.5 is an administrative fee

800 is charge per kilowatt hours

r is rate per kilowatt hour

In this proble, we need to tell that what does r represents. Hence, r shows kilowatt per hour.

We can solve it as follows :

63.25-3.5=800r+3.50-3.50 (Subtracting 3.50 to the both sides)

59.75=800r

r=\dfrac{59.75}{800}\\\\r=0.0746

Help please?!?!?!?!?!?!
svp [43]

slope is change in y over change in x

 use 2 points from the table so -3,-21 and -6,-39

change in Y: -39 - -21 = -18

change in x = -6 - -3 = -3

slope = -18/-3 = 6

slope = 6
