Answer:

x=−12/5

Step-by-step explanation:

2(1.5x−2)=−0.5(−4x−32)

Step 1: Simplify both sides of the equation.

−2(1.5x−2)=−0.5(−4x−32)

(−2)(1.5x)+(−2)(−2)=(−0.5)(−4x)+(−0.5)(−32)(Distribute)

−3x+4=2x+16

Step 2: Subtract 2x from both sides.

−3x+4−2x=2x+16−2x

−5x+4=16

Step 3: Subtract 4 from both sides.

−5x+4−4=16−4

−5x=12

Step 4: Divide both sides by -5.

−5x−5

=12/−5

x=−12/5

Answer:

x°= 55°

Step-by-step explanation:

First, find the degrees of the larger triangle.

Since every triangle equals 180° degrees, make an equation.

60°+90°+a°= 180°

Now, add the degrees together.

120°+a°= 180°

Then subtract from both sides.

120°+a°= 180°

-120 °      -120°

a°= 60°

Now that you know the sum of all the angles, subtract 25° from 60°(which is the measure of a).

60°-25°= 35°

Now that we have the measurement of the angle from the smaller triangle inside the larger one, make an equation.

35°+90°+x°= 180°

Then, add the degrees.

125°+x°= 180°

Subtract from both sides of the equation to get the answer for the variable.

125°+x°= 180°

-125°       -125°

x°= 55°

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 3x + 1

f(-2/3) is x = -2/3

<u>Step 2: Evaluate</u>

  1. Substitute:                    f(-2/3) = 3(-2/3) + 1
  2. Multiply:                        f(-2/3) = -2 + 1
  3. Add:                              f(-2/3) = -1
