Answer: x = 24

Step-by-step explanation:

3/4 (x/4 + 8) - x/2 +2 = 3/8 (4-x) - x/4

3x/16 + 6 - x = 3/2 - 3x/8 - x/4

collect like term

3x/16 - x+ 3x/8 +x/4 = 3/2 -6

3x-16x+6x +4x / 16 = 3-12 / 2

-3x/16 = -9/2

cross multiply

-6x = -144

Divide bothside by -6

-6x/-6 = -144/6

x = 24

An angle measures 32° more than the measure of its supplementary angle. What is the measure of each angle?
ValentinkaMS [17]

Answer:

29°; 61°

Step-by-step explanation:

Let one angle  = x°

Other angle = (x + 32)°

x + x + 32 = 90   {given they are complementary}

2x + 32 = 90

2x = 90 -32

2x = 58

x = 58/2

x = 29

One angle  = 29°

Other angle = 29 + 32 = 61°

Find the area of a circle givin the diameter of 12. Use 3.14 for pi.​
valina [46]

Answer:

113.04 units^2

Step-by-step explanation:

The area of a circle can be found using:

a=\pi r^{2}

First, we need to find the radius, since we have the diameter.

<u />

<u><em>Radius</em></u>

The radius is half the diameter, or

r=d/2

We know the diameter is 12, so we can substitute that in

r=12/2                <em>Divide </em>

r=6

<u><em>Area </em></u>

Now we know the radius and can substitute it into the area formula

a=\pi r^{2}

a=\pi 6^2                 <em>Solve the exponent </em>

a=\pi 36

Substitute 3.14 in for pi

a=3.14*36                   <em>Multiply </em>

a=113.04

We aren't given a specific unit, so we can say the area is

113.04 units^2
