Find the measure of angle A
Gre4nikov [31]

Answer:

21 degrees

Step-by-step explanation:

Triangles have a total angle of 180 degrees.

This makes our equation:

3x+3+4x+135=180

Subtract 135 from both sides and combine like terms

7x + 3 = 45

Subtract 3 from both sides

7x = 42

Divide both sides by 7

x = 6

Plugging the number in:

3x + 3 =

3(6) + 3 =

21

What is 3/8<br> as an equivalent fraction with the LCM as the denominator?
tino4ka555 [31]

Answer:

3/8 = 9/24

Step-by-step explanation:

So here we have a basic multiplication problem and finding the LCM of 8 and 3. The first step in this problem is finding the LCM of 3/8. The LCM of 3 and 8 is 24. So yay! we have the bottom half of our answer!

Ex.-

The LCM of 8 and 3 is 24.

So now we have to find an equivalent fraction. Since we already know that 8 (the denominator in the original equation) can be multiplied by 3 to equal 24, we use 3 (the numerator in the original equation) and multiply it by itself to get an equivalent fraction.

Ex.-

8 x 3 = 24

3 x 3 = 9

Now that we have our numerator and denominator, all we have to do now is put them together to get our answer.

Ex.-

9/24 (answer) = 3/8 (original equation)

Hopefully I could help! :)

A large cube has a volume of 1 cubic unit. A small cube has a volume of 1 27 of a cubic unit. What is the difference between the
ExtremeBDS [4]

Given:

Volume of Large cube = 1 cubic unit

Volume of small cube = \dfrac{1}{27} cubic unit

To find:

The difference between the edge length of the large cube and the edge length of the small cube.

Solution:

Let the edges of large and small cubes are a_1 and a_2 respectively.

We know that, volume of a cube is

V=(edge)^3

Volume of Large cube = 1 cubic unit

(a_1)^3=1

Taking cube root on both sides, we get

a_1=1

So, edge of large cube is 1 unit.

Volume of small cube = \dfrac{1}{27} cubic unit

(a_2)^3=\dfrac{1}{27}

Taking cube root on both sides, we get

a_2=\dfrac{1}{3}

So, edge of large cube is \dfrac{1}{3} unit.

Now, difference between them is

d=a_1-a-2

d=1-\dfrac{1}{3}

d=\dfrac{3-1}{3}

d=\dfrac{2}{3}

Therefore, the difference between the edge length of the large cube and the edge length of the small cube is \dfrac{2}{3} unit.

I'm so confused can someone help me
jenyasd209 [6]
3/2(x - 10 ) = 1/2 x + 5
expand by using distributive property
3/2 x - 15 = 1/2 x + 5
subtract (1/2 x ) on both sides
x - 15 = 5
add 15 on both sides
x = 20

answer
C. x = 20
