Kryger [21]3 years ago

Answer: x=0

<u>Combine like terms: 5x + 3x = 8x</u>

<u></u>8x = 7x<u></u>

<u></u>

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

<u>Add '-7x' to each side of the equation</u>

<u></u>8x + -7x = 7x + -7x<u></u>

<u></u>

<u>Combine like terms: 8x + -7x = 1x </u>

<u></u>1x = 7x + -7x<u></u>

<u></u>

<u>Combine like terms: 7x + -7x = 0 </u>

<u></u>1x = 0<u></u>

<u></u>

<u>Divide each side by '1'.</u>

<u></u>x = 0<u></u>

taurus [48]

Two triangles are similar if they are the same, except one is bigger and one is smaller. Also, their angles are all the same. A career that uses similar triangles could be a mathematician, or a math teacher. Both of these need to be able to understand simple concepts like similar triangles to teach to their victims.

What percent of 120 is 28.8
12345 [234]

Answer:

24

Step-by-step explanation:

Step 1: We make the assumption that 120 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=120$.

Step 4: In the same vein, $x\%=28.8$.

Step 5: This gives us a pair of simple equations:

$100\%=120(1)$.

$x\%=28.8(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{120}{28.8}$
