Answer:

x=280

Step-by-step explanation:

We have, 15% × x = 42

or,

15

100

× x = 42

Multiplying both sides by 100 and dividing both sides by 15,

we have x = 42 ×

100

15

x = 280

If you are using a calculator, simply enter 42×100÷15, which will give you the answer.

The model below represents the equation 3x+2=2x-5,
Leno4ka [110]

Step-by-step explanation:

Hey there!

The equation is;

3x + 2 = 2x - 5

Shifting "2x" to left side and "2" to right side.

3x - 2x =  - 5 - 2

Simplify them to get answer.

x =  - 7

Therefore the value of x is -7.

<u>Check</u><u>;</u>

3 × -7 + 2 = 2 × -7 -5

-19 = -19 ( True ).

So, your answer is option B.
