B is the correct answer. To find out why it is, we can simply put 2,800, the whole, as 100% and 6.2 into x=6.2. The left sides of both of them have the same units, and both right sides have the same units, so we can do something such as 2800/x=100%/6.2%. Then, you simply solve for x.
STEPS:
2800/x=100/6.2
<span>(2800/x)*x=(100/6.2)*x - </span>we multiply both sides of the equation by x
<span>2800=16.129032258065*x - </span>we divide both sides of the equation by (16.129032258065) to get x
<span>2800/16.129032258065=x </span>
<span>173.6=x </span>
<span>x=173.6</span>
2b is basically 2 * b. When a number (called the coefficient) and a variable come together they multiply.
Answer: x = -12 is the correct answer
Step-by-step explanation: the moderator that deleted this if is so wrong then just tell me why is wrong if you are so smart.
We have the expression

We can already simplify x because it's both on the numerator and denominator

Now we can simplify 425/25 = 17

Remember that

Then

The final result is
