.22×250=you will get 5500 but remember you plug in the decimal and move it two time

which it is 55.00 so its 55

How do I find X in this problem

pogonyaev

You know that BC is congruent to x so you need to solve for x using the ratio:
$\frac{12}{24}=\frac{x}{BC}$

So then we need to find BC.

We know:
$A=\frac{base \times height}{2}$
$28=\frac{BC \times 7}{2}$
Therefore BC =8

Then:
$\frac{12}{24}=\frac{x}{8}$
$x=8 \times \frac{12}{24} = 4$
