To get 2.8 from 0.1 you have to multiply by 28. So 28 tenths.
Which leaves 0.06 which is 0.01 times 6. So 6 hundredths
The answer is 3(5x+2) i hope this helps you.
There is no X But Y is (0,5)
1/2 is equivalent to 2/4 because,
2(1/2) = 2/4
So as you can see if you multiply the numerator(top) and the denominator(bottom) by the same number, you get an equivalent fraction! In my example you can see that I multiplied both by 2.
