The solution is subtract4.7x on both sides. Then you get -2.2x=7.7. Divide 7.7 by -2.2 and you get x= -3.5
Answer:
$8.75 is your answer.
Step-by-step explanation:
What you do is you multiply 1.25 by 7.
<em>1.25 x 7 = $8.75</em>
$8.75 is your answer.
To work out the LCM, we need their prime factors. So:
2 is simple 2 x 1.
7 is also 7 x 1.
13 is also 13 and 1.
They all have in common "1" - so we keep that aside as 1 figure, rather than 3.
We still have the 2, 7 and 13 leftover.
We then multiply the 1 with the other figures.
So 1 x 2 x 7 x 13 is our answer.
Which is = 182.
