Answer:
12
Step-by-step explanation:
You need to find the least common denominator (LCD) to all the denominators of the fractions present in the equation. These denominators are (writing them in their prime factor form to make our calculations easier):
Therefore, we need to include a factor of 3, and two factors of 2 (
) in our least common denominator, so this LCD will be a perfectly divided by all three given denominators, therefore eliminating all fractions in the equation.
Our LCD is = 
Step-by-step explanation:
<h2>Answer:-</h2>
First, we need to add up the x.
We know that 4+8 = 12, so
Now, equating it to y,
Now, if I multiply 
on both sides,
I get,
Now, as 12 got cancelled , I got the final answer as
Hope it helps :)
X=y-2
2y=5x-17
Substituting for x into the second equation, we find
2y=5(y-2)-17
2y=5y-10-17
-3y=-27
y=9
So x=7
Thus, the two numbers are 7 and 9.
Hello!
Brice is standing further away from the door, because 20 metres are greater than 20 centimetres.
A lot greater, actually, because 20 metres = 2,000 centimetres.
$4/3=$1.33 per pound.
$9/8 = $1.13 per pound.
The second one is cheaper.
