The question says kilograms every minutes, so it's C or D. The answers on A and B same
Answer:
<u>6</u>
10
=<u>3</u>
5
Step-by-step explanation:
3/5 you just need to divide
The first step is to combine like terms. So u would do 2-6. You then get -4 then u just bring everything else down. So now u should have this :
8x -4 = 4x + 8 + 3x
Now you do the same thing to the other side. U combine like terms which in this case are 4x and 3x. So u just do 4+3 which is 7 so now u have 7x. So now ur equation would be:
8x -4 = 7x +8
Now u do the inverse of 7 which would be -7 and u do that on both sides. So it would look like this :
8x -4 = 7x + 8
-7x. -7x
So now 7 and -7 cancel each other other and 8 -7 is 1 so now u have one x. So ur equation would now look like this:
1x -4 = 8
Now u do the inverse of negative 4 which is +4. So you would add 4 on both sides on both sides. Like shown:
1x -4 = 8
+4 +4
So u just add 8 + 4 which is 12. Now since anything times 1 is itself ur answer will be X=12

Find a common multiple in between the denominators.
10 and 3 and 5 -> the least common multiple is 30.
Change all the denominators to 30 by multiplying the top and bottom by the same number.
9/10=27/30
1/3=10/30
1/5=6/30
Subtract!
27/39-10/30-6/30=11/30
The answer is 11/30
Hope this helps!
