Answer:
1 2/21
Step-by-step explanation:
We start out with:
3/7 + 2/3
In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:
3/21 + 2/21
But what about the numerators? You do the same thing as before (multiplying by the other's denominator). Now we have:
9/21 + 14/21
We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:
1 2/21!

Answer:
x = -5.85
Step-by-step explanation:
Solve the equation
1)
Subtract -2.7 on both sides by doing the inverse operation.
2)
Multiply both sides by -9/2 to cancel out -2/9x, so that you can isolate "x" by itself.
3)
9.75%=9.75 / 100
=0.0975
=0.0975 / 1 × 10000 / 10000
=975 / 10000
=39 / 400
Hope this helps :)
