20%*650g=
.
Therefore, 20% of 650g is 130g.
Just substitute each number in for the variables: 9 for m and 3 for n.
2m+2n
= 2(9)+2(3)
= 18+6
= 24
Answer:
The answer is X = 18
Step-by-step explanation:
2x/3 - 7 = 5
Multiply both sides if the equation by 3 : 2x - 21 = 15
Move the constant to the right hand side and change its sign : 2x = 15 + 21
Calculate 2x = 15 + 21
2x = 36
Divide both sides of the eqaution by 2 : 2x = 36
x = 18
Answer X = 18
