Answer:
3, 6, 12, 15
Step-by-step explanation:
3/12= 4
3/9= 3
For example, let's say that you had a birth day party, and at the party, you had 11 people all ready bringing food, but you needed 28 people to bring food. And in this equation, "x" would represent the amount of people that needs to come to bring food, and that 28 would then be the total.
We then do, 28 - 11 = 17.
And therefore, there would then have to be 17 people who would have to attend to bring food for the part. (end of example).
So this above would show and model on how to use these kind of equations in a real situation in a everyday life.
27.08 I used a money converter but at least it worked (I think)
103-7 = 96 then 96/2 = 48 so we can say that Sydney is 48 and devaughn is 48+7 = 55 years old.
Therefore, Sydney is 48 years of age.
The answer is the second one, B! so we can understand how the present came to be.
