Question

Bella is baking 34 cookies for the holiday party tonight. She baked 18 before leaving for school and will bake the rest when she returns home.

Which equation shows how many cookies Bella will bake when she returns home?

a: 18 = x − 34
b: 34 = 18x
c: 34 = x − 18
d: 34 = x + 18

Answer 1

Answer: d: 34= x + 18

Step-by-step explanation: 34 is the total, and she already made 18. So this means that it would be 34-18=x. OR 18+x=34 which can also be written as 34=18+x

Answer 2

d: 34= x + 18

Explanation:

We are looking to create an equation for the total number of cookies Bella will bake when she returns home. Let x be equal to the number of cookies she'll bake when she returns.

It is given that she will be cooking 34 cookies in total, so however many cookies she bakes will be equal to 34 (34 = ___).

Next, it's given that she already baked 18 cookies. We will use addition to add the 18 cookies to the number of cookies she will bake.

34 = x + 18

d: 34 = x + 18
