The third option is the correct answer

The correct equation is,2(s - 12) + s =87

s= 37

Step-by-step explanation:

It is given that Ara and Evalyn are collecting stamps

Ara has twice as many stamps as 12 less than the number of stamps Evalyn has.

Together they have total 87 stamps.

To find the correct equation

Let s be the number of stamps in Evalyn.

The number of stamps in Ara = 2(s - 12)

They together have 87 stamps

Therefore the equation become,

2(s - 12) + s = 87

To find the value of s

2(s - 12) + s = 87

2s - 24  + s= 87

3s = 111

s = 37

Therefore the correct answer is 3rd option.

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
