Angad, Caroline and Sarah share some sweets in the ratio 7:4:3. Angad gets 52 more sweets than Sarah. How many sweets does Caroline get?

52 sweets

Step-by-step explanation:

Okay so first you assign variables to each person, but in this case we can just use 1 variable: x.

Angad: 7x

Caroline: 4x

Sarah: 3x

So then you see that Angad gets 52 more than Sarah: 7x-3x = 52

Simplify to get 4x = 52. Divide by 4 to then get x = 13.

Substitute x back in to get Caroline's number: 4 * 13 = 52 sweets (coincidentally the same number more that Angad gets than Sarah).

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

c is the answer
