There are 5 options. Let's figure out which ones are wrong, and why:
<span>y + y + y = y(1 + 1 + 1)
This one is correct, because of the distributive property. Another equivalent is 3y.

2a + 2b = 4ab
This one is incorrect, as you are not multiplying the numbers.

3 · (2 + x) = 6 + 3x
This one is correct, because of the distributive property

2t + 3t = 5t
This is correct, as you can add variables together as long as all the variables are the same

x + 3 = 4x
This is not correct, as 4x is 4 x's.

liq [111]

Answer:

40th customer

Step-by-step explanation:

Given that there is a promotional event

A sporting good store gave t shirt and free water bottle.

T shirt was given to 8th customer and water bottle to every 10th customer.

For the first person who should get both, he should have number as least common multiple of 8 and 10

8 = 2x2x2

10 = 2x5

Hence least common denominator = 2x2x2x5 = 40

Thus 40th customer will be the first to get both.
