1) It says he pours an equal amount into the first 7 beakers after pouring 16mL into the 8th so 70/7 = 10mL per beaker for the first 7.

2) If students rotate through 3 activites, each for 8 minutes, 3*8 = 24 minutes total. If it starts at 11:15, 24 minutes after that would be 11:39 (this represents the time they stop). If lunch starts at 12, there will be 21 minutes between the end of gym activities and the beginning of lunch.

Butter pecan: 25
Vanilla: 35
Chocolate: 50

The dotted line between 20 and 30 (butter pecan) will be nothing more than anything including 5. In this case, it is 25 counting up to 30.
The solid lines directly leading to a number will be that number, for instance, chocolate is 50.

Answer:

$d+8$

Step-by-step explanation:

Let d represent number of dolls in 2nd basket.

We have been given that a day-care center has 2 baskets of dolls. One basket has 8 dolls, and the other basket has an unknown number of dolls in it. We are asked to represent this situation in an expression.

The number in both baskets would be equal to dolls in 1st basket plus dolls in 2nd basket.

We can represent this information in an expression as:

$d+8$

Therefore, our required expression would be $d+8$ , where d represents number of dolls in 2nd basket.

When 8 is added to the number that is produced by doubling the number x, the result is equal to 8 times the number that is 5 les

Natasha_Volkova [10]

Hello. In order to solve this problem, you need to write an equation. Hence, you determine this equation:

8 + 2x = 8(x-5)
8 + 2x = 8x - 40
8 + 40 = 8x - 2x
48 = 6x
x = 8.
