2. x represents the amount of apples in each bag
3. I would do it by adding: 28 + 4
Because: If Lin bought 4 bags of apples that each have the same amount inside, and after she ate one apple from each bag there were 28 apples left in total then: 28 + 4 = 32 (the total amount of apples she had at the beginning). To find how many apples she had in each bag (which would be the value of x):
32/4 = 8
x = 8
Lin bought 4 bags of apples with 8 apples in each bag.

Andre came up with the following puzzle. “I am three years younger than my brother, and I am 2 years older than my sister. My mom's age is one less than three times my brother's age. When you add all our ages, you get 87. What are our ages?”

Jada writes this equation for the sum of the ages:

(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87

Match the meaning to each term of the equation.

x

x + 3

(x - 2)

3(x + 3) - 1

87

Answers

Answer:

x = 13

Andre is 13, Andre's brother is 16, Andre's sister is 11, Andre's mom is 47

Answer:

x = 13

Andre is 13

Brother is 16

Sister is 11

Mom is 47

All together they are 87!

Step-by-step explanation:

x + x + 3 + x - 2 + 3x + 9 - 1 = 87

6x + 9 = 87

6x = 87 - 9

6x = 78

x = 78/6

Which of the following expressions is modeled on the number line?
2 ⋅3
-2(3)
6 ÷ -3
0+6

Answers

Answer:

The given line number suggests that there are 2 sets of 3 units.

Hence,

2 x 3 = 6 should be right answer.

Therefore, option (A) is true.

Step-by-step explanation:

We can easily determine that on the line number:

There are 3 units from 0 to 3.Then there are another 3 units from 3 to 6.

In other words, there are 2 sets of 3 units.

Hence,

2 x 3 = 6 should be right answer.

Therefore, option (A) is true.

Answer A: 2*3

Answer is A. First one
2 * 3 = 6
On the number line, 0 to 3, it's 3 units
then 3 to 6, there's another 3 units
so 2 x 3(units) = 6
