Carla passes fertilizer on Amistad's yard. She covers 150 square feet every 3 hours. How many square feet per hour does Carla cover? Explain your reasoning.

Answers

Answer 1

Answer:

50 square feet

Step-by-step explanation:

150/3= 50

Answer 2

Answer:

the answer is 50

Step-by-step explanation:

if she does 150 square feet every 3 hour

you need the 3 hours down to 1 so in order to do that

you need to divide 3 by 3

what you do to one side must be done to the other

150 by 3

so it will look like

3/3 = 150/3

1 = 50

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

Answer:

Andre is 13

Brother is 16

6x = 87 - 9

6x = 78

x = 78/6

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.
