Answer:

Step-by-step explanation: Alright adding fractions here we go.

3 3/5 + 2 1/4

First add up the whole numbers. 3+2=5

A lawn company advertises that they can spread 7,500 square feet of grass seed in 2 1/2
den301095 [7]
If you would like to know the number of square feet of grass seeds that the lawn company can spread per hour, you can calculate this using the following steps:

7500 square feet ... 2 1/2 hours = 5/2 hours
x square feet = ? ... 1 hour

7500 * 1 = 5/2 * x
7500 = 5/2 * x       /*2/5
x = 7500 * 2 / 5
x = 3000 square feet

The correct result would be 3000 square feet.

The set of possible values of m is (5, 7, 9).
k0ka [10]

Plug in each possible value into the equation.

when m = 5

2k = m + 3

2k = (5) + 3

Simplify

2k = 8

isolate the k, divide 2 from both sides

2k/2 = 8/2

k = 8/2

k = 4

When m = 5, k = 4

-------------------------------------------------------------------------------------------------------------------

2k = m + 3

when m = 7

2k = (7) + 3

2k = 10

2k/2 = 10/2

k = 10/2

k = 5

when m = 7, k = 5

------------------------------------------------------------------------------------------------------------------

2k = m + 3

When m = 9

2k = (9) + 3

2k = 12

2k/2 = 12/2

k = 12/2

k = 6

when m = 9, k = 6

-------------------------------------------------------------------------------------------------------------------

hope this helps
