Answer:

r ≥ -1. it is A because r is greater than or equal to -1.

I am sorry <u>if</u> I got it wrong.

Step-by-step explanation:

3r+2(12r+7) ≤ 5r-8

27r+14 ≤ 5r-8

I subtract 27r and 5r.

22r+14 ≤ -8

I subtract 14 and -8.

22r ≤ -22

Divide 22 on both side.

r ≥ -1

The larger of two numbers is eight more than twice the smaller. The sum of the numbers is 10 less than three times the larger. F
Alinara [238K]

Answer:

-2 and 4

Step-by-step explanation:

Let's set the larger number to x, and the smaller to y. With these, we can set up our equations.

x = 2y + 8

x + y = 3x - 10

Now, we put the value of x into the second equation.

2y + 8 + y = 3(2y + 8) - 10

Now we can solve for y

3y + 8 = 6y + 24 - 10

3y + 8 = 6y + 14

8 = 3y + 14

-6 = 3y

-2 = y

Now that we have the smaller number, we can put it into the first equation and solve for the larger.

x = 2*-2 + 8

x = -4 + 8

x = 4

So your two numbers are -2 and 4.

Serhud [2]
In the problem it is already given that Weston Laundry washed 285.38 pounds of towel and 353.47 pounds of sheets from local hotels in 1 day. Firstly we have to find the total pounds of linens that Weston Laundry has washed in 7 days. Then only will it be possible to find the amount of linen washed in a day.
Then t
Total linen washed by Weston Laundry in 7 days = (285.38 + 353.47) pounds
                                                                               = 638.85 pounds.
Then
The amount of linen washed by Weston Laundry in 1 day = 638.85/7
                                                                                             = 91.26 pounds
So Weston Laundry washed about 91.26 pounds of linen each day.
