Answer:

The answer is 2(x+3)=3 * 2(x-1)-2x

Step-by-step explanation:

full question:

Kim works 3 hours more each day than Jill does, and Jack works 1 hour less each day than Jill does. Over 2 days, the number of hours Kim works is equal to the difference of 3 times the number of hours Jack works and the number of hours Jill works. How many hours does each person work each day? Let x be the number of hours Jill works in one day.

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

2(x+3)=6(x-1)-2x

2x+6=4x-6

2x+6-6=4x-6-6

2x=4x-12

-2x=-12

-2x/-2=-12/-2

x=6

If m and n can be any integers such that n<4 and 4m - 3n < 20, which of following is the solution set for m?A m <7.25B

soldier1979 [14.2K]

If we multiply the inequality n<4 by 3 we get the following:

$(n$

Now, on the next inequality we have the following:

$\begin{gathered} 4m-3n$

By transitive property, we have:

$\begin{gathered} 3n$

therefore, the solution set for m is m<8

5 more than 3 times a variable, x, is 23

Monica [59]

3x + 5 = 23

5 more than(addition) 3 times(multiplication) a variable(x) is(equals) 23

(you add 5 to 3x)

If you need to solve for "x", you need to isolate/get the variable "x" by itself in the equation:

3x + 5 = 23 Subtract 5 on both sides

3x + 5 - 5 = 23 - 5

3x = 18 Divide 3 on both sides to get "x" by itself

$\frac{3x}{3} =\frac{18}{3}$

x = 6

Radda [10]

Answer:

4 ounces of corn and 4 ounces of squash

Step-by-step explanation:

Let S be the no. of ounces of squash

Let C be the no. of ounces of corn

C》2 --> (A)

S》C --> (B)

Total protein 》 3

½C + ¼S》3 --> (C)

Solve A and C simultaneously

½(2) + ¼S = 3

¼S = 2

S = 8

C = 2, S = 8

Solve B and C simultaneously

½S + ¼S = 3

¾S = 3

S = 4

C = 4, S = 4

Three possible extreme combinations

C = 2, S = 8: Total = 10

C = 4, S = 4: Total = 8

Minimum is 8 ounces

Is (4,-5), (0,-5), (11,30), (17,10) a function

Ratling [72]

Answer:

Yes, it is a function

Step-by-step explanation:

A function is a set of ordered pairs where there is no two of the same domain. The domain is the first coordinate which is x. In this case, the x coordinates are 4, 0, 11, 17. There is no two of the same domain so this is a function.

Hope This Helps :)
