Answer:

I will just try

Step-by-step explanation:

3(2x+1)=12+3x

6x+3=12+3x

6x-3x=12-3

3x=6

x=6÷3

x=2

now,

3(2x+1)=12+3x

3(2×2+1)=12(3×2)

3×5=12×6

15=72

The owners of a recreation area are filling a small pond with water. Let WB the total amount of water in the pond(in liters). Le
alexira [117]

Answer:

As we can see the domain is the: "number of minutes water has been added". And from the information given the values for T are between 0 and 60 so then the set of values would be "the set of all real numbers from 0 to 60", and we start from 0 because the time can't be negative.

For the range who represent "amount of water in the pond (in liters)" we need to analyze the possible values for W, since T is defined between 0 and 60 the limits for W are:

W(0)=35*0+300=300

W(60)=35*60+300=2400

So then the set of values for the range are "the set of all real numbers from 300 to 2400" liters.

Step-by-step explanation:

Assuming this complete problem: "The owners of a recreation area are filling a small pond with water. Let W be the total amount of water in the pond (in liters). Let T be the total number of minutes that water has been added. Suppose that  gives as a W function of during the next 60 minutes.

Identify the correct description of the values in both the domain and range of the function. Then, for each, choose the most appropriate set of values. "

Solution to the problem

As we can see the domain is the: "number of minutes water has been added". And from the information given the values for T are between 0 and 60 so then the set of values would be "the set of all real numbers from 0 to 60", and we start from 0 because the time can't be negative.

For the range who represent "amount of water in the pond (in liters)" we need to analyze the possible values for W, since T is defined between 0 and 60 the limits for W are:

W(0)=35*0+300=300

W(60)=35*60+300=2400

So then the set of values for the range are "the set of all real numbers from 300 to 2400" liters.

Can someone help me ?! Relationships between angle measures and side lengths in a triangle.
Likurg_2 [28]

Answer:

41<67<72

Step-by-step explanation:

Since all 3 angles in a triangle add up to 180 degrees, you will need to add the two angles you have, and then subtract that from 180 to find the measurement of angle K.

41+67=108

180-108=72

Now you would just use your common knowledge and put arrange the measurements to be least to greatest!

41<67<72
