Answer:

5 - 3c + 21 --> 3 terms

Step-by-step explanation:

Step 1: A term is a number by it self or a number & variable. Ex: 5 + 6c.<u> </u><u><em>5</em></u> would be one term, <u><em>6c</em></u> would be the other.

Step 2: Now, let's look at 5 - 3c + 21.

Step 3: 5 is a term by it self. Since there is no variable, it's just 5.

            -3c is a term by itself. And, there is a variable, so it's -3c.

            +21 is a term by itself. Since there is no variable, it's just +21.

Note: You must carry the sign with it. For Ex: 5 - 3x + 21

         If you were given a question, "What is the third term of this equation?" you would write, "+21". You will always need to carry the sign with the number.

What is the slope of the line that passes through these two points?
Dmitry_Shevchenko [17]

Answer:

undefined

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

   = ( 9-3) / ( 2-2)

   = 6/0

When we divide by zero, the result is undefined

This means the slope is undefined

2t + 1 + 6 + 4t = 55<br> show your work
Ivan
Combine like terms, 1+6 is 7 and 2t+4t is 6t. so 6t+7=55. get the t by itself by subtracting 7 from both sides. 6t=48, divide by 6. t=8

A tal company has chairs and tables for rent. The total cost to rent 3 chairs and 2 tables is $22. The total cost to rent 5 chai
den301095 [7]

Answer:

$1.5 and $8.75

Step-by-step explanation:

Given data

let tables be x and chairs be y

The total cost to rent 3 chairs and 2 tables is $22

so

3x+2y=22----------1

The total cost to rent 5 chairs and 6 tables is $60

so

5x+6y=60---------2

the system of equation is

3x+2y=22----------1X 6

5x+6y=60---------2X 2

 18x+12y= 132

- 10x+12y=120

8x+0y= 12

8x= 12

divide both sides by 8

x= 12/8

x=$1.5

put x= 1.5 in 2

5(1.5)+6y=60---------2

7.5+6y=60

6y=60-7.5

6y=52.5

divide both sides by 6

y= 52.5/6

y=$8.75
