Answers

y = 3 is written in slope-intercept form (y = mx + b).

The only variable we are given in this equation is "b" which is "3".

We don't have a slope variable at all which means the slope is 0 or undefined.

The y-intercept is 3.

kaitlin bought some books. she spent a total of 45 after a discount of $6 off her total purchase. Each book cost $3. How many books did she buy

Answers

Answer:

17

Step-by-step explanation:

Answer: She bought 17 books

Step-by-step explanation:

Add $6 to the amount that she paid to find out how much money she would have paid.

45 + 6 = 51  so she would have paid $51  

Now divide 51 by 3 to find out how many books she bought.

51 / 3 = 17  

So because of the discount, she paid $45 for 17 books.

3[-x + (2 x + 1)] = X – 1

Answers

Your question has been heard loud and clear.

3[-x + (2 x + 1)] = X – 1

= 3[-x+2x+1]= x-1

= 3 [ x+1] = x-1

= 3x+ 3 = x-1

3x-x = -3-1

2x= -4

so , x = -4/2 = -2

Therefore , x = -2

6.  10.8 laps

Step-by-step explanation:

4.  330 people   =       x        

      3 hours               7 hours

just cross multiply:

3x = 330(7)

x = 2310 / 3

x = 770 people

5.   15 laps =   30 laps

x = 240 / 15

x = 16 mins

6.   18 laps =       x      

        10              6

just cross multiply:

John has a debit card with $100.00 on it. He uses his debit card to buy his lunch everyday. His lunch costs $4.50 per day. How many lunches can John buy?

Answers

Answer:

He can buy 22 lunches.

Step-by-step explanation:

To find how many he can buy if he had $100, we must divide the cost of one lunch to the amount of money he has.

(Round to the nearest whole number to get the exact amount of lunches that he can buy.)

1 lunch = $4.50

So:

=$100 ÷ $4.50 = 22.222....

=22.222.... = 22

Hope this helps! I'm sorry if it's wrong.

Owen creates this model to determine the product of two decimals. Which
equation shows Owen's model?

Answers

Answer:

3.7×1.2=3+0.7+0.6+0.14=4.44

Step-by-step explanation:

I added all the choices together I picked the one that had the same answer. Good luck!

Owen's model is represented by -

3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that Owen creates this model to determine the product of two decimals.

The equation that represents the Owen's model is -

3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

Therefore, Owen's model is represented by -

3.2 x 1.7 = 3 + 2.1 + 0.2 + 0.14 = 5.44

explain why 2a+3b=5ab

Answers

That's not correct. The terms 2a and 3b are not like terms, so we cannot combine them to get 5ab. We simply leave it as 2a+3b.

If you had 2a+3a, then it would simplify to 5a

Similarly, 2b+3b = 5b

Or you could have 2ab+3ab = 5ab

Point L is on line segment KM. Given LM = 3x + 3, KM = 5x + 4, and
KL = 5x + 1, determine the numerical length of KM.

Answers

Answer:

[tex]KM = 4[/tex]

Step-by-step explanation:

Given

[tex]LM = 3x + 3[/tex]

[tex]KM = 5x + 4[/tex]

[tex]KL = 5x + 1[/tex]

Required

Determine KM

The relationship between the given parameters is:

[tex]KM = KL + LM[/tex]

Substitute the values of KM, KL and LM

[tex]5x + 4 = 5x + 1 + 3x + 3[/tex]

Collect Like Terms

[tex]5x - 5x - 3x = 1 + 3 - 4[/tex]

[tex]-3x = 0[/tex]

Divide through by -3

Substitute 0 for x in [tex]KM = 5x + 4[/tex]

[tex]KM = 5 *0 + 4[/tex]

[tex]KM = 0 + 4[/tex]
