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?
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.

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
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.

A factory makes candy bars and ships them in cases.
• Each case contains 6 boxes of candy bars.
• Each case contains a total of 144 candy bars.
• Each box contains the same number of candy bars.
What is the number of candy bars per box?
Answer:
24 candy bars
Step-by-step explanation:
1case=6boxes of candy bars
1 case=144 candy bars
1 box has the same number of candy bars as the rest
What is the number of candy bars in 1 box
6 boxes = 144 candy bars
1 box = ?
144×1 ÷6= 24 candy bars
1 box has 24 candy bars

Step-by-step explanation:
what is the slope of the line Y equals 3
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.
Best of Luck!
Xavier climbs 9 feet up into an apple tree. What integer represents the direction and how far he will climb to get back down to the ground? What does the integer 0 represent in this situation? The integer represents Xavier’s climb down. The integer 0 represents .
Answer:
The answer is "-9 feet and Ground-level".
Step-by-step explanation:
Given value:
total length or distance from apple tree = 9 feets
In the calculation of the distance between both the ground and the tree will be the same.
If he gets higher 9 feet, he will go back to the ground 9 feet, in this case, the represents ground value is equal to 0.
In the calculation of absolute values it value is opposite but the same.

Point L is on line segment KM. Given LM = 3x + 3, KM = 5x + 4, and
KL = 5x + 1, determine the numerical length of KM.
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
[tex]x = 0[/tex]
Substitute 0 for x in [tex]KM = 5x + 4[/tex]
[tex]KM = 5 *0 + 4[/tex]
[tex]KM = 0 + 4[/tex]
[tex]KM = 4[/tex]

Evaluate f(4) =6(4)+5
X=4
Need answers ASAP
Sounds like you want to find f(4) when f(x) = 6x+5
If so, then
f(x) = 6x+5
f(4) = 6(4)+5 ... replace x with 4
f(4) = 24+5
f(4) = 29

Answer:
4. 770 people
5. 16 min
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
8 x
just cross multiply:
15x = 30(8)
x = 240 / 15
x = 16 mins
6. 18 laps = x
10 6
just cross multiply:
10x = 18(6)
x = 108 / 10
x = 10.8 laps
explain why 2a+3b=5ab
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
The key is that the variable portions must match up to be able to add them.

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

3[-x + (2 x + 1)] = X – 1
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
