If you bought a $3 smoothie and your total (with tip) is $3.60, you have to divide 3.6/3. You get 1.2, which means you left a 20% tip, which would be .2 in decimal form.
To find the percent tip, divide the tip amount by the total cost and multiply by 100.
Explanation:To find the percent tip, we need to first calculate the total cost of the smoothies and the tip. Since the smoothies cost $3 each, the total cost of the smoothies is $3 * 2 = $6. Let's assume the tip amount is x dollars. The split total (including the tip) is $3.60, which is equal to half of the total cost plus the tip: $3 + $3 + x = $6 + x. Solving this equation, we can find the value of x:
$6 + x = $3.60 * 2$6 + x = $7.20x = $7.20 - $6 = $1.20The tip amount is $1.20. To find the percent tip in decimal form, we divide the tip amount by the total cost and multiply by 100: $1.20 / $6 * 100 = 20%. Therefore, you and your friend left a 20% tip.

solve y=x^2+23 for x
For this case we must clear x from the given equation:
[tex]y = x ^ 2 + 23[/tex]
We passed 23 subtracting the other side of equality:
[tex]y-23 = x ^ 2[/tex]
By definition, [tex]a ^ 2 = b[/tex]is written as [tex]a = +/-\sqrt{b}[/tex]
So, we have:
[tex]x = + / -\sqrt{(y-23)[/tex]
So, the solution of [tex]y = x ^ 2 + 23[/tex] for x is:
[tex]x = + / -\sqrt{(y-23)[/tex]
Answer:
[tex]x = + / -\sqrt{(y-23)[/tex]

solve the equation x/4+5/8=3/8
X/4 +5/8 = 3/8
X/4 = 3/8-5/8
X/4 = (3-5)/8
X/4 = -2/8
Multiply both sides by 4 we get
4x/4 = -8/8
X = -1

Multi-step: This week, Maddie worked 2 1/2 hours on Monday, 2 2/3 hours on Tuesday, and 3 1/4 hours on Wednesday. How many more hours will Madie need to work this week to make her goal of 10 1/2 hours a week? ( show steps please)
Answer:
2 1/12
Step-by-step explanation:
Maddie wants her total hours to be 10 1/2. That is, she want the sum of the daily hours to be that value:
... 10 1/2 = 2 1/2 + 2 2/3 + 3 1/4 + (more hours)
Subtracting the contant terms on the right, we can find the value of (more hours).
... 10 1/2 - 2 1/2 - 2 2/3 - 3 1/4 = (more hours)
Doing the subtraction left to right, we have
... 8 - 2 2/3 - 3 1/4 = (more hours)
... 5 1/3 - 3 1/4 = (more hours)
... 2 1/12 = (more hours)
The only subtraction that may require any extra effort is subtracting 1/4 from 1/3.
... (1/3) - (1/4) = (4/12) - (3/12) = (4 -3)/12 = 1/12

Problem
You deposit $2000 into a bank account paying 4.5% simple interest per year. You left the money in for 8 years. How much interest do you get at the end of those 8 years?
Result
The interest is $720.
Then you add the money you invested to your interest so your answer would be ' C ',
I think I'm not that great with math but I really hope I helped you .
Answer:
D. $2630
Step-by-step explanation:
Given,
The principal amount, P = $ 2000,
Annual rate of interest, r = 4.5 % ,
Thus, the interest for 7 years,
[tex]I=\frac{P\times r\times 7}{100}[/tex]
[tex]=\frac{2000\times 4.5\times 7}{100}[/tex]
[tex]=\frac{63000}{100}[/tex]
[tex]=630[/tex]
Hence, the amount after 7 years or at the beginning of the 8th year is,
[tex]A=P+I=2000+630=\$ 2630[/tex]
Option 'D' is correct.

Solve for x. −5x−4(x−6)=−3 Enter your answer in the box. x =
-5x -4(x-6) = -3
distribute
-5x -4x+24 = -3
combine like terms
-9x +24 = -3
subtract 24 from each side
-9x = -27
divide by -9
x = 3
Answer:
x=3
Step-by-step explanation:
−5x−4(x−6)=−3
To solve for x:
for this we have to make the equation in such a way that the variable x lies on the left side and constant terms on the right side.
First distribute -4 over x and -6
We get -4x+24.
Substitute in the equation.
-5x-4x+24 =-3
Subtract 24 from both the sides
-5x-4x = -3-24
Or =9x = -27
Divide by -9

An ice hockey rink is a rectangle with a perimeter of 174 meters. The length is 9 meters more than twice the width. Find the length and width.
let L be the length
let W be the width
L = 9 + 2W
since the perimeter = 2L + 2W
Perimeter = 2 x (9 + 2W) + 2W
174 m = 18 + 4W + 2W
174 m = 18 + 6W
6W = 174 - 18
6W = 156
W = 156/6
W = 26
L = 9 + 2W
L = 9 + 2 x 26
L = 9 + 52
L = 61
Therefore, length = 61 m and width = 26 m.

Which of the following statements is correct?
• 15 > 700
• 15 = 700
• 15 < 700
• 700 = 700
The last two ones
< Less than
> Greater than
= Equal to
The correct statements are '15 < 700' and '700 = 700'.
In mathematics, we use comparison operators to establish relationships between numbers.
By comparing the given numbers, we see that 15 is less than 700, which makes the correct statement: '15 < 700'. Additionally, the statement '700 = 700' is also correct, as these values are identical and other statements are incorrect.

if m<mkl=83. m<jkl=127. and m<jkm=(9x-10). find the value of x
Final answer:
To find the value of x, we can use the given equations and the Angle Sum Property of a Triangle. By substituting the known values into the equation (9x-10), we can solve for x.
Explanation:
To find the value of x, we can use the facts given in the question. We know that m<mkl = 83 and m<jkl = 127. We also know that m<jkm = (9x-10). From these facts, we can form two equations:
1. m<mkl = 83
2. m<jkl = 127
Using these equations, we can determine the value of x.
Let's solve the first equation:
1. m<mkl = 83
Since m<mkl = 83 and m<jkl = 127, we can substitute these values into equation (9x-10) according to the Angle Sum Property of a Triangle:
2. 83 + 127 + (9x-10) = 180
Simplifying the equation, we get:
3. 210 + 9x - 10 = 180
Combining like terms, we have:
4. 9x + 200 = 180
Subtracting 200 from both sides, we get:
5. 9x = -20
Dividing both sides by 9, we find:
6. x = -20/9
Therefore, the value of x is -20/9.

The cost (in dollars) of making N birthday cakes is represented by C= 24n + 35. How many birthday cakes are made when the cost is $395? Show your work and include units in your Answer.
The cost is $395. You are trying to find n in 24n + 35.
Set C = 395.
You get 395 = 24n + 35.
Solve for n by first subtracting 35 from both sides of the equation:
395 - 35 = 360.
24n + 35 - 35 = 24n.
Now you have 360 = 24n. Divide both sides by 24 to get:
15 = n.
So, 15 birthday cakes are made when the cost is $395.
The Number of cakes that can be made with $395 is 15.
The cost function :
C(n) = 24n + 35
The number of cakes, n that can be made with $395:
Substitute, C(n) = 395 into the equation :
395 = 24n + 35
24n = 395 - 35
24n = 360
Divide both sides by 24
n = 360 / 24
n = 15
Therefore, 15 cakes can be made with $395

Your answer would be 4379 members because at the very beginning you had started off with 4372 members, however as the months go by changes happen. On october, it changed by -10, meaning that 10 students left the school meaning 4372-10=4362 members remaining. Then there's november with -8, so you subtract 8 from your new total 4362-8=4354. Then december comes, and this time it's a positive number, so you have to add 23 to 4354, giving you a new total of 4377. Then there's january, and its back to a negative number so you subtract 12 from 4377, 4377-12=4365. Then february comes and it's a change of a positive number, so you add 3 to the 4365, giving you 4368. And then finally by march, it's another positive number so you add 11 to your total, giving you 4379 students which are now at school. So basically if it's a negative change, subtract from the total, and if it is a positive, add to it. And you have to continue with the total that you got from the previous change that you did. Hope this was helpful
basically you start with 4372 the table shows what happens during the school so after September you go to October which is -10 so you end up with 4362 then, November which is -8 so you get 4354 then in December you have +23 which makes 4377 then in January you have -12 which makes 4365 then in Feburary you have +3 which makes 4368 then in march you have +11 so 4379 so
