Answer:
Step 1: Write down the percent divided by 100 like this: 1200% = 1200 / 100. Step 2: Multiply both top and bottom by 10 for every number after the decimal point: As 1200 is an integer, we don't have numbers after the decimal point. So, we just go to step 3.

Estimate, and then find the quotient. Use your estimate to check for reasonableness. 9,157÷32
Answer:
9,157 divided by 32=286.15625
9,157 rounded is 9.000
32 rounded is 30
9,000 divided by 30 equals the quotient of 300

A store has jeans on sale for 30% off. If the jeans
originally cost $40, how much will you spend on the jeans
after the discount and sales tax (8%)?
Answer:
$30.24!Step-by-step explanation:
Find the discounted price by setting up an equation
40-.3(40) AKA 30% of the original price is being taken off of the original price
Evaluate
40-12
$28 = discounted price
Sales tax is based on the reduced/discounted price* remember this

Answer:
x=2 (work is correct)x=4x=44x=4x=any numberimpossible; no such numberStep-by-step explanation:
1. The equation is ...
3x +5 = 11
3x = 11 -5 = 6
x = 6/3 = 2 . . . . matches the work shown
__
2. The equation is ...
(x +2)·5 = 30
x +2 = 30/5 = 6
x = 6 -2 = 4
__
3. The equation is ...
(x/2) +2 = 24 . . . . matches the work shown
x/2 = 24 -2 = 22
x = 22·2 = 44
__
4. The equation is ...
2x +8 = x +12
2x = x + 12 -8 = x +4
2x -x = x -x +4
x = 4
__
5. The equation is ...
2x +4 -x -3 = x +1
x +1 = x +1 . . . . . true for any value of x
__
6. The equation is ...
(3x +6) -2x = x +3
x +6 = x +3 . . . . . not true for any number
_____
Additional comment
The work shown is correct. You find x by writing and solving an appropriate equation. To solve the equation, undo the steps that are done to x. Undo addition by adding the opposite. Undo multiplication by diving by the multiplier. It often helps to collect terms before you start the "undo" steps.
For x on both sides of the equation (as in problems 4–6), you can subtract the term with the lowest coefficient. (Of course, you must subtract it from both sides of the equation.) In problem 5, if you do that, you get 1=1, which is true for any value of x. In problem 6, if you do that, you get 6=3, a false equation, indicating no value of x will make it true.
The Answer is:
1. x=2
2. x=4
3. x=44
4. x=4
5. x=any number
6. no such number

URGENT!!! PLEASE HELP!! two cars leave at the same time from two cities that are 374 miles apart and travel towards each other. Car 1 travels 50 mph and Car 2 travels 60mph. How long do they travel before they meet?
Answer:
3 hours and 40 minutes I think
Step-by-step explanation:
Answer:
3 hours and 40 mins
Step-by-step explanation
First, you check 3 hours times 50 miles and 3 hours times 60 miles to get how close they are. 3x50=150, and 3x60=180. 150+180=330. Then you multiply 4/6 or 2/3 by 5 and 6 then add them (because 40 mins is 2/3 of an hour) 50x2/3/2=100/3 and 60x2/3=120/3=40. 40+50/3=73 1/3. 73 1/3+330= 3 hours and 40 mins.
Gabby needed to type up 12 documents during the week. By Wednesday, she only finished 3 1/5 documents. On Thursday, she finished another 5 3/4 documents. If she finished writing all documents by Friday, how much did she write on Friday?
Answer: She wrote [tex]3\dfrac{1}{20}[/tex] documents on Friday.
Step-by-step explanation:
GIven: Total documents needed to be done = 12
If she finished writing all documents by Friday, then the number of documents written on Friday = 12-(work done by Wednesday) - (work done on Thursday)
[tex]= 12 -(3\dfrac15)-(5\dfrac34)\\\\=12-\dfrac{16}{5}-\dfrac{23}{4}\\\\=\dfrac{12\times20-16\times4-23\times5}{20}\\\\=\dfrac{240-64-115}{20}\\\\=\dfrac{61}{20}\\\\=3\dfrac{1}{20}[/tex]
Hence, She wrote [tex]3\dfrac{1}{20}[/tex] documents on Friday.
A system of equations has no solution. If y = 8x + 7 is one of the equations, which could be the other equation?
2y = 16x +14
y = 8x – 7
y = –8x + 7
2y = −16x − 14
Step-by-step explanation:
the answer is 2y=16x+14
The equations that could be the other equation are y = 8x - 7 and y = -8x + 7.
If the system of equations has no solution, then the other equation must not have the same slope-intercept form as the first equation.
The slope-intercept form of the equation y = 8x + 7 is y = mx + b, where m is the slope and b is the y-intercept. Thus, the slope of the first equation is 8 and the y-intercept is 7.
Now let's check each of the given equations to see which one could be the other equation.
2y = 16x + 14
Rewriting this equation in slope-intercept form, we get y = 8x + 7, which is the same as the first equation. Therefore, this equation cannot be the other equation.
y = 8x – 7
This equation has the same slope as the first equation but a different y-intercept. Therefore, it represents a different line and could be the other equation.
y = –8x + 7
This equation has a slope that is the negative of the slope of the first equation, so it represents a different line. Therefore, it could be the other equation.
2y = −16x − 14
Rewriting this equation in slope-intercept form, we get y = -8x - 7, which has the same slope as the first equation but a different y-intercept. Therefore, it represents a different line and could be the other equation.

1/2
-2

Answer:
Option B : 1/2 is the correct answer.
Step-by-step explanation:
Given ordered pairs are;
(3, 6) and (5, 7).
We have to find the rate of change which is also known as slope.
Slope is the steepness of a line.
The formula of slope is given by;
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m = [tex]\frac{7-6}{5-3}[/tex]
m = [tex]\frac{1}{2}[/tex]
