Sarah has to pay a one-time $300 deposit for her apartment. Each month she pays $700 for rent. How much would Sarah pay for “n” months?
Answer:
700n + 300
Step-by-step explanation:
We know that no matter what happens, Sarah has to pay a One-Time $300 for her deposit.
Now, we know that for every month she stays in the apartment, it will cost her $700.
So, we can come up with a formula to find out how much she would pay:
700n + 300

lets start by putting our numbers into fractions then finding a like value. 35 in this case. 1/7 equals 5/35 and 1/5 equals 7/35 now we add these together and get 13/35. our next step is to flip this to 35/13 and take put any whole numbers. in this case 2 whole numbers can be made
leaving
9/13

An ice cream shop charges customers a set amount for one scoop of ice cream, plus a charge per topping. If two toppings would cost a total of $3.99, and 4 toppings $4.99, what is the rate per topping?
Answer:
$0.50 per topping
Step-by-step explanation:
x + 2t = 3.99
x + 4t = 4.99
x + 2t = 3.99
2t = 3.99 - x
t = 1.995 - 0.5x
x + 4t = 4.99
x + 4(1.995 - 0.5x) = 4.99
x + 7.98 - 2x = 4.99
7.98 - x = 4.99
-x = -2.99
x = 2.99
t = 1.995 - 0.5(2.99)
t = 1.995 - 1.495
t = 0.50
The rate per toppings is given by the equation A = $ 0.50
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of the toppings be represented as A
Now , the equation will be
The cost of 2 toppings = $ 3.99
So , 2A = 3.99 be equation (1)
The cost of 4 toppings = $ 4.99
And , 4A = 4.99 be equation (2)
Subtracting equation (1) from equation (2) , we get
4A - 2A = 4.99 - 3.99
On simplifying the equation , we get
2A = 1.00
Divide by 2 on both sides of the equation , we get
A = $ 0.50
Therefore , the value of A is $ 0.50
Hence , the cost of one toppings is $ 0.50

Answer:
x = 133 x = -7
Step-by-step explanation:
| x/7 - 9| = 10
There are two solutions, one positive and one negative
x/7 - 9 = 10 x/7 - 9 = -10
Add to to each side
x/7 - 9+9 = 10+9 x/7 - 9+9 = -10+9
x/7 = 19 x/7 = -1
Multiply each side by 7
x/7 *7 = 19 *7 x/7*7 = -1*7
x = 133 x = -7

Given f(x)=2x+1, find the range value if the domain value is 1.75. *
Answer:
4.5
Step-by-step explanation:
Domain means that value of x and range means the value of f(x) so
[tex]f(x)=2x+1 \\f(1.75)=2(1.75)+1\\f(1.75)=4.5[/tex]
so the range value is 4.5
Regina’s teacher recently gave her a homework assignment on solving equations. Since she has been thinking about saving for a new cell phone, she decided to use the assignment as an opportunity to model a savings plan.
She created this equation to model the situation. In it, y represents the total amount saved for the new cell phone, 74 is the amount of money she has now, 40 is the amount of money she saves each month for the phone, and x represents the number of months since she started saving a regular amount:
74 + 40x = y.
She then solved the equation to determine how many months she’d need to save to have enough to purchase the new cell phone. Review her work, and select the error.
Answer:
The answer is 4.
Step-by-step explanation:
In her solution, there is an error in step 4. She used the multiplication property of equality but its a division property.
Given that,
A solution is given, we have to review the solution and mark the steps that contain an error.
In mathematics, it deals with numbers of operations according to the statements.
Here,
In the solution, every step is accurate and correct, except for step 4. she divided the equality by 40 and she wrote the step as multiplication property of equality which is wrong the correct statement for step 4 is the division property of equality.
Thus, in her solution, there is an error in step 4. She used the multiplication property of equality but its a division property.

Step-by-step explanation:
Lets arrange the numbers first
23, 27, 32, 32, 36, 38, 46, 49, 51, 55, 58, 59, 63
so find how many numbers there are
- 13
the middle number of 13 is 7
so the 7th number should be the median of this sum
7th number - 46
Answer - 46
Hope you understand
:-)
The data given results in this list
{23,27, 32,32,36,36, 46,49, 51,55,58,59, 63}
The middle most value is 46 since there are 6 items below it {23,27,32,32,36,36} and 6 items above it {49,51,55,58,59,63}.
It might help to cross off the outer values and work your way in so you can spot the middle value easier.
