Let h bet the # of hours worked
If Cynthia earns $13 per hour then her equation would be:
C = $13h
If Amy makes $1.5 more per hour then her equation would be:
A = $14.5x
Now lets plug in some numbers:)
A = $14.5(43.5)
A = $630.75

Hi, I still have to struggle with this and it's due later today! If someone could show me how to do it I will make you're a brain list and give you 28 points I need help w part C to E. I would appreciate it.
Answer:
C) Explain how the equations are equal and just prove it with a check or just plug in a number like for ex: x=1 and I checked with both and it equals out.
d) Use inverse operations (or you can say do the order of operations in reverse and then use invers operations), provide an example if you think what you said doesn’t make sense, like for
Ex: 2x-1=43+5x
2x=44+5x (add the -1)
-3x=44 (subtract 5x to both sides)
X=44/-3 (isolate the variable by dividing 3 on both sides)
An example is always better
E) Just use inverse operations and solve it like what you would normally do

So, anything in the first quadrant would be positive (for both values of x and y).
That means E and F are the correct choices, since both (4, 8) and (2, 2) are positive and would be found in the first quadrant.

Find the 93rd term of the arithmetic sequence -5, -15, -25, ...−5,−15,−25,...
Answer:
The nth term will be:
[tex]a_{93}=-925[/tex]Step-by-step explanation:
Given the sequence
-5, -15, -25, ...
An arithmetic sequence has a constant difference 'd' and is defined by
[tex]a_n=a_1+\left(n-1\right)d[/tex]
computing the differences of all the adjacent terms
[tex]-15-\left(-5\right)=-10,\:\quad \:-25-\left(-15\right)=-10[/tex]
The difference between all the adjacent terms is the same and equal to
[tex]d=-10[/tex]
The first element of the sequence is:
[tex]a_1=-5[/tex]
Thus, the nth term will be:
[tex]a_n=a_1+\left(n-1\right)d[/tex]
substituting the values [tex]d=-10[/tex]; [tex]a_1=-5[/tex]
[tex]a_n=-10\left(n-1\right)-5[/tex]
[tex]a_n=-10n+5[/tex]
Plug in n = 93 to determine the nth term
[tex]a_{93}=-10\left(93\right)+5[/tex]
[tex]a_{93}=-930+5[/tex]
[tex]a_{93}=-925[/tex]
Therefore, the nth term will be:
[tex]a_{93}=-925[/tex]pls help i got stuck

Step-by-step explanation:
Here are the ingredients needed to make 8 biscuits.
Biscuits
To make 8 biscuits
90g of butter
35g of sugar
125g of flour
Hamid has 315g of butter
150g of sugar
500 g of flour
Work out the greatest number of biscuits Hamid can make.
The greatest number of biscuits Hamid can make is 28.
What is the greatest number of biscuits Hamid can make?The first step is to determine the quantity of each ingredient needed to make 1 biscuits.
Grams of butter needed to make 1 biscuit : 90 / 8 = 11.25gGrams of sugar needed to make 1 biscuit : 35 / 8 = 4.38gGrams of flour needed to make 1 biscuit : 125 / 8 = 15.63gNow determine the number of biscuits that can be made using each of the ingredients
Butter = 315 / 11.25 = 28Sugar = 150 / 4.38 = 34Flour = 500 / 15.63 = 32To learn more about ratios, please check: https://brainly.com/question/19257327

A surfboard was originally priced at $199. The store reduced the price by 10%. A customer bought the surfboard using a coupon for $20 off. How many dollars did the customer pay?
Answer:
$159.1
Step-by-step explanation:
Given that:
Original price of surfboard = $199
Reduction of price done = 10%
Then a coupon is used by a customer for $20 off.
To find:
How many dollars were paid by the customer?
Solution:
First of all, let us find the price after the reduction of 10% from the original price.
10% of $199 = [tex]\frac{10}{100}\times 199 = \$19.9[/tex]
This price is reduced from the original price.
Price after reduction = $199 - $19.9 = $179.1
Now, again there is coupon of $20.
Therefore, final price that the customer had to pay = $179.1 - $20 = $159.1

evaluate-a-function f(x) = [tex]\frac{x}{7}[/tex] f(7) =
Step-by-step explanation:
Hey there!
f(x) = 7/x
~ Simply keep the "7" in the place where "x" is there.
[tex]f(7) = \frac{7}{7} [/tex]
Therefore, X= 1.
Hope it helps....
Answer:
After evaluating the function [tex]f(x)=\frac{x}{7}[/tex] by putting x = 7, we get f(7)= 1
Step-by-step explanation:
We need to evaluate the function [tex]f(x)=\frac{x}{7}[/tex] and find f(7)
For finding f(7) we will put x = 7 in the given function [tex]f(x)=\frac{x}{7}[/tex]
So, putting x= 7 and finding f(7)
[tex]f(x)=\frac{x}{7}\\Put\:x=7\\f(7)=\frac{7}{7}\\f(7)=1[/tex]
So, after evaluating the function [tex]f(x)=\frac{x}{7}[/tex] by putting x = 7, we get f(7)= 1
