Answer:
Step-by-step explanation:
a+pR^2-2pr^2, since R=15 and r=7.5
A=225p-112.5p
A=112.5p
a= 353.25ft^2
Part A: 7n+6
Part B: By verbal do you mean like Three times N plus Eight ?

Answer: 25 and 22
Step-by-step explanation:
Since one number is 3 bigger than the other, we can call them x, and x-3.
Then we know that the sum of 3 times x and 2 times (x-3) is equal to 19, so we can make the equation
3x+2(x-3)=19
Simplifying would get you
3x+2x-6=19
adding the x's and adding six to both sides of the equations gets you
5x = 25
divide by 5 and
x=5
Put those numbers back into your previous labels for them, x and x-3, and you get 5 and 2
Hope this helps
Answer: ok what is it
Step-by-step explanation:
Jessica's annual salary is $68571.43.
Data;
- percentage saved for housing = 28%
- amount saved annually = $1600
<h3>Percentage</h3>
This is the ratio of a number to the entire value and multiplied by 100
The percentage set aside for housing is given as 28% which is $1600.
Let find 28% of x which is equal to 1600

cross multiply both sides and solve for x

Divide both sides by the coefficient of x

Her monthly income is $5714.28.
Let's multiply this by 12 (months in a year) to determine her gross monthly income.

From the above calculations, Jessica's annual salary is $68571.43.
