Calculate the area of a square with sides of 5 inches.
Answer:
A = 25 in²
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASGeometry
Area of a Square: A = x²Step-by-step explanation:
Step 1: Define
Side length = 5 in
Step 2: Solve for A
Substitute: A = (5 in)²Evaluate: A = 25 in²And we have our final answer!
Answer:
25 inches squared.
Step-by-step explanation:
Since we know a square has 4 sides of equal length, and one of the sides has been given to us (5 inches), it's safe to assume the rest of the sides are the same. To find the area, we multiply length x width (5 x 5) to get 25 inches squared. Hope this helps! xx

A class has 30 students. 18 are boys. what id the ratio of boys to girls? (you must simplify)
Answer:
number of students =30
boys =18
girls =30-18=12
therefore,the ratio of boys :girls
=18:12
then simpilyfing, =3:2
The ratio of the number of boys to girls in the class is 3 : 2
Total number of students = 30
Number of boys = 18
Nunber of girls = 30 - 18 = 12
The ratio of boys to girls :
Number of boys : Number of girls 18 : 12Simplify to lowest term :
Divide both sides by 63 : 2Therefore, the ratio of boys to girls is 3 : 2

8. The coordinates (0,0) represent the fact that when 0 minutes has passed, the horses have gone 0 miles because they hadn't started yet.
9. From the graph, it looks like horse A takes 4 minutes and horse B takes 2.5 minutes (aka 2 minutes and 30 seconds) to travel 1 mile.
10. For A: y = (1/4)x
For B: y = (2/5)x
11. For A: 3 miles
For B: (24/5) miles, or 4 and (4/5) miles.
12. Can't see the entire problem sorry.
Step-by-step explanation:
9. You find this by going to y=1 and look towards the right till you find the point the line intersects with y=1. Then find the x value by finding the corresponding number on the x axis.
10. A linear function will look something like this: y = mx+b, where y is the y value, x is the x value, m is the slope, and b is the y-intercept. Since both lines start from 0, you don't have to write the y-intercept since there's no point in writing +0. To find slope, you find delta y over delta x. Basically just find the difference of two y values and the difference of two x values from the same coordinate in the same order. I know that sounds really confusing but your teacher will probably teach this later on.
11. x represents the time, so just substitute x as 12 in the equation.

Step-by-step explanation:
Simplify the following:
x^2 + 6 x + 3 + 4/x
Put each term in x^2 + 6 x + 3 + 4/x over the common denominator x: x^2 + 6 x + 3 + 4/x = x^3/x + (6 x^2)/x + (3 x)/x + 4/x:
x^3/x + (6 x^2)/x + (3 x)/x + 4/x
x^3/x + (6 x^2)/x + (3 x)/x + 4/x = (x^3 + 6 x^2 + 3 x + 4)/x:

For a concert 5,000 tickets were sold, and the proceeds were $72,000. Tickets for children 16 and younger were $10, adults were $20, and seniors 60 and older were $15. There were 3 times more children than seniors at the concert. What system of equations represents the number of children, c, adults, a, and seniors, s, that attended the concert?
Answer:
The answer is:
[tex]( c + a + s) = 5000\\\\(10c + 20a + 15s) = 72000\\\\c = 3s[/tex]
Step-by-step explanation:
Ticket number sold = 5000
Ticket revenue Selling = 72,000 dollars
Kids 16 and younger tickets = $10
adults=$20
senior citizens= 60
Old = $15
Let:
Children's number, c ;
Ownership, a;
The aged, s,
Also at the event, there were 3 times many more kids as the senior citizens; c=3 total amount attendees= 5000
5,000= (c + a + s)
Total wages or income
72000= (10c + 20a + 15s)

Which equation is equivalent to 7-2(3x+4)=8x
A -6x+15=8x
B-6x-1=8x
C15x+20=8x
The equation that is equivalent to the expression 7-2(3x+4)=8x is
-6x - 1 = 8x.
Option B is the correct answer.
We have,
To find the equation that is equivalent to 7-2(3x+4)=8x, simplify the given equation by applying the distributive property and combining like terms.
7 - 2(3x + 4) = 8x
First, distribute the -2 to the terms inside the parentheses:
7 - 6x - 8 = 8x
Combine like terms:
-6x - 1 = 8x
Thus,
The equation that is equivalent to the expression 7-2(3x+4)=8x is
-6x - 1 = 8x.
