Answer:
1 : 120
Step-by-step explanation:
Given that ;
Actual width = 30feets
Width in drawing = 3 inches
Recall :
1 foot = 12 inches
Actual width in inches : (30 * 12) = 360 inches
Comparing actual width to drawing width
3 inches : 360 inches
1 : 120
Scale used is :

Solve the system of equations:
2x + 3y = 10
x - 2y = -2
(2,1)
(0,1)
(0,2)
(2,2)
No solution
Answer:
(2,2)
Step-by-step explanation:
2x+3y=10
x−2y=−2
In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.
2x+3y=10,x−2y=−2
To make 2x and x equal, multiply all terms on each side of the first equation by 1 and all terms on each side of the second by 2.
2x+3y=10,2x+2(−2)y=2(−2)
Simplify.
2x+3y=10,2x−4y=−4
Subtract 2x−4y=−4 from 2x+3y=10 by subtracting like terms on each side of the equal sign.
2x−2x+3y+4y=10+4
Add 2x to −2x. Terms 2x and −2x cancel out, leaving an equation with only one variable that can be solved.
3y+4y=10+4
Add 3y to 4y.
7y=10+4
Add 10 to 4.
7y=14
Divide both sides by 7.
y=2
Substitute 2 for y in x−2y=−2. Because the resulting equation contains only one variable, you can solve for x directly.
x−2×2=−2
Multiply −2 times 2.
x−4=−2
Add 4 to both sides of the equation.
x=2
The system is now solved.
x=2,y=2

A square has the area of 25 square inches. What is that perimeter of a triangle with all equal sides if each of its sides is twice as long as the side of the square?
Answer: 30 inches
Step-by-step explanation:
The sides of the square are equal and so if the area is 25 inch², each side can be acquired by square rooting that figure:
= √25
= 5 inch per side for the square
Each side of the triangle is twice as long as a side of the square:
= 5 * 2
= 10 inches
There are three sides to a triangle so the perimeter is:
= 10 * 3
= 30 inches
Candice is decorating a ballroom ceiling with garland. The width of the rectangular ceiling is 30 meters and the diagonal distance from one corner to the opposite corner is 34 meters. How much garland will Candice need for the length of the ceiling
Answer:
16 meters
Step-by-step explanation:
Candice is decorating a ballroom ceiling with garland. The width of the rectangular ceiling is 30 meters and the diagonal distance from one corner to the opposite corner is 34 meters. How much garland will Candice need for the length of the ceiling
The formula to solve for the above question is:
Diagonal² = Width² + Length²
34² = 30² + L²
Collect like terms
L² = 34² - 30²
L = √34² - 30²
L = √(256)
L = 16 meters
Therefore, the length of the ceiling is 16 meters

Steve started with $250 and spent $20 per week. Chelsea started with nothing but saved $30 per week. Use x for time and y for savings.
Write an equation to represent Steve's situation.
Answer:
[tex]250 - 20x=y[/tex]
Step-by-step explanation:
As per the given problem, Steve starts with $250, and spent $20 a week, the problem mentions nothing about Steve's savings, therefore, one can assume that they didn't save anything. As the problem requests, parameter ([tex]x[/tex]) will be used for the time, and ([tex]y[/tex]) for the savings.
Steve's saving would be equal to his initial value, minus his expense, in essence;
[tex]250 - 20x=y[/tex]
The initial value, minus the amount spend per week multiplied by the week number will equal the savings left.
Answer:
y=250-(20x)

a sandwich store charges $10 delivery fee and $4.50
b. what is the total cost for x sandwiches ?
Answer:
Step-by-step explanation:
a sandwich store charges $10 delivery fee and $4.50
b. what is the total cost for x sandwiches ?
total cost equals the cost of the sandwiches plus the delivery fee
one sandwich cost $4.50
x number of sandwiches cost x times $4.50 or $4.50(x)
delivery fee = $10
total cost equals the cost of the sandwiches plus the delivery fee
total cost = $4.50(x) + $10
total cost = $4.50(x) + $10
A type of electric car can travel 3 miles on 1 kilowatt hour of electricity. How many kilowatt hours of electricity would it take to drive electric car to 's house and back? Lives miles from .
Answer:
Question is incomplete so I'll use a reference.
Assume the person whose house the car went to is 21 miles away.
The car would have had to go back and forth so the total distance spent would be:
= 21 + 21
= 42 miles
The car uses 1 kilowatt hour to go 3 miles. Now it has to go 42 miles.
The number of kilowatt hours it will need are:
= Distance / distance per kilowatt hour
= 42 / 3
= 14 kilowatt hours

What is the answer 3x-5=2x-1
Answer:
x=4
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
3x - 5 = 2x -1
Add 5 to both sides
3x - 5 + 5 = 2x - 1 + 5
3x = 2x + 4
Subtract 2x form both Sides
3x - 2x = 2x - 2x + 4
x = 4

How many packages of diapers can you buy with $40 if one package costs $8?
Write and solve an equation for the above situation. Use "p" as the variable
Answer:
Step-by-step explanation:
Im not sure about the first two about fraction bars, a fraction bar looks like this 1/10 or 4/9, maybe the question is asking you to make a fraction of each side so that they both equal the same thing using common denominators.
In that case #2 would be 21/3= 21/7
still not sure about #1
X+32=40
subtract 32 on each side
x+32-32=40-32
