Keenan measured a community college and made a scale drawing. The scale of the drawing
was 1 centimeter : 9 meters. If the actual width of a building at the college is 90 meters, how
wide is the building in the drawing?
Answer:
The answer is 10 centimeters
Step-by-step explanation:
If 1 cm on the map = 9 meters. 10cm would be 90 meters. Hope this helps!
Answer:
drawing = 10 cm for the width.
Step-by-step explanation:
1 cm / 9 m = x / 90 m
If the meters go on the bottom in the left ratio, they must go on the bottom on the right ratio. In this case the cm is the unknown and it must go on the top with no units.
Cross multliply
9 m * x = 90m * 1cm
Divide by 9
9m * x/ 9m = 90 m * 1 cm / 9m Notice the units (m) cancel out
x = 10 cm

Identify the model that shows 4 items being divided equally among 3 people. How much will each person have
Answer:
1 1/3 items
Step-by-step explanation:
Total number of items = 4 items
Total number of people = 3 people
4 items = 3 people
To know the number of items each person will get, we can write;
x items = 1 person
Divide both expressions
4/x = 3/1
3x = 4
x = 4/3
Express as mixed fraction;
4/3 = 1 1/3
Hence each person will receive 1 1/3 items

Solve each equation using substitution. Answers are on the right and questions are on the left.
Answer:
Q1. No solutionQ2. (5, 6)Q3. Infinitely many solutionsQ4. No solutionQ5. (2, 3)Step-by-step explanation:
Q1.
y = -1/3x - 1x + 3y = -12Solution
x + 3(-1/3x - 1) = -12x - x - 3 = -12-3 = -12No solution
Q2
y = 2x - 4y = x + 1Solution
2x - 4 = x + 1x = 5y = 6(5, 6)
Q3
y = -3x + 36x + 2y = 6Solution
6x + 2(-3x + 3) = 66x - 6x + 6 = 66 = 6Infinitely many solutions
Q4
- 5x + y = 1- 10x + 2y = -2 ⇒ -5x + y = -1Solution
1 = -1No solution
Q5
y = 1/2x + 2y = x + 1Solution
1/2x + 2 = x + 11/2x = 1x = 2y = 3(2, 3)

Simplify the expression by using the distributive property.
-2(4x - 10)
Answer:
-8x+20
Step-by-step explanation:
multiply using the distributive property:)
Answer:
[tex]\huge\boxed{\boxed{-8x+20}}[/tex]
Step-by-step explanation:
Hello.
Please remember that the Distributive Property states that
a(b+c)=ab+ac
Now, simplify:
-2(4x-10)
multiply -2 times 4x and -10:
-8x+20 (a negative times a negative equals a positive only)
And we're done!
I hope it helps & have an outstanding day!

Solve the equation by factoring.
c2 - 2c + 1 = 0
Answer:
The only solution is c=1
Step-by-step explanation:
c^2 - 2c + 1 = 0
What 2 numbers multiply to 1 and add to -2
-1 * -1 =1
-1 + -1 =-2
( c-1) (c-1)=0
Using the zero product property
c-1 =0 c-1 =0
c=1 c=1
The only solution is c=1

If 7x−6y=2 and −2x−y=3 are true equations, what would be the value of 5x−7y?
Answer:
-55
Step-by-step explanation:
7x-6y=2
-2x-y=3
by substitution method
y=3+2x
7x-6(3+2x)=2
7x-18-12x=2
-5x=20
x=-4
-2(-4)-y=3
8-y=3
-y=3-8
y=5
therefore the value of x=4 and that of y=5
5x-7y=5(-4)-7(5)
=-20-35
=-55

Answer:
3 laps.
Step-by-step explanation:
Hi! I can see how this is tricky, but I was a bit confused by the 4 in "If she runs 4." It says in the problem that the track is a mile long... So if you run the track 3 times, 3 x 1 = 3.
