Answer: 30
Step-by-step explanation: Assuming that the side lengths correspond with one another you can set up a ratio to solve
It should look something like this: 15/25 = 18/x
With this equation set up you can solve by cross multiplying. 25(18)=15x
Then start sloving:
25(18)=15x
450=15x
450/15=15x/15 (divide both sides by 15)
30=x
What is...
1. 4x = -36
2. 5x - 15 = 50
3. 4(x + 2) - 17 = 35
4. 6x + 12 = 4x - 18
5. 1/2 (4x - 10) + 5 = x - 11
Step-by-step explanation:
1Ans: 4x = -36
× = -36/4
× = -9
2Ans: 5x -15 = 50
5x = 50 + 15
5x = 65
x = 65/5
x = 13
3Ans: 4(x + 2) -17 = 35
4x +8 -17 = 35
4x -9 = 35
4x = 35 +9
4x = 44
x = 44/4
x = 11
4Ans: 6x +12 = 4x -18
6x -4x = -18 -12
+2x = -30
x = -30/+2
x = -15
5Ans: 1/2 (4x -10) +5 = x -11
0.5 (4x -10) +5 = x -11
2x -5 +5 = x -11
2x = x -11
2x - x = -11
1x = -11
x = -11/1
x = -11

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)

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

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
