Hi there! 

Question 6) 

The scale is 1 cm : 18km. 

This means that for every 1 cm, there is 18 km

So, we are going to set it up like a proportion:

cm    1      9
km     18   x

Now we are going to cross multiple: 

1*x=9*18 

Solve for x: 
 x=152

Therefore, the answer is 152 km

question 8) 

Yet again we have a proportion problem. 
 
15    10
18      x

15x=180

x=12ft

Therefore, the answer is 12 feet.


Question 10) 

This question is just like the other one!

3.   6
7.    x

3x=42

x=14

Therefore, the answer is 14 feet

PLEASE HELP WITH 37 IM MARKING BRAINLIEST TO THE CORRECT ANSWER
Maru [420]

Answer:

Infinitely many solutions

Step-by-step explanation:

-5.9x - 3.7y = -2.1

5.9x + 3.7y = 2.1

If we add these two equations together, -5.9x cancels out 5.9x, -3.7y cancels out 3.7y, and -2.1 cancels out 2.1.

This leaves us with:

0 = 0

Since this is true, that means there are infinite solutions.

Solve the system. <br> y= -2x + 1<br><br> y= 2x - 3
Neporo4naja [7]

Equation 1: y = -2x + 1

Equation 2: y = 2x - 3

Since both equations already have y isolated, we are able to simply set the right side of both equations equal to each other. Since we know that the value of y must be the same, we can do this.

-2x + 1 = 2x - 3

1 = 4x - 3

4 = 4x

x = 1

Then, we need to plug our value of x back into either of the original two equations and solve for y. I will be plugging x back into equation 2 above.

y = 2x - 3

y = 2(1) - 3

y = 2 - 3

y = -1

Hope this helps!! :)
