In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, The ratio of boys to girls in Ella's class is 3 to 4. The ratio of boys to girls in Minh's class is 4 to 5.

Each class has a total of 20 girls and assuming each class has a total of x students.

∴ 4x/7 = 20.

4x = 140.

x = 35.

No. of boys = 15.

5x/9 = 20.

5x = 180.

x = 36.

No. of boys = 16.

I believe the measurement of angle 5, would be 114.

Step-by-step explanation:

We can solve this by using alternate interior angles. First we must find the other alternate interior angle for angle 5. To do this we take 66 and subtract it from 180. We now find that the angle adjacent to the angle measuring 66 degrees is equal to 114 degrees.  Now, the angle we just found the measurements for, is the alternate interior angle for angle 5. Therefore, since they are alternate interior angles, angle 5 is equal to 114 degrees.

Answer:

(-2,3)

Step-by-step explanation:

Multiply -3x+4y=18 with 2:

-6x+8y=36

Add -6x+8x=36 and 6x+2y=-6

10y=30

y=3

So y=3 we can replace y with 3 on any of these two equations:

6x+6=-6

Move the 6 to the other side:

6x=-12

x=-2

So the solution is

(-2,3)
