There are 15 boys in Ella's class and 16 boys in Minh's class.

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.

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.

Answer:

D

Step-by-step explanation:

7x - 4 = -18            (add 4 to both sides)

7x = -14                  (divide both sides by 7)

x = -2

the answer is D

Considering that all quadrilaterals are squares. When x varies 1 unity, y varies 5 units. So the slope is 5.

Answer:

the answer is D

Step-by-step explanation:

slope=rise÷run

from point A to B 1 right and 5 up, so both are positive

rise is up or down

run is left or right

slope=5÷1=5

so the answer is D

Answer:

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: f(2)=1

Step-by-step explanation:

This is a function-related problem. In order to solve f(2), you need to substitute the value into the original function.

-----------------------------------------------------------------------------------------

f(x)=5x⁵-3x⁴- 17x³-4x²+10x+21

f(2)=5(2)⁵-3(2)⁴- 17(2)³-4(2)²+10(2)+21

f(2)=160-48-136-16+20+21

f(2)=1

Step-by-step explanation:

y=mx+b where m=slope and b=y-intercept.

Answer:

6

Step-by-step explanation:

Slope-intercept form is written y=mx+b.

y= always by itself (in slope-intercept form)

m= the slope (in this case, 6)

x= the letter that the slope is always next to

b= the y-intercept

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)
