x = 4/5 = 0.8
y = (4/x * x) + √x + 0.2 - 5x.
First, let's plug 0.8 in for x
y = (4/0.8 * 0.8) + √0.8 + 0.2 - 5(0.8)
(4/0.8 * 0.8) the 0.8s cancel out leaving just 4
y = 4 + √0.8 + 0.2 - 5(0.8)
5 * 0.8 = 4
y = 4 + √0.8 + 0.2 - 4
Add all the terms together
y = 1.09.
Answer:
24 total students
Step-by-step explanation:
multiply 25 times 18 to get 450 then divide 450 by 75 then you get 6, which is the total amount of girls, so 6 + 18 = 24
29
I hope this helps!

Answer:
x^3 - 8
Step-by-step explanation:
By solving a system of equations, we will see that m measures 12 units.
<h3>
How to get the measure of m?</h3>
Notice that we have 3 right triangles.
Then we can write the equations:
cos(a) = 6/m
For the small triangle on the left, where m is the hypotenuse.
cos(a) = m/(6 + 18)
For the larger triangle (the one composed of the two triangles).
Where in both equations, angle "a" is the one in the top left.
Then we have the system of equations:
cos(a) = 6/m
cos(a) = m/(6 + 18)
Then we can write:
6/m = m/(6 + 18)
If we simplify the expression, we get:
6*(6 + 18) = m^2
6*(24) = m^2
144 = m^2
√144 = m = 12
Then we conclude that m measures 12 units.
