Evaluate each expression if x is latex: \frac{2}{5}2 5, y is -4, and z is -0.2.

x+y

2x−z

x+y+z

y⋅x

x + y = - 3.6

2x - z = 1

x + y + z = - 3.8

y - x = - 4.4

Step-by-step explanation:

We have to evaluate the given expressions of x, y, and z where, , y = - 4 and z = - 0.2.

So, x + y = 0.4 + (- 4) = - 3.6

And, 2x - z = 2(0.4) - (- 0.2) = 1

And, x + y + z = 0.4 - 4 - 0.2 = - 3.8

Finally, y - x = - 4 - 0.4 = - 4.4 (Answer)

13.33%

say 50 oranges, then 100 apples

80 are red, 20 are yellow

total fruit = 150

20chances out of 150 for yellow

20/150 = 13.33%
