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)

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
