Part A is a rational number, so adding another rational number (1/3) gives a rational result.
Part B is 2/3, so adding 1/3 gives a sum of 1, which is still a rational number.
Part C is 2*pi, which is irrational, and adding 1/3 gives a sum of 2*pi + 1/3, which still cannot be simplified into a rational expression.
Part D is an irrational number, and 1/3 - sqrt(17) also cannot be simplified into a rational number, so this is irrational.

Therefore the correct answers to this are C & D.

5/8 - 3/10 A. 13/40 B. 1/20 C. 1/4 D. 1/5

5/8 - 3/10

Find the common denominator:

Multiples of 8: 8, 16, 24, 32, 40 (8 x 5 = 40)

Multiples of 10: 10, 20, 30, 40 (10 x 4 = 40)

5/8 = 5*5 / 8*5 = 25/40

3/10 = 3*4 / 10 *4 = 12/40

Now you have 25/40 - 12/40

25 -12 = 13

Answer = 13/40

The answer is A.

1. h(2) + g(2) * h(t) = 3-5 g(t) = 2t - 5

kap26 [50]

Answer:

h(2)+g(2) = -3

Step-by-step explanation:

$h(2) +g(2)\\ \\h(t) = 3-5, g(t) = 2t -5$

Replace the variable (t) with (

2) in the expression.

h (2) = 3 - 5

Replace the variable (t) with (

2) in the expression.

g(2) = 2(2) -5

Replace the function designators in h(2) +g(2) with the actual functions.

h(t) = 3 - 5 +2 (2) ← plug h(2) into 2(t)

Remove parentheses.

3 - 5 + 2(2)

Multiply 2 by 2

3 - 5 + 4 - 5

Subtract 5 from 3

-2 + 4 - 5

Add -2 and 4

2 - 5

Subtract 5 from 2

-3
