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

Leiff goes online to buy a new video game. He finds a site that currently has a promotion of 15% off on all orders over $50. Lei
White raven [17]
If the original price tag of the video game is $128, to get its discounted price at 15%, that means what Leiff paid for was (100-15) = 85% of the original price. So, the price of the video game then becomes (0.85 x 128) = $108.80. Since Leiff has to pay an additional 5.3% of the new price, that's (100 + 5.3) = 105.3% of the new price which is (1.053 x 108.8) = $114.57 Adding the shipping fee for the videogame, 114.57 + 4.75 = $119.32 Thus, the total price is <span>$119.32</span>

Ray delivered 3/8 of the newspapers on his route in the first hour and 4/5 of the rest in the second hour what fraction of the n
Temka [501]

Answer:

\frac{1}{2}

Step-by-step explanation:

Let the total number of Newspapers be x

Number of newspapers delivered in first hour of his route= \frac{3}{8} of x

Total number of newspapers delivered in first hour= \frac{3}{8}x

Number of newspapers left= x-\frac{3x}{8}

Number of newspapers left=\frac{8x-3x}{8}

Number of newspapers left=\frac{5x}{8}

Number of newspapers delivered in second hour=4/5 of\frac{5x}{8}

Number of newspapers delivered in second hour=\frac{x}{2}

Fraction of newspapers delivered in second hour is=\frac{1}{2}

Hence, the correct answer is \frac{1}{2}
