i believe the formula of d = rt is more useful in form of d/ r = t when you need to

determine the time if it takes to travel a certain distance of a certain speed.

8/5 ( 2x + 13 ) - 3 = 22

Alona [7]

Answer:

$x = \frac{21}{16}$ = 1 5/16

[/tex] 1 \frac{5}{16}[/tex]

Step-by-step explanation:

$\frac{8}{5} (2x + 13) - 3 = 22$

Expand

$\frac{16}{5} x + \frac{104}{5} - 3 = 22 \\ \frac{16}{5} x + \frac{89}{5} = 2$

Collect like terms and simplify

$\frac{16}{5} x = 22 - \frac{89}{5} \\ \frac{16}{5} x = \frac{21}{5}$

Cross Multiply

$80x = 105$

Divide both sides of the equation by 80

$\frac{80x}{80} = \frac{105}{80} \\ x = \frac{21}{16}$

Factor completely 81x8 − 1. (9x4 − 1)(9x4 + 1) (3x2 − 1)(3x2 + 1)(9x4 − 1) (3x2 − 1)(3x2 + 1)(9x4 + 1) (3x2 − 1)(3x2 + 1)(3x2 +

denis-greek [22]

Answer:

(3x^2 - 1)(3x^2 + 1)(9x^4 + 1).

Step-by-step explanation:

Using the identity for the difference of 2 squares;

a^2 - b^2 = (a - b)(a + b)

we put a^2 = 81x^8 and b^2 = 1 giving

a = 9x^4 and b = 1, so:

81x^8 − 1 = (9x^4 - 1)(9x^4 + 1)

Applying the difference of 2 squares to 9x^4 - 1:

= (3x^2 - 1)(3x^2 + 1)(9x^4 + 1).

10 oz of salmon is needed for 16 servings

20 oz of salmon is needed for 32 servings

50 oz of salmon needed for 80 servings

62.5 oz of salmon needed for 100 servings

<em><u>Solution:</u></em>

Given that,

One roll can be cut into 8 servings

The ingredients for one roll include sushi rice, seaweed sheets, cucumbers, cream cheese, and 5oz of smoked salmon

1 roll is 8 servings and it is made of 5 oz of smoked salmon

Which means that, 5 oz of smoked salmon is needed fo 8 servings

Write an expression for the amount of salmon needed to make s serving of sushi

$Amount\ of\ salmon = \frac{5}{8}s$

Where, s = serving

<h3><u>How much salmon is needed to make ?</u></h3><h3><u>16 servings</u></h3>

$Amount\ of\ salmon = \frac{5}{8} \times 16 = 5 \times 2 = 10$

Thus 10 oz of salmon is needed for 16 servings

<h3><u>32 servings</u></h3>

$Amount\ of\ salmon = \frac{5}{8} \times 32 = 5 \times 4 = 20\ oz$

Thus 20 oz of salmon is needed for 32 servings

<h3><u>80 servings</u></h3>

$Amount\ of\ salmon = \frac{5}{8} \times 80 = 5 \times 10 = 50\ oz$

Thus 50 oz of salmon needed for 80 servings

<h3><u>100 servings</u></h3>

$Amount\ of\ salmon = \frac{5}{8} \times 100 = 5 \times 12.5 = 62.5\ oz$

Thus 62.5 oz of salmon needed for 100 servings
