PLEASE HELP WILL GIVE BRAINLIEST
Marta_Voda [28]

<u><em>Answer:</em></u>

The bird will have traveled 403 meters in 13 seconds if it maintained a speed of 31 m/sec

<u><em>Explanation:</em></u>

<u>The equation that relates velocity, distance and time is:</u>

velocity = \frac{distance}{time}

<u>This means that:</u>

distance = velocity * time

<u>In the given, we have:</u>

velocity = 31 m/sec

time = 13 sec

<u>Substitute with the givens in the above equation and solve for the distance as follows:</u>

distance = velocity * time

distance = 31 * 13

distance = 403 meters

Hope this helps :)

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}

Furkat [3]

Answer: =4.4n-13

Step-by-step explanation:

Let's simplify step-by-step.

2n−9−(−2.4n+4)

Distribute the Negative Sign:

=2n−9+−1(−2.4n+4)

=2n+−9+−1(−2.4n)+(−1)(4)

=2n+−9+2.4n+−4

Combine Like Terms:

=2n+−9+2.4n+−4

=(2n+2.4n)+(−9+−4)

=4.4n+−13
