What is the value of a?<br><br> 5(a-4)-8a=55? <br> Please help :)

Ad libitum [116K]

If you want to calculate 5*(a-4) - 8*a = 55, you have to do few steps to get to know the value of the a.

5*a - 20 - 8*a = 55
-3*a = 55 + 20
-3*a = 75 /(-3)
a = - 25

The correct result and the value of the a is -25.

Express 3.023 in P form where p and q are integers and q= 0 D

AnnZ [28]

Given:

The number is 3.023.

To find:

The given number in the form of $\dfrac{p}{q}$ , where $q\neq 0$ .

Solution:

The given number is 3.023. It can be written as:

$3.023=3.023\times \dfrac{1000}{1000}$

$3.023=\dfrac{3023}{1000}$

It cannot be simplified further because 3023 and 1000 have no common factors.

Therefore, the given number 3.023 can be written as $\dfrac{3023}{1000}$ .

Triangle ABC has side lengths a= 24, b= 40, and c= 55. What is the measure of angle C? 83.6° 116.2° 23.0° 40.7°

Harlamova29_29 [7]

<h3>Answer: 116.2°</h3>

Work Shown:

$c^2 = a^2 + b^2 - 2ab\cos(C)\\\\55^2 = 24^2 + 40^2 - 2*24*40\cos(C)\\\\3025 = 576 + 1600 - 1920\cos(C)\\\\3025 = 2176 - 1920\cos(C)\\\\3025 - 2176 = -1920\cos(C)\\\\849 = -1920\cos(C)\\\\-1920\cos(C) = 849\\\\\cos(C) = (849)/(-1920)\\\\\cos(C) \approx -0.4421875\\\\C \approx \cos^{-1}(-0.4421875)\\\\C \approx 116.243535748231^{\circ}\\\\C \approx 116.2^{\circ}\\\\$

The first equation is one of the three variations for the Law of Cosines.

Make sure your calculator is in degree mode.
