Solve for x. 25 - 3x = -5(1 - x) - 2x
grandymaker [24]

Answer:

x = 5

Step-by-step explanation:

25 - 3x = -5(1 - x) - 2x

<u></u>

<u>We have to first get rid of the parenthesis:</u>

-5 * 1  ==>  -5

-5 * -x  ==>  5x

<u>So now you should have:</u>

25 - 3x = -5 + 5x - 2x

<u>Combine like terms:</u>

25 - 3x = -5 + 5x - 2x

25 - 3x = -5 + 3x

<u>Add 3x to both sides:</u>

25 - 3x  =  -5 + 3x

    + 3x  =      + 3x

<u>And you should have:</u>

25 = -5 + 6x

<u></u>

<u>Add 5 to both sides:</u>

25 = -5 + 6x

+5 = +5

30 = 6x

<u>Divide 6 to both sides:</u>

\frac{30}{6}     =      \frac{6x}{6}

5 = x

PLEASE HELP ASAP GEOMETRY 20 PTS REAL ANSWERS ONLY
kodGreya [7K]

Answer:

Step-by-step explanation:

Use the Law of Cosines to find the measure of angle A from the lengths of the sides.

A = arccos[(b²+c²-a²)/(2bc)] ≅ 29.9°

B = arccos[(a²+c²-b²)/(2ac)] ≅ 54.8°

C = 180 - A - B = 95.3°

Answer both question for 20 points and brainliest
Dmitrij [34]

Answer:

1 - c

2 - A

Step-by-step explanation:

Hey There!

So for the first one we are given the dimensions of a rectangular prism and they want us to find the volume

Remember to find the volume we use the equation

V = length x width x height

so we just plug in the values

v = 2.6 x 2.1 x 3.9 = 21.294

the closest is 20 so C is your answer

For the second one we are given a triangular prism

and they want us to find the volume

V=\frac{1}{2} bhl

b = base (10.3)

l = length (4)

h = height (7)

7x4=28

28x10.3=288.4

then we divide by 2

288.4/2=144.2

so your selected answer is correct
