Solve -2(5x – 3) = 41. need help

navik [9.2K]3 years ago

Answer:

x = -7/2

Step-by-step explanation:

-2(5x - 3) = 41

Distribute the -2 inside the parenthesis.

-10x + 6 = 41

Subtract 6 from both sides.

-10x = 35

Divide both sides by -10.

x = 35/-10

Simplify the fraction.

x = -7/2.

Proof:

-2(5x - 3) = 41

Substitute variable.

-2(5(-7/2) - 3) = 41

Multiply 5 and -7/2.

-2(-35/2 - 3) = 41

Turn 3 into a fraction with denominator 2.

-2(-35/2 - 6/2) = 41

Subtract 6/2 from -35/2.

-2(-41/2) = 41

Multiply -2 and -41/2.

41 = 41.

PLEASE SOMEONE HELP ME WITH THESE MATH QUESTIONS!!! *VERY URGENT* *IF YOU ANSWER CORRECTLY, YOU'LL GET 10 POINTS!*
Tasya [4]

Answer:

Question 21: C.

Question 22: I.

Question 23: E.

Question 24: B.

Step-by-step explanation:

#21: The first statement is presented in the "Given" section.

#22: Since the reflexive property states that anything is equal to itself, BC ≅ BC.

#23: C being the midpoint of AD means that C is the same distance from both point A and point D. This then means that AC ≅ CD.

#24: AB ≅ DB due to the given, BC ≅ BC (since it's the same side), and we've proven that AC ≅ CD using a midpoint. We've proven <em>all three sides</em> on the two triangles to each other are congruent. This means that we've proven the triangles using SSS, which is B.

The mean absolute deviation of the set of numbers is 5/4

<h3>How to determine the mean absolute deviation?</h3>

The set of numbers is given as:

1 1/2, 0, 4 and 2 1/2

Rewrite the set of numbers as:

1.5, 0, 4 and 2.5

Calculate the mean of the set using:

\bar x = Sum/Count

So, we have:

\bar x = (1.5 + 0 + 4 + 2.5)/4

Evaluate

\bar x = 2

The mean absolute deviation is then calculated as:

M.A.D = 1/n * ∑|x - \bar x|

So, we have:

M.A.D = 1/4 * [|1.5 - 2| + |0 - 2| + |4 - 2| + |2.5 - 2|]

Evaluate the absolute difference

M.A.D = 1/4 * [0.5 + 2 + 2 + 0.5]

Evaluate the sum

M.A.D = 1/4 * 5

Evaluate the product

M.A.D = 5/4

Hence, the mean absolute deviation of the set of numbers is 5/4
