A Student Would Write An Equation Such As 2x + 38 = 90 For Which Set Of Angles?SSuch As 2x + 38 = 180

Answers

Answer 1

Answer:

Figure (c)

Step-by-step explanation:

a). Angles in the figure attached are the linear pair of angles.

    Since, sum of the linear pair of angles is 180°.

    2x + 38 = 180°

b). Angles given in this figure are the vertically opposite angles.

   Since, vertically opposite angles are equal in measure.

   2x = 38°

c). There are three angles given the picture.

   Since these angles are formed at a point of a line, sum of angles will be 180°.

   90° + 38° + 2x = 180°

   2x + 38 = 180 - 90

   2x + 38 = 90°

Therefore, figure (c) shows the equation.

What does this equal too(2x-5)^2

Answers

Answer:

4x² - 20x + 25

Step-by-step explanation:

(2x-5)² means (2x-5)(2x-5)

Expand the brackets.

1. do 2x times 2x = 4x²

2. do 2x times -5 = -10x

3. -5 times 2x = -10x

4. -5 times -5 = 25

Altogether it is 4x² - 10x - 10x + 25

This simplifies to 4x² -20x + 25.

4 - 3|x + 1| < -17

Answers

Answer: x > 6, x < -8

Subtract 4 from both sides.

−3∣x+1∣<−17−4

Then simplify -17 - 4 to -21.

−3∣x+1∣<−21

Divide both sides by −3.

|x + 1| > -21/-3

Two negatives make a positive.

|x + 1| > 21/3

simplify 21/3 to 7

Break down the problem into these 2 equations.

x + 1 > 7

-(x + 1) > 7

Solve the 1st equation: x + 1 > 7

x > 6

Solve the 2nd equation: -(x + 1) > 7

x < -8

last collect all solutions

Given is a proof for the congruence of the lines HG and EG.

Given,

G is the midpoint of KF.

KH ∥ EF

Triangles F E G and K H G are connected at point G.

We have to prove HG ≅ EG.

From the given steps of proof,

we get two angles and the included side of triangle FEG is congruent to corresponding two angles and the included side of triangle KHG.

So by ASA theorem both triangles are congruent.

Hence the missing reason is ASA.

3x - 17 = 2x + 35
Please help

Answers

Answer:

[tex]x = 52[/tex]

Step-by-step explanation:

We have the following equation:

[tex]3x -17=2x+35[/tex]

First we simplify the numbers.

[tex]3x -17+17=2x+35+17[/tex]

[tex]3x=2x+52[/tex]

[tex]3x-2x=2x-2x+52[/tex]

[tex]x=52[/tex]

Answer:

x = 52

General Formulas and Concepts:

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define equation

3x - 17 = 2x + 35

Step 2: Solve for x

Subtract 2x on both sides:                           x - 17 = 35Add 17 to both sides:                                    x = 52

Step 3: Check

Plug in x to verify it's a solution.

Substitute:                         3(52) - 17 = 2(52) + 35Multiply:                             156 - 17 = 104 + 35Subtract/Add:                    139 = 139

A random sample of 12 chemists from Washington stats shows an average salary of $39,420 with a standard deviation of $1659. A random sample of 26 chemists from New Mexico has an average salary of $30,215 with a standard deviation of $4116. Find the 98% confidence interval of the difference of means.

Answers

Answer:

Step-by-step explanation:

Given that :

μ1 = 39420 ; σ1 = 1659 ; s1 = 12

μ2 = 30215 ; σ2 = 4116 ; s2 = 26

df1 = 12 - 1 = 11

df2 = 26 - 1 = 25

98 % confidence interval of the difference in sample means :

Pooled Variance :

S²p = ((df1 * s1²) + (df2 * s2²)) / (df1 + df2)

((11×1659^2)+(25×4116^2))÷(11+25) = 12605874.75

Standard Error :

√(S²p/n1) + (S²p/n2)

√(12605874.75/12) + (12605874.75/26)

= 1239.0847
