Answer:

<h2>x = 5</h2>

Step-by-step explanation:

In algebra, the goal is always to isolate the variable, so that its value can be determined.

<h3>Step 1: Use Distributive Property</h3>

2x + 22 = 4x + 12

<h3>Step 2: Subtract 4x</h3>

-2x + 22 = 12

<h3>Step 3: Subtract 22</h3>

-2x = -10

<h3>Step 4: Divide by -2</h3>

x = 5

<h3>Step 5: Check</h3>

2(5) + 22 = 4(5) + 12

10 + 22 = 20 + 12

32 = 32 ✔

<h3>Step 6: Answer </h3>

x = 5

I'm always happy to help :)

MAVERICK [17]

Answer:

1. The correct options are 2 and 4.

2. The measure of angle 6 is 60°.

Step-by-step explanation:

1.

It is given that a∥b , and c is not parallel to a or b. So, we can not establish any relationship among the angles on the line a,b and  angles on the line c.

If a traversal line intersect two parallel line, then corresponding angles, alternate exterior angle and alternate interior angles are equal.

\angle 2=\angle 6=\angle 3=\angle 7

\angle 1=\angle 5=\angle 4=\angle 8

Therefore  correct options are 2 and 4.

2.

It is given that AB∥CD and m∠3=120°.

Statements                     Reasons

​ m∥nm∠1=120° ​                Given

∠5≅∠1                             Corresponding angles are equal

m∠5=m∠1                    Angle Congruence Postulate

m∠5=120°                    Substitution Property of Equality

m∠6+m∠5=180°             Supplementary angle property

m∠6+120°=180°            Substitution Property of Equality

m∠6=60° ​                    Subtraction Property of Equality

Therefore the measure of angle 6 is 60°.

Last year for 6 consecutive months, Sam recorded the total number of miles for each month. These miles were: 1,086, 997, 1,534,
IceJOKER [234]

Answer:

The median number of miles that Sam drove during those months is 1044 miles

Step-by-step explanation:

The median separates the upper half from the lower half of a set. So 50% of the values in a data set lie at or below the median, and 50% lie at or above the median.

For a set of n values

First we order the values in an increasing way.

If n is odd, the median is the value at the position (n+1)/2

If n is even, the median is the average of the values at the positions n/2 and (n/2) + 1

In this problem:

6 values

Ordered in an increasing way:

880, 997, 1002, 1086, 1534, 1637

6 is an even value.

6/2 = 3. The third element is 1002

6/2 + 1 = 4. The fourth element is 1086.

Average: (1002 + 1086)/2 = 1044

The median number of miles that Sam drove during those months is 1044 miles

Whst is the remainder when f(x)=x^3+3x^2-10x-4 is diveded by x-3
Vesnalui [34]
The polynomial remainder theorem allows us to calculate the remainder when a polynomial is divided by a linear polynomial:
The remainder of f(x) divided by (x-k) equals f(k).

Thus
f(x)=x^3+3x^2-10x-4 divided by x-3
gives a remainder of
f(3)=27+3(9)-10(3)-4=27+27-30-4=20
Therefore the remainder required is 20.
