ratelena [41]3 years ago
4 0

Answer:

The value of 11+x at x=12 will be 23.

Step-by-step explanation:

Given the expression

  • 11 + x

As we have to evaluate the expression at x=12

so substitute the value x=12 in the expression

11 + x

=11+12

=23

Therefore, the value of 11+x at x=12 will be 23.

M( -6, 4) is the midpoint of RS. If S has coordinates (-3, 10), find the coordinates of R.
poizon [28]

Answer:

Coordinate of R is (-9, -2)

Step-by-step explanation:

Given

M (-6, 4)

S (-3, 10)

Distance between M and S are x = 3  y = 6

Since M is the midpoint between RS, such that distance between RM = MS

x = -6 - 3 = - 9

y = 4 - 6 = - 2

Find the measure of angle x. Round your answer to the nearest hundredth. (please type the numerical answer only)
denis23 [38]

The measure of the angle x to the nearest hundredth is  22.62 degrees.

<h3>How to find the measure of an angle in a right triangle?</h3>

A right triangle is a triangle that has one of its angles as 90 degrees.

Therefore, the sides or angles can be found using trigonometric ratios, depending on the parameters given.

Hence, using trigonometric ratios,

cos x° = adjacent / hypotenuse

Therefore,

hypotenuse = 13 units

adjacent side = 12 units

Thus,

cos x = 12 / 13

cos x = 0.92307692307

x = cos ⁻¹ 0.92307692307

x = cos¹ 0.92307692307

x  = 22.619864948

x = 22.62 degrees

Therefore, the measure of the angle x to the nearest hundredth is  22.62 degrees.

2(3x+2)=2x+28<br><br> What is x?
kherson [118]

Answer:

x = 6

Step-by-step explanation:

<u>Step 1:  Distribute </u>

2(3x + 2) = 2x + 28

(2 * 3x) + (2 * 2) = 2x + 28

(6x) + (4) = 2x + 28

<u>Step 2:  Subtract 2x from both sides </u>

6x + 4 - 2x = 2x + 28 - 2x

4x + 4 = 28

<u>Step 3:  Subtract 4 from both sides </u>

4x + 4 - 4 = 28 - 4

4x = 24

<u>Step 4:  Divide both sides by 4 </u>

4x / 4 = 24 / 4

<em>x = 6 </em>

Answer:  x = 6
