Step-by-step explanation:

2x+4=x+18

2x-x=18-4( Addition on the Right hand side changes to subtraction on the left hand side and wise-versa.)

1x=14

1x(1*x so X itself)

X=14

Answer:

x+2x+4_x_18=0

2x_14=0

x=14÷2

x=7

Answer:

x = 3.5

Step-by-step explanation:

diagonals bisect each other so AW = OW

since AO = 22 then AW = 11

11 = 4x - 3

14 = 4x

x = 7/2 or 3 1/2

Answer:

x=25+30=55 since the vertically opposite angle are equal.sorry the no is not clear in question

Answer:

[tex]\boxed{\tt x= 45^{\circ}}[/tex]

Step-by-step explanation:

∠BEG and ∠DEB combine to form ⇒ ∠DEG, which is a vertical angle with ∠x because it's the opposite from ∠x.

(Vertical angles are always congruent, or of equal measure)

So, [tex]\tt \angle BEG +\angle DEB=\angle x[/tex]

[tex]\tt \angle BEG +\angle DEB=\angle x[/tex]

[tex]\tt 25^{\circ}+20=x[/tex]

[tex]\tt 45^{\circ}=x[/tex]

[tex]\tt x= 45^{\circ}[/tex]

Answer:

11

Step-by-step explanation:

A prime number is a number that cannot be factored other than 1 and that number is self thus, 11 will be the prime number.

The number system is a way to represent or express numbers.

A decimal number is a very common number that we use frequently.

Since the decimal number system employs ten digits from 0 to 9, it has a base of 10.

A prime number is a number that cannot be factored other than 1 and that number is self.

For example, 9 can be written as 3 x 3 thus it will not prime number and 11 cannot be written as two products other than 1 x 11 thus it will be a prime number.

Hence "A prime number is a number that cannot be factored other than 1 and that number is self thus, 11 will be the prime number".

From the central limit theorem, the interval can the researcher be 95% certain that the sample mean will fall within A. $257.82 and $272.18.

How to use the Central limit theorem?

We are given;

Population Mean; μ = $265

Population standard deviation; σ = $40.93

Sample size; n = 130

The central limit theorem (CLT) postulates that the distribution of sample mean approximates a normal distribution with larger sample sizes, disregarding the population's distribution.

This implies that sample sizes equal to or greater than 30 are often considered sufficient for the Central limit theorem to hold.

Thus, by the central limit theorem, the interval can the researcher be 95% certain that the sample mean will fall within A. $257.82 and $272.18.

Answer:

Step-by-step explanation:

V=hb/3, where b=area of base

b=3V/h, since V=30mm^3 and h=5mm then

b=3(30)/5

b=18 mm^2

So the area of the base is 18 square millimeters.
