What’s meaning of x in math

Answers

Answer 1

Answer:

variable

The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

Answer:

50

Step-by-step explanation:

The way you solve this is by creating an inequality of

30          15

----     =   ----

100          x

So you cross multiply which would give you 30x = 1500, then you divide by 30 on both sides leaving you with 50. If you want to check it, you can then multiply 50 by .30 which would give you 15.

Okay so, to get C you add the ones inside the triangle together.

42+58=100 Then the last angle will be 80, because when you add the three inside the triangle, you should get 180

42+58+80=180

To get D, you have to subtract 180 and 58, because 58+d will be a straight angle.

180-58=121

To get B and A, you would also have another straight angle (c, b, and a)

180-80=100

I believe that B=A, so, with the remaining 100, both A and B equal 50.

50+50+80=180

Does this help??

Answer:

a° = 58°

b = 42°

c° = 80°

d° = 122°

Step-by-step explanation:

d° can be found because a straight line has an angle of 180°.

180° - 58° = 122°

Because the angles of a triangle add up to 180°, we can find c°

58° + 42° = 100°. 180° - 100° = 80°

You can find a° subtracting 180 and d°, which is 122. 180° - 122° = 58°

You can do the same thing for b°. 180° - 42° = 138°. 180° - 138° = 42°

You can check this because b° + c° + a° should equal 180°.

58° + 42° + 80° = 180°

Describe Maysa's error. Explain how you would use a model or place-value concepts to help Maysa build understanding. Give the correct answer in your explanation.

Answers

The correct answer for the given subtraction is:

3.5 - 2.46 = 1.04

How to solve the subtraction?

Here we want to find the subtraction between two numbers in decimal form:

3.5 - 2.46 = 1.16

Now, this is clearly wrong, as 0.46 is smaller than 0.5, so the decimals after the decimal point are incorrect, now let's solve it again.

First, we can rewrite these two numbers as:

3.5 = 3 + 0.5

2.46 = 2 + 0.46

Then the subtraction can be rewritten as:

3.5  - 2.46

(3 + 0.5) - (2 + 0.46)

Now we group like terms:

(3 - 2) + (0.5 - 0.46)

1 + (0.50 - 0.46)

1 + (0.04)

Now we group that, so we get:

1 + (0.04) = 1.04

This is the correct answer to the given subtraction.

0.1 m/s

0.1s

Answers

Answer:

Time, t = 9.615 secs.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex] ....equation 1

[tex]Time = \frac{distance}{speed}[/tex] .....equation 2

Given the following data;

Distance = 100m

Speed = 10.4m/s

Substituting into equation 2;

[tex]Time = \frac{100}{10.4}[/tex]

Time, t = 9.615 secs.

A students wants to help her mother in their family store in displaying canned goods. Her mother instructed that the canned should be piled in triangular pile by starting 40 canned goods in the bottom row, 36 in the second row, 32 in the third row, and so on. If the pattern is consistent, how many canned goods will be there in the 7th row?

Answers

Answer: The number of canned goods in 7th row = 64.

Step-by-step explanation:

The given numbers of canned goods in every row( starting from first ) is represented as

40 , 36, 32, ...

There is a common difference between numbers(d)= 4

∴ Its is an Arithmetic progression.

First term (a) = 40

nth term in A.P. : [tex]a(n)= a+(n-1)d[/tex]

7th term in this A.P. = 40+(7-1)(4)=40+(6)(4)=40+24=64

So, the number of canned goods in 7th row = 64.

you add up all of the numbers and you will get 35.

But, in this case, you need it to be a decimal so you just make it 0.35
