solve For X if 9( x²_1 )= 27 x 2187​

Answer:

7/2 = 35/10

3/5 = 6/10

Step-by-step explanation:

To get a common denominator of 10, simply multiply the current denominator by any number to equal 10. The first fraction has a denominator of 2. If we divide 10 by 2, we get the answer 5. This means 2 can be multiplied by 5 to get a denominator of 10. However, what we do to the denominator we must also do to the numerator (multiply by 5).

7/2

7 × 5 / 2 × 5

35/10

3/5

3 × 2 / 5 × 2

6/10

Answer:

7/2 = 35/10

3/5 = 6/10

Step-by-step explanation:

Answer:

The equation of the line is x = 2

Answer:

x = 2

Step-by-step explanation:

When you are given a straight line whether it's horizontal or vertical on a graph and is told to write it as an equation,

it can be a horizontal line, y = the number the line is on from the y-axis

or a vertical line, x = the number the line is on from the x-axis.

In this case you have a vertical line so the equation would be

x = the number the line is on from the x-axis, which is 2 so your final answer would be

x = 2

Answer: 61 cents

Step-by-step explanation:

Let’s assume a circle is X and a square is Y.

The problem states:

5x + 1y = 20

2x + 3y = 21

Taking the 1st equation we can see that

1y = 20-5x which is the same as

y = 20–5x

If we replace y in the 2nd equation with the above we get:

2x + 3(20–5x) = 21

which is the same as

2x + 60 - 15x = 21

we can rearrange to get

2x -15x = 21 -60

which is the same as:

-13x = -39

therefore x = -39/-13 or

x = 3

We can then calculate y

If y = 20–5x, then y = 20 -15

There y = 5

So to answer you question, 12 circles plus 5 squares =

12x + 5y = 12(3) + 5(5) = 36 + 25 = 61 cents

Answer:

The 2 numbers are 32 and 27.

Step-by-step explanation:

32 plus 27 equals 59.

32 minus 27 equals 3.

Answer:

x=16 would be the angle measures.

Answer:

15: Yes, no, yes, yes, no; 16A: C = ($0.29)X + ($1.45)Y + ($2.50)Z; 16B: Yes

Step-by-step explanation:

For question 15: We need to multiply the widths and lengths given to see if they equal the area we are trying to achieve. Therefore, some of them work, and some do not.

For question 16:

Part A: We'll set a variable for the number of each supply she can buy. Pencils will be represented by X, pens by Y and Notebooks by Z, and we'll represent total cost by C. The total cost will therefore be represented by C = ($0.29)X + ($1.45)Y + ($2.50)Z.

Part B: We'll plug the numbers of items she wants to buy into our formula and see if it comes out to less than $20. So in this case C = ($0.29)(3) + ($1.45)(4) + ($2.50)(2). Therefore, C = $11.67, which is less than $20, so she can afford her school supplies.

Answer:

A function is a rule that assigns to each input exactly one output.

Step-by-step explanation:

If you have more than one of the same inputs for multiple outputs, it would create a vertical line at somepoint on your line.

Answer:

The correct answer is "a rule that assigns to each input exactly one output".

Step-by-step explanation:

In mathematics, a function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. Typical examples are functions from integers to integers, or from real numbers to real numbers.

Answer:

a) 30% probability that it will not be colder today than it was yesterday

b) 90% probability that it will not be warmer today than it was yesterday

Step-by-step explanation:

In this question, we have that:

0.1 = 10% probability it will be warmer today than yesterday.

0.7 = 70% probability it will be colder today than yesterday.

a .What is the probability that it will not be colder today than it was yesterday?

70% probability it will be colder, so 100 - 70 = 30% probability that it will not be colder today than it was yesterday.

b What is the probability that it will not be warmer today than it was yesterday?

10% probability it will be warmer today than yesterday, so 100 - 10 = 90% probability that it will not be warmer today than it was yesterday

Answer:

X=3

Step-by-step explanation:

Since all the sides of a square are equal, hence;

5x-2 = x+10

Collect like terms

5x-x = 10+2

4x =12

X = 12/4

X =3

Hence the value of x is 3

Answer:

25

Step-by-step explanation:

All the data values from least to greatest:

20, 23, 23, 25, 25, 27, 27, 27, 28

Since the data values are odd, the middle value is the median:

25

Answer:

- 1

Step-by-step explanation:

( x + 4 )² + 38 = 47

( x + 4 )² = 47 - 38

( x + 4 )² = 9

( x + 4 )² = 3²

Square root on both sides,

x + 4 = 3

x = 3 - 4

x = - 1

From what i understand from the picture is there is a right angle triangle given with the hypotenes being 37, base being 12 and the perpendicular is 35.

we need to determine the value or Cos x

Easy way to remember which value to out where is

sinx=p/h -----> some people have

cosx=b/h ----> curly brown hair

tanx=p/b -----> through proper brushing

learned this is 8th grade in collage right now still comes in handy

we need cosx so we will use the second formula

[tex]cosx=\frac{b}{h} \\\cosx=\frac{12}{37} \\x= cosx^{-1} (\frac{12}{37})\\[/tex]

which can then be simplified using a calculator

x= 71.1 degree

for this question from what i understand is the answer is cos x = cos (12/37)
