Answer:

23/100

Step-by-step explanation:

Given the decimal value 0.23, to write as a fraction;

0.23 = 23/100

The place value of dot will be replaced as 1 at the denominator and since the decimal is in 2 decimal places, two zeros will be added to after the 1 to make it 10 thereby making the required fraction 23/100.  Hence the value of 0.23 as a fraction will be 23/100

Answer:

g(x) = |x + 4| - 2

I recommend next time you try substituting the x-values from points the line meets into each function until g(x) matches the y-value. For example, the line/function passes through the point (1, 3).  Substitute the x-value: 1 into the function where it says x. That would give you 3 = |1 + 4| - 2. (If you're wondering where I got 3 from g(x) is basically the same as y. Simplify the values in the "||" first. You should then get 3 = 5 - 2. Simplify that and you get 3 = 3 which means g(x) = |x + 4| - 2 is the correct answer. If you were to get anything else other than 3 such as "3 = 4", it would not be correct.

Answer:the fourth number is =97

Step-by-step explanation:

Mean = total number of the given numbers( x1 +x2+ x3....) /  numbers given

Let the fourth number be x

given that the mean of 4 numbers = 88 and only 3 numbers are given

such that

Mean = total number of the given numbers( x1 +x2+ x3....) /  numbers given becomes

88=  (80 +90 + 85 + x ) / 4

88 x 4 =80 +90 + 85 + x

352=255+x

x= 352-255

x=97

Answer:

algebraically.

y = 2x - 4........….....(1)

x + 2y = 12..............(2)

substituting the value of y in equation (2) we get

x+2(2x - 4)=12

x+4x-8=12

5x=12+8

x=20/5=4

substituting the value of x in equation(1) we get

y=2×4-4=8-4=4

:.(x,y)=(4,4)answer

The value of x = 4

The value of y = 4

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be = A

Let the second equation be = B

Now ,

y = 2x -4

Subtracting 2x on both sides , we get

y - 2x = -4   be equation (1)

And ,

x + 2y = 12   be equation (2)

Now , on simplifying the two equations , we get

Multiply equation (1) by 2 , we get

2y - 4x = -8   be equation (3)

Now , subtract equation (3) from equation (2) , we get

5x = 20

Divide by 5 on both sides , we get

x = 4

Therefore , the value of x is 4

Substitute the value of x in equation (2) , we get

4 + 2y = 12

Subtracting 4 on both sides , we get

2y = 8

Divide by 2 on both sides , we get

y = 4

Therefore , the value of y is 4

Hence , The value of x and y is 4

Answer:

Step-by-step explanation:

Answer:

4x= 40

Step-by-step explanation:

40/4 = 10

Answer:

21°

Step-by-step explanation:

<DCB = 3x + 8°

< DAB = 5x + 4°

Now

<DCB + <DAB = 180° { being opposite angles of cyclic quadrilateral }

3x + 8° + 5x + 4° = 180°

8x + 12° = 180°

8x = 180° - 12°

8x = 168°

x = 168° / 8

Therefore x = 21°

Step-by-step explanation:

Answer:

A:(1,-3/4)

Step-by-step explanation:

Use substitution to solve the system

y= 1/4x-1

y= -1/2x-1/4

1/4x-1 = -1/2x-1/4, Solve for x

3/4x= 3/4, x = 1, Next solve for y by plugging the x-value into either equation.

y=1/4(1)-1

y=-3/4

Answer:

If your trying to answer for X, here is how you do it.

For the equation '' Y = 10x + 20 '', isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:

X =  Y/10 − 2

Or

X = [tex]\frac{Y}{10}[/tex] − 2

For the other equation " Y = 20x + 10 ", it's the exact same thing. Isolate the variable 'X' by dividing each side by factors that don't contain the variable 'X', to get your answer:

X = Y/20 − 1/2

Or

X = [tex]\frac{Y}{20}[/tex] − [tex]\frac{1}{2}[/tex]

Answer:

First of all, a quotient is a number that the answer to a division number basically. So, I think the best answer would be the first choice: 4 times 10 with an exponent of 12. I think that is the correct answer.

Answer:

I think that it would be true.

Step-by-step explanation:

I think it's true, because it has the union of three or more line segments whose endpoints meet.

Answer: £180

Step-by-step explanation:

The interest gotten for the 10 years will be calculated as:

= Principal × Rate × Time

= 150 × 2% × 10

= 150 × 0.02 × 10

= 30

The amount he has in the bank account at the end of the 10 year will be:

= Principal + Interest

= £150 + £30

= £180

Answer: 12%

Step-by-step explanation:

Answer:

3.2 x 10^5 goes in greater than 2.4 x 10^4

1.9 x 10^-1 goes in less than 1.2 x 10^2

2.2 x 10 goes in less than 1.2 x 10^2

2.4 x 10^3 goes in between 1.2 x 10^2 and 2.4 x 10^4

5.9 x 10^2 goes in between 1.2 x 10^2 and 2.4 x 10^4

6.1 x 10 goes in less than 1.2 x 10^2

2.5 x 10^4 goes in greater than 2.4 x 10^4

Step-by-step explanation:

First let's find out what 2.4 x 10^4 and 1.2 x 10^2 is.

2.4 x 10^4 = 24000

1.2 x 10^2 = 120

3.2 x 10^5 is obviously greater than 2.4 x 10^4 because the exponent of ten in 3.2 x 10^5 is one more value than the exponent in 2.4 x 10^4. The decimal is also greater.

1.9 x 10^-1 = .19, which is less than 1.2 x 10^2

2.2 x 10 = 22, less than 1.2 x 10^2

2.4 x 10^3 = 2400, in between 1.2 x 10^2 and 2.4 x 10^4

5.9 x 10^2 = 590, in between 1.2 x 10^2 and 2.4 x 10^4

6.1 x 10 = 61, less than 1.2 x 10^2

2.5 x 10^4 we can solve without doing the math, 2.5 is greater than 2.4 meaning the product will be greater, to check I did the math 2.5 x 10^4 = 25000, greater than 2.4 x 10^4
