4 • 23 = 92 so the correct answer is a  4(20+3).

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

For example, x + y is an expression, where x and y are terms having an addition operator in between.

Expressions can be simplified to form an answer. For example, 3+6-2 is an expression that can be simplified to 7. There are two different ways to simplify arithmetic expressions and algebraic expressions. We use the bracket open division multiplication addition subtraction rule which means the operations are performed in the given manner to simplify them.

For example, 2x+5x results in 7x, whereas 7ab-b is an expression that has two unlike terms, which cannot be added.

Checking for all the options:

option a) 4 (20+3)=4 * 23 = 92

option b) 4 (2 + 13) = 4 * 15 =60

option c) 4 (20 + 30) = 4 * 50 =200

option d) 4 (2 + 3) = 4 * 5 = 20

None of the above, since the improper fraction 4/3 is identical to the mixed number 1 1/3.

There are various types of fractions, including proper and improper fractions as well as mixed numbers. Mixed numbers: Sometimes converting a mixed number into an incorrect fraction is advantageous or required. If you answer equations that contain both mixed numbers and fractions, you must take this step.

Divide the full integer by the denominator of the fraction (3). (1). 3 x 1 = 3. The product you obtained in the previous step (3) after adding the fraction's numerator (1) is equal to four. 1 + 3 = 4.This turns becomes the improper fraction's numerator. As with the proportion in the mixed number, the denominator remains constant.

Hence, the set of numbers 1 1/3 fraction is 4/3.

The equation of the linear function represented by the table below in slope-intercept form is y = 5x + 4

The equation of a line in point-slope form is expressed as y = mx + b

where

m is the slope

b is the intercept

Using the coordinate points (-1,-1) and (2, 14)

Slope = 14+1/2+1

slope = 15/3

Slope = 5

For the intercept;

14 = 5(2) + b

14 = 10 + b

b = 4

The y-intercept is at the point (0,4)

Determine the equation

y = mx + b

y = 5x + 4

Hence the equation of the linear function represented by the table below in slope-intercept form is y = 5x + 4

Caroline's age is 21 years which is an odd integer.

Integers are a subset of real numbers.

It is given that Caroline is the youngest of 4 siblings and all of their ages are odd consecutive integers.

Let us consider the age of Caroline's age to be x years(x is an odd integer).

She is the youngest so the sibling's age who is just older than Caroline is given by x+2 which is also another odd integer.

Ages of the other two siblings will be x + 4 , x + 6 .

Now sum of their ages is 96.

Therefore: x + (x+2) + (x+4) + (x+6) =96

or, 4x + 12 = 96

or, 4x = 84

or, x = 21 (odd integer)

Answer:

The person runs 30km/h or 30000m/h

Step-by-step explanation:

First let's find speed per minute

➟ 1500/3

➟ 500

Now let's calculate speed per hour

1 hour = 60 minutes

➟ 500 × 60

➟ 30,000 meters

If you would like the meters to be in miles

then Formula divide the meter value by 1000

➟ 30000/1000

➟30

∴ The person runs 30km/h or 30000m/h

The speed of the person is 300 km/hour.

Speed is the ratio of distance and time.

It shows how fast an object is moving at a given time.

We have,

Distance covered in 3 minutes = 1500 meters.

1 hour = 60 minutes

3 minutes = 15000 meter

Multiply 20 on both sides.

60 minutes = 300,000 meter

1 km = 1000 meter

Multiply 300 on both sides.

300 km = 300,000 meter

Now,

60 minutes = 300 km

Speed = 300 km/hour

Thus,

300km/hour is the speed of the person.

The perimeter of the quadrilateral is approximately 50.47 units

Given the vertices of the quadrilateral: H(– 4,6), I(4,9), J(2,3), K(7, – 4).

Let us calculate the distances of HI , IJ , JK and KH

[tex]{\displaystyle HI={\sqrt {(4-(-4))^{2}+(9-(6))^{2}}}.}[/tex]

or, HI = 17 units

[tex]{\displaystyle IJ={\sqrt {(2-(4))^{2}+(3-(9))^{2}}}.}[/tex]

or, IJ = 10

[tex]{\displaystyle JK={\sqrt {(7-(2))^{2}+(-4-(3))^{2}}}.}[/tex]

or, JK = √74 = 8.602... ≈ 8.60

[tex]{\displaystyle KH={\sqrt {(7-(-4))^{2}+(-4-(6))^{2}}}.}[/tex]

or, KH = √221 = 14.866... ≈ 14.87

Now perimeter = HI + IJ + JK + KH

Answer:the answer is A:nick is correct

Step-by-step explanation:

Based on the fraction given of [tex]\large \frac{2\cdot3^{-4}}{5^{-2}}[/tex], the correct person is c. Nick is correct because the negative exponent in the numerator moves the whole numerator into the denominator and makes the exponent positive.

When a number is being taken to the negative power, then it can be rewritten as a fraction where the number becomes the denominator and the numerator becomes 1.

The number, 2.3⁻⁴ can be written as:

= 1/2.3⁴

The number 5⁻² can be written as:

= 1 / 5²

When these numbers are divided we get:

= 1/2.3⁴ ÷ 1 / 5²

= 1/2.3⁴ x 5²/1

= 5² / 2.3⁴

= [tex]\large \frac{5^2}{2\cdot3^4}[/tex]

The original price of a zip disk is; $1.4

Let cost of zip sticks bought by Ramon be x. Thus;

Cost that Ramon paid = 5x

Now, we are told that 2 days later the price increased by $1.5 per disc. Thus, new cost = x + 1.5

Leticia bought ten disks at the sale price and paid 22 more than ramon paid for 5 disks. Thus, equation here is;

10(x + 1.5) = 5x + 22

Expand the bracket to get;

10x + 15 = 5x + 22

10x - 5x = 22 - 15
