Answer:

14 is to the right of -23

Step-by-step explanation:

On the number line, the number 14 will appear on the right side of -23 with respect to zero from front.

Integers are arranged at equal intervals along horizontal straight lines called number lines. A number line can be used to represent every number in a series.

Number line is a graphical representation of whole numbers, natural numbers, rational and irrational numbers. which represents both negative and positive numbers such that, positive numbers from 1 to infinity lie on the right-hand side of zero and negative numbers from (- 1) to (- infinity) lie on the left-hand side of zero.

Therefore, zero is considered as the reference point.

Number 14 is positive natural number, it appears on the right side of zero and (-23) appears on the left side of zero.

Thus, On a number line, the number 14 lies to the right of number -23.

The value of x when f(x) = 1 is  x = 2.

A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

Given:

The function,

f(x) = 3x – 5.

Solving for x when f(x) = 1,

1 = 3x - 5

3x = 6

x = 2

Therefore, the value is x = 2.

Answer:

431.25 approximately 431

Step-by-step explanation:

one way of calculating it would be to get the measure per one person which would be equal to 46 / 64 = 0.7 people in one square feet

then multiply 0.7 by the total distance = 431.25 approximated to 431

Answer:

−3b /8

​  

Step-by-step explanation:

Answer:

b + 11 = 11 + b

Step-by-step explanation:

Combine like terms. Note that because you are adding for all terms, you can technically disregard the parenthesis:

3 + (b + 8) = b + 3 + 8 = b + 11

3 + (8 + b) = 3 + 8 + b = 11 + b

b + 11 = 11 + b (True).

In this problem, we'll need to divide the number of apples by the amount of apples in a small bag. This will leave us with the number of small bags needed for the amount of apples.

91 / 7 = 13

Therefore, Alexa and her family bought 13 small bags of apples.

Answer:

1/2

Step-by-step explanation:

First, I added the two numbers tat we had already.

Step-by-step explanation:

His initial cost of the phone bill was  $25.90, which is the constant. He is charge $0.18 for each text. So you will have to add the initial bill and costs of the texts to get final cost on the phone bill, which is $30.40.

Answer:

Number of way s= N=100

The probability that it passes through  first of four servers at the third step is 0.25

Step-by-step explanation:

The total number of possible ways can be found out by multiplying the possibilities so the possibilities at the

1st stage is  5

2nd stage is 5

3rd stage is  4

4th stage is 1

So Number of way s= N= 5*5*4= 100

This can be solved by drawing a tree diagram as well.

Now the probability of finding the  that a message passes through the first of four servers at the third step.

There are five paths

And we have to find the probability of four

So 5C1*5C4/100= 0.25

The probability that it passes through  first of four servers at the third step is 0.25

[tex]2\frac{1}{3}[/tex] is a mixed fraction and 7/3 is a improper fraction.

A fraction represents a part of a whole.

We need to write a improper fraction and a mixed number for the shaded portion of the group of figures

Fractions are three types proper, improper and mixed fraction

A proper fraction is a fraction which has its numerator value less than the denominator.

A improper fraction is a fraction which has its numerator value greater than the denominator.

A fraction represented with its quotient and remainder is a mixed fraction.

[tex]2\frac{1}{3}[/tex] is a mixed fraction

7/3 is a improper fraction.

Hence, [tex]2\frac{1}{3}[/tex] is a mixed fraction and 7/3 is a improper fraction.

Answer:

8695

Step-by-step explanation:

Took forever on calculator but I did it!

Answer:

8695

Step-by-step explanation:

There is a formula for adding all integers from 1 to some integer n.

[tex] 1 + 2 + 3 + ... + n = \dfrac{n(n + 1)}{2} [/tex]

In other words, to add all integers from 1 to an integer, multiply the integer by the next greater integer and divide by 2.

For example, what is

1 + 2 + 3 + 4 ?

Multiply 4 by the next integer, 5, and divide by 2.

(4 * 5)/2 = 20/2 = 10

Check: 1 + 2 + 3 + 4 = 3 + 3 + 4 = 6 + 4 = 10

We see that the formula works.

Now we need to apply that formula to this problem, but there's a little more to it.

If the problem were

1 + 2 + 3 + ... + 138 + 139, then we'd apply the formula and that would be it.

In this problem, though, we don't start the sum at 1. We start the sum at 46.

The trick here is to add all integers from 1 to 139, and then we subtract the sum of all integers from 1 to 45, so we are left with only the sum of the integers from 46 to 139.

Sum of integers from 1 to 139:

[tex] 1 + 2 + 3 + ... + 139 = \dfrac{139(139 + 1)}{2} = \dfrac{139(140)}{2} = 9730 [/tex]

Sum of integers from 1 to 45:

[tex] 1 + 2 + 3 + ... + 45 = \dfrac{45(45 + 1)}{2} = \dfrac{45(46)}{2} = 1035 [/tex]

Now we subtract the sum to 45 from the sum to 139.

46 + 47 + 48 + ... 138 + 139 = 9730 - 1035 = 8695

Answer: B) Profit per shirt goes from $10 to $15

================================================

Explanation:

Focus on the two points (2,0) and (3,10). The slope of the line through these points is

m = (y2-y1)/(x2-x1)

m = (10-0)/(3-2)

m = 10

Meaning the profit per shirt for this line is $10 per shirt.

----------

Now move onto the other line. Focus on the points (9,40) and (11,70)

m = (y2-y1)/(x2-x1)

m = (70-40)/(11-9)

m = 15

The profit per shirt has gone up to $15 per shirt

Answer:

Answer:

2 (5 x - 2) = 10 x - 4 or x = 2/5 (if you need to solve for x)

Step-by-step explanation:

Simplify the following:

4 x - 2 + 6 x - 2

Hint: | Group like terms in 4 x - 2 + 6 x - 2.

Grouping like terms, 4 x - 2 + 6 x - 2 = (4 x + 6 x) + (-2 - 2):

(4 x + 6 x) + (-2 - 2)

Hint: | Add like terms in 4 x + 6 x.

4 x + 6 x = 10 x:

10 x + (-2 - 2)

Hint: | Group the negative terms in -2 - 2 together and factor out the minus sign.

-2 - 2 = -(2 + 2):

10 x + -(2 + 2)

Hint: | Evaluate 2 + 2.

2 + 2 = 4:

10 x - 4

Hint: | Factor out the greatest common divisor of the coefficients of 10 x - 4.

Factor 2 out of 10 x - 4:

Answer: 2 (5 x - 2)

________________________________

if you need to solve for x then:

Solve for x:

10 x - 4 = 0

Add 4 to both sides:

10 x + (4 - 4) = 4

4 - 4 = 0:

10 x = 4

Divide both sides of 10 x = 4 by 10:

(10 x)/10 = 4/10

10/10 = 1:

x = 4/10

The gcd of 4 and 10 is 2, so 4/10 = (2×2)/(2×5) = 2/2×2/5 = 2/5:

Answer:  x = 2/5

==================================================

Explanation:

Multiply top and bottom of the original fraction by 2

[tex]\frac{5}{16} = \frac{5*2}{16*2} = \frac{10}{32}[/tex]

Or you could go in reverse to divide each part of 10/32 by the GCF 2

[tex]\frac{10}{32} = \frac{10\div 2}{32\div 2} = \frac{5}{16}[/tex]

-------------------

Another alternative is to use your calculator to find the decimal version of each answer choice

5/32 = 0.15625

10/32 = 0.3125

1/2 = 0.5

10/16 = 0.625

And compare these results with 5/16 = 0.3125

Both 5/16 and 10/32 have the same decimal value 0.3125, which makes them equal.

Answer:

x = -3/2

Step-by-step explanation:

Let's solve your equation step-by-step.

4(x+2(3x−7))=22x−65

Step 1: Simplify both sides of the equation.

4(x+2(3x−7))=22x−65

(4)(x)+(4)(2(3x−7))=22x+−65(Distribute)

4x+24x+−56=22x+−65

(4x+24x)+(−56)=22x−65(Combine Like Terms)

28x+−56=22x−65

28x−56=22x−65

Step 2: Subtract 22x from both sides.

28x−56−22x=22x−65−22x

6x−56=−65

Step 3: Add 56 to both sides.

6x−56+56=−65+56

6x=−9

Step 4: Divide both sides by 6.

6x = -9
