expressions that are equivalent to 3^8 x 27

Let, after h hours both would charge the same amount.

Money charged by Alexa in h hours :

A = 40 + 10h    .... 1)

Money charged by Nick in h hours :

N = 0 + 50h      .... 2)

For equal charge :

A = N

40 + 10h = 50h

40h = 40

h = 1 hour

Therefore, Alexa and Nick would charge the same amount at first hour.

Hence, this is the required solution.

Answer:

23/3 OR 7 and 2/3

Answer:

[tex](-\frac{2}{7},-\frac{65}{7} )[/tex]

Step-by-step explanation:

By steps in the image:

Step 1:

To eliminate, you need one of the coefficients to be the same in both equations. We will use the term "-6x" found in the first equation.

To get this, multiply the entire second equation by 6 and simplify using the distributive property. The new equation is:

[tex]6x-6y=54[/tex]

Step 2:

Now you need to subtract the first equation and the new version of the second equation. By doing this, the "-6x" in both equations will cancel each other out.

Step 3:

Solve for x in the given equation by:

Step 4:

Solve for y by:

Solution:

[tex](-\frac{2}{7},-\frac{65}{7} )[/tex]

Answer:

false the |-| mean the absolute value thus it would = the same

Answer: False

Step-by-step explanation:

This is absolute value. The absolute value of -3 is 3 because lets say you have a number line, how far is -3 to 0 ? Its 3 . Your answer would be that its equal.

Answer:

-35, -33, -31

Step-by-step explanation:

Let the 3 consecutive odd integers be x+1,x+3,x+5

Given, x+1+x+3+x+5=-99

3x+9=-99

3x=-108

x=-36

The 3 odd integers are x+1 = -35, x+3=-33, x+5=-31

Well is it 8  3/4? Because i got no idea

Answer:

8 3/4

Step-by-step explanation:

The reason is because on the graph the most common size was 1 3/4, so you count how many x's there was. There were 5 x's so you multiply 1 3/4 by 5 and you get 8 3/4

Answer:

Addition Property

Step-by-step explanation:

Because since there are the plus sign there is no x - or a ÷sign so its Addition Property

13 + 7 = 20 ⇒ 13 + 7 +2 = 20 + 2 represents addition property of equality.

" Equality means representation of any two quantities using mathematical expression with the sign of 'equals to'."

According to the question,

Given,

13 + 7 = 20

Add '2' both the side  of the given equality we get,

⇒ 13 + 7 + 2 = 20 + 2

Add both the sides represents  addition property of equality.

Hence, Option(D) is the correct answer.

Answer:

Step-by-step explanation:

Answer:

b

Step-by-step explanation:

The test had '10' 4-point questions and '30' 3-point questions in the math test.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Sophia’s math test is worth 130 points and has 40 problems.

And, Each problem is worth either 4 points or 3 points.

Now,

Let number of 4 point questions = x

And, Number of 3 point questions = y

Since, There are 40 problems.

So, We get;

x + y = 40   .... (i)

And, Each problem is worth either 4 points or 3 points.

So, We can formulate;

4x + 3y = 130   .... (ii)

Solve equation (i) and (ii) as;

Multiply by 4 in equation (i), we get;

4x + 4y = 160

Subtract from equation (ii),

y = 30

And, x + y = 40

x = 40 - 30

x = 10

Thus, The test had '10' 4-point questions and '30' 3-point questions in the math test.

Answer:

13,500,000,000

Answer:

13500000000

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given the equation of the lines expressed as:

L1: y = 2/3 x - 3 and L2: y = -3/2 x +2

Comparing to the standard form of equation of a line y= mx+c

The slope of L1 is m1 = 2/3

The slope of line L2 is -3/2

Since their slope are not the same, therefore the lines are not parallel to each other.

For two lines to be perpendicular, the product of their slope is -1.

Let's check for both lines:

Check the product of their slope;

m1m2 =2/3 * -3/2

m1m2 = -6/6

m1m12 = -1

Since the product of their slope is -1, hence the lines are perpendicular to each other.

t=9.48n+119.88

Step-by-step explanation:

where t is the total cost of 12 t-shirts, and n is the number of words in the design

0.75n+9.99 is the equation for custom made t-shirts, and n represents the number of words in the design

t=12(0.75n+9.99)

where t is the total cost of t-shirts, and n is the number of words in the design

When simplified, this becomes t=9.48n+119.88
