Answer:1.0

Step-by-step explanation: 0.999 repeating is not a whole number like 1.0

Answer:

1.0

Step-by-step explanation:

Look at where the numbers are placed, in regards to the decimal point.

If a number is 1 place before a decimal point (For example 5.0) it is in the ones place.

If a number is 1 place after a decimal point (For example 0.1) It is in the tenths place.

Any numbers that are to the right the decimal are smaller than numbers to the left!

Answer:

12.50x+30

Step-by-step explanation:

Answer:

[tex]y = 12.5x + 30[/tex]

Step-by-step explanation:

We are given the following information in the question:

Cost of a holiday meal = $12.50

Delivery fee = $30

Cost(y) represents the amount a holiday meal including delivery for x people.

[tex]cost = (\text{Cost of meal}\times x) + \text{Delivery chareges}[/tex]

Putting all the values,

[tex]y = 12.50\times x + 30\\y = 12.5x + 30[/tex]

The above equation gives the total amount of holiday meal for x people including the delivery charges.

Answer:

-4m-5

Step-by-step explanation:

The trick here is knowing not to combine terms with variables with terms that don't have variables.

[tex]m-7-(5m-2)\\m-7-5m+2\\m-5m-7+2\\-4m-5[/tex]

So the answer is -4m-5

Answer:

Step-by-step explanation:

[tex](m-7)-(5m-2)\\\\=m-7-5m-(-2)\\\\=m-7-5m+2\qquad\text{combine like terms}\\\\=(m-5m)+(-7+2)\\\\=-4m-5[/tex]

Answer: $251,535 is the total cost for all the laptops.

Step-by-step explanation:

615×409= 251,535

Answer:

[tex]total\ cost=\$251,535[/tex]

Step-by-step explanation:

For this exercise it is important to analize the information provided in the exercise.

According to the exercise, the of cost each computer is:

[tex]cost=\$409[/tex]

You know that the school district purchased 615 new laptops for their mobile labs; therefore, in order to calculate the total cost for all the laptops purchased, you must multiply the cost of one laptop ($409) by 615.

Therefore, you get that the total cost is the following:

[tex]total\ cost=(\$409)(615)\\\\total\ cost=\$251,535[/tex]

Step-by-step explanation:

The graph of y= -4×+7 is​ a straight line with slope -4 and y-intercept 7.  Please do not use × to represent the independent variable; use x instead.  × represents multiplication.

To graph this function, first plot the y-intercept, b, which is (0, 7).

Next, starting with your pencil point at (0, 7), move the point 1 unit to the right and plot another point (which will be (1, 7) ).  Now move your pencil point 4 units down and plot your third point, which will be (1, 3).

Finally, draw a straight line thru the first and third points, that is, thru (0, 7) and (1, 3).  Notice how this line has the slope -4 and the y-intercept (0, 7).

Answer:

b) 91

Step-by-step explanation:

Step 1: Multiple marks by its weights

Homework average: 95 x 20% = 19

Quiz average: 90 x 20% = 18

Test average: 87 x 40% = 34.8

Final exam: y x 20% = 0.2y

Step 2: Add all weighted averages and find y

19+18+34.8+0.2y = 90

71.8 + 0.2y = 90

y = 18.2/0.2

y = 91

Therefore, Anna needs to score minimum 91 in the final exam so that she can score a 90 in class.

Answer:

Step-by-step explanation:

We can multiply powers with the same base

x^4⋅x^2=(x⋅x⋅x⋅x)⋅(x⋅x)=x^6

Properties of exponents are rules used to simplify mathematical expressions involving exponents. Examples are Power of a Power which means adding exponents when multiplying two expressions with the same base, and Quotient of Powers which is subtracting exponents when dividing two expressions with the same base.

The question is about the properties of exponents. In mathematics, the properties of exponents refer to the rules that guide how expressions involving exponents are handled. For example, when you multiply two expressions with the same base, you add the exponents (also known as the Power of a Power property). So, an exponent like x^3 * x^2 simplifies to x^(3+2) = x^5.

Another example is the quotient of powers property, where you subtract the exponents when dividing two expressions with the same base. So, an expression like x^5 / x^3 simplifies to x^(5-3) = x^2.

These are just a couple of the basic properties of exponents. Other properties include the power of a product, the power of a quotient, zero exponent, and negative exponent. Each of these properties follows specific rules to simplify the expression involving exponents.

Answer:

18+t<26

t={1,2,3,4,5,6,7}

Step-by-step explanation:

18+t<26

alright, so you know that she will run less than 26. That means she cannot run 26 or 27 or any more miles than that.

She can run 19, 20, 21, 22, 23, 24, or 25 miles in total from her starting point which is 18.

She already ran 18 miles. If she ran one more it would be 19, if she ran 2 more it could be 20. But she CAN NOT pass 25 miles. (it is not less than OR equal to)

so let me put it like this:

18+1<26 yes because 18+1=19 which is less than 26

18+2<26 yes because 18+2=20 which is less than 26

18+3<26 yes because 18+3=21 which is less than 26

18+4<26 yes because 18+4=22 which is less than 26

18+5<26 yes because 18+5=23 which is less than 26

18+6<26 yes because 18+6=24 which is less than 26

18+7<26 yes because 18+7=25 which is less than 26

18+8<26 NOOO because 18+8=26 which is NOT less than 26 (it's equal, not less than)

when we multiply the equation and subtract equatio 2 from equation 1 the result is 0=-4 and 0=2

Answer:  The correct option is

Step-by-step explanation:  We are given to find the solution of the following system of equations :

[tex]-2x-y=1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)\\\\-4x-2y=-1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(ii)[/tex]

From equation (i), we have

[tex]-2x-y=1\\\\\Rightarrow y=-2x-1~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]

Substituting the value of y from equation (iii) in equation (ii), we get

which can never be possible.

Thus, the given system of equations have no solution.
