Answer:

Step-by-step explanation:

Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0

f(m)=20-0.25m

0 =20-0.25m

-20 = -0.25m

m = -20/-0.25

m = 80

Hence Trudy will have talked for 80minutes if she has no money left

Answer:

D

Step-by-step explanation:

because 5x4= 20 and -3×2=-6 so you need it to equal -6 and C20÷C26 you subtract so it gives you -6

I think this is right but I maybe be wrong

Answer:

He took 5 swimming classes.

Step-by-step explanation:

The problem states that the student paid a total of $56.25 for the classes and also the one-time registration fee. To find the number of classes, we should first subtract the one-time registration fee from the total.

$56.25 - $12.50 = $43.75

Now that we know he spent a total of $43.75 on the classes without the registration fee, we can divide that number by the cost of one class ($8.75) to calculate the total number of classes he took.

43.75 / 8.75 = 5

0.5 because there are 4 numbers and 2 of them are even so it would be 1/2

Answer:

[tex](-7_{s})^3[/tex]=  -343s

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) Let the number be y

45%of y=63

45y/100=63

Y=6300/45

Y=140

So 80%of a number =80y/100

=80×140/100

=112.

Let the number be y

35%of y=49

35y/100=49

Y=4900/35

Y=140

So 80%of a number =80y/100

=80×140/100

=112.

Answer:

In arithmetic, variables look like letters.

Step-by-step explanation:

As we know that Mathematical arithmetic deals with numbers and certain properties with them.

Some of the main properties between numbers are as follows:

Variables do not remain constant, so we basically assign a number to a variable with an equal operator denoted by '='.

For example, let us assume a variable x being equal to 7. so it can written as:

[tex]x = 7[/tex]

Let suppose the value of the variable x=7 changes to x=10, then the new value will be:

[tex]x = 10[/tex]

Therefore, the correct answer is:

In arithmetic, variables look like letters.

Answer: x = 160

Step-by-step explanation:

540 = 100+(x-25)+(x-15)+(1/2)x+(1/2)x

540= 100-40+3x = 60+3x

480 = 3x

x = 160

Answer:

0.5x + 0.5x + (x-25) + (x-15) + 100 = 540

x + x - 25 + x - 15 + 100 = 540

3x + 60 = 540

3x = 540 - 60

3x = 480

x = 480/3

x = 160

The answer is going to be 5162.

Answer:

because 8/4=2

Step-by-step explanation:

4/4=1

8/4=2

it's because the numerator is bigger if it were 6/4 it would be a mixed number but the eight goes in to 4 directly 2 time so therefore it's 2.

Answer:

y = 3/4x - 1/4

Step-by-step explanation:

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

Work Shown:

For now, let's assume they are equal. We'll show a contradiction happens.

5/6 = 2/3

5*3 = 6*2 ... cross multiply

15 = 12 ... here's the contradiction

If the original equation was true, then we would get the same thing on both sides in the final step shown above. However, we get a contradiction, so that means the original equation is false.

Furthermore, the left side is larger in the third step, so the left side is larger for each of the three steps. We can then say

5/6 > 2/3

5*3 > 6*2

15 > 12

Which helps show 5/6 is larger than 2/3.

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

Or you can use a calculator to see that

5/6 = 0.833 approximately

2/3 = 0.667 approximately

which shows the two fractions aren't equal and 5/6 is larger.

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 4, 3) and (x₂, y₂ ) = (5, 3)

m = [tex]\frac{3-3}{5+4}[/tex] = [tex]\frac{0}{9}[/tex] = 0

Answer:

B

Step-by-step explanation:

35% of this price is :

35/100 × x = 0.35x

The price reduces by 0.35x.

This equals to 115.65

Now :

0.35x = 115.65

100/35 × 115.65 = 330.43
