Answer:

Stephen Talked for 138 minutes.

Step-by-step explanation:

(0.10)m + 10.00 = 23.80         Given

              -10.00   -10.00      

            (0.10)m = 13.80          Subtraction Property of Equality

              /0.10       /0.10        

                      m = 138             Division Property of Equality

Answer: Sunny Horizon Cellular’s phone plan has a monthly fee of $10.00 and charges $0.10 for every minute used. Stephan’s bill for the month was $23.80. If the equation that models this situation is (0.10)m + 10.00 = 23.80, use inverse operations and properties of equality to find the number of minutes Stephan talked during the month.

Answer:

35000

Step-by-step explanation:

multiple the the cards per shipment by the number of shipments

7000x 5

=35000

Answer: Ok I have two ways for this

1. If you mean how many will there be for each shipment: 1,400

If you mean how many will there be for 5 shipments since there is 7,000 each shipment then 35,000

Step-by-step explanation:

1. 7,000 ÷ 5

2. 7,000 x 5

Take 2 points

Slope:-

[tex]\\ \sf\longmapsto \dfrac{-2}{7}=\dfrac{-2}{7}=m[/tex]

Now find equation of line in point slope form

[tex]\\ \sf\longmapsto y=-2/7(x+7)[/tex]

[tex]\\ \sf\longmapsto y=-2/7x-2[/tex]

Put (0,0)

[tex]\\ \tt\Rrightarrow 0=0-2[/tex]

[tex]\\ \tt\Rrightarrow 0\neq -2[/tex]

Answer:

Many solutions

Step-by-step explanation:

If it is manipulated, you simply get:

2x + 2x + 2 = 4x + 2

0 = 0

So, there are infinitely many solutions, as anything you plug in for x will be canceled as there are 4 x's on both sides.

Answer:

only students who have recess at 12 p.m. or later may go out

Step-by-step explanation:

Let the time after midnight be represented by t, and the temperature be y. Since the temperature increases by 1.2 degrees Fahrenheit each hour, the time taken to reach 32 degrees Fahrenheit can be gotten from:

y = 1.2t + 18

put y = 32

32 = 1.2t + 18

1.2t = 14

t = 14/1.2 = 11.67 hours

Since the recess starts at half hour or hour, hence the recess would start at t = 12 hours, i.e. at 12 p.m.

Hence only students who have recess at 12 p.m. or later may go out

Answer:

i know im late but here only students who have recess at 12 p.m. or later may go out

What is mean by Ratio?

A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.

Where, x and y are individual amount of two quantities.

And, Total quantity gives after combine as x + y.

Given that;

Olivia and Jessica have in total half as many sweets as Fran and Gary have in total.

Now,

Let Fran got w sweets.

Gary got x sweets.

Olivia got y sweets.

Jessica got z sweets.

So, We get;

⇒ (y + z) = 1/2 (x + w)    ..(i)

Here, w = 2a and x = 3a

And, y = 9b and z = b

Substitute in equation (i), we get;

⇒ (y + z) = 1/2 (x + w)    

⇒ (9b + b) = 1/2 (2a + 3a)  

⇒ 10b = 1/2 (5a)

⇒ 20b = 5a  

⇒ 10b = a

So, w = 20b and x = 30b

Or, w : x = 20b : 30b

So, w : x: y: z = 20b : 30b : 9b : b

                     = 20 : 30 : 9 : 1

Thus, The simplest form of w : x : y : z will be;

⇒ w : x : y : z = 20 : 30 : 9 : 1

Step-by-step explanation:

Divide them into two parts:

Normal drinks and commemorative drinks

- With normal, only $5.75 is related (Only one drink at a time so 5.75x)

- With commemorative, $22.99 and $2.09 are related (A one time fee of $22.99, then a refill of $2.09; so 22.99 + 2.09x)

Answer:

Step-by-step explanation:

The first thing is recognize that it is a rectangle and two triangles with given bases and heights.

So the first step is finding the area of both triangles, which you can do with the formula for the area of a triangle:

A = (BH)/2

Because the height is two, the area is going to be equal to the base.

The sum of the two triangles is 7.66.

Next you want to find the area of the rectangle, you can do so using the formula:

A = BH

A = 6(2)

The area of the rectangle is 13.

Find the sum of the areas of the three shapes.

3.30 + 4.36 + 12 = 19.66

Answer:

4.35 / 100 = 0.0435

Step-by-step explanation:

We find it useful to convert 4.35% to decimal, because if you need to find 4.35% of any number, you can simply multiply that number with 0.0435.
