Teresa purchased a prepaid phone card for $15 . Long distance calls cost 24 cents a minute using this card. Teresa used her card only once to make a long distance call. If the remaining credit on her card is $3.96 , how many minutes did her call last?

i believe the answer is 35 dimes and 65 nickels (sorry if i’m wrong lol)

Answer:

Step-by-step explanation:

Using slope formula and solving for y

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

Answer:

y = 2

Step-by-step explanation:

Using slope formula and solving for y

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

-2/7 = (4 - y)/(3 - 10)

-2/7 = (4 - y)/-7

2 = 4 - y

y = 4 - 2

y = 2

Answer:

40 and 28

Step-by-step explanation:

We have two unknown numbers, so let's call them x and y for now.

We know the sum of the two numbers is 68, and the difference is 12, so let's substitute those two numbers for x and y:

x+y=68

and

x-y=12

Because both of these systems are true, we can take both these equations and combine them, by adding each side of one equation with the corresponding side of the other.

So we have:

(x+y)+(x-y)=(68)+(12)

2x=80

x=40

Now we know one of the numbers, x, is equal to 40, so now we can plug that number back into one of the two original equations, x+y=68 or x-y=12. I'll choose x-y=12.

After plugging in x, we get:

40-y=12

-y=-28

y=28

So now we have figured out x and y, which are 40 and 28.

Step-by-step explanation:

Answer: 12 inches

Step-by-step explanation:

Because 19 inches costs 76 cents. If you divide 19/19 you get 1 inch. Also divide 76/19 and you get 4 cents. Now it’s asking how many inches could be bought for 48 cents. So 48/4 equals to 12 and that’s your answer. You see 19x4=76. And 12x4= 48. I hope that helped you.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Starting point = 18 inches

Rate or speed = 3 inch per minute

t = number of minutes since climbing began

When will worm be more than 60 inches above the ground.

Height (t) = starting point + (rate * time)

18 + 3t > 60

3t > 60 - 18

3t > 42

t > 42/3

t > 14

Hence, inequality to use is : 60 > 18 + 3t

Step-by-step explanation:

2(x+6)=3(x+1)

2x+12=3x+3

collect the like terms

2x + 3x = 3+12

x=15/5=3

or

2x-3x = 3-12

= -9

Answer:

Step-by-step explanation:

Let x=smaller number

Then x+5=larger number

Now we are told the following:

1/5(x+x+5)=x-5 multiply each side by 5

x+x+5=5x-25 subtract 5x and also 5 from both sides

x+x+5-5-5x=5x-5x-25-5 collect like terms

-3x=-30 divide both sides by -3

x=10-----------------------smaller number

x+5=10+5=15 ---------larger number

CK

1/5(10+15)=10-5

1/5(25)=10-5

5=5

Answer:

Step-by-step explanation:

d /d x [ a ^x ]

= d/ d x [ e ^ln ( a ) x ]

= e ^ln ( a ) x ⋅ d /d x [ ln ( a ) x ]

= e ^ln ( a ) x ⋅ ln ( a ) ⋅ d /d x [ x]

= e ^ln (a ) x ln ( a ) ⋅ 1

= ln ( a ) e ^ln ( a ) x

Rewrite/simplify:

= a ^x ln ( a )

Answer:

x=[tex]\frac{m}{k-n}[/tex]

Step-by-step explanation:

First you subtract nx from both side getting kx-nx=m.

Then you factor out x getting x(k-n)=m

and now you divide both sides from (k-n) and you will get the answer.

Answer:

equation written in the form Ax + By = C where A and B are coefficients and C is the constant. assigns each input value, one output value. rate that describes how one quantity changes in relation to another quantity. rate of change between any two quantities is the same, or constant.

Step-by-step explanation:

The Slope of the equation represents the constant rate of change.

For example: in the equation [tex]y=3x+9[/tex]      [tex]3[/tex] is the slope

Answer:

157.5 pages

Step-by-step explanation:

First, find your rate. You want to know how many pages you can read per minute. We can use any nuber, but using 2 minutes will be the simplest solution:

2m = 7

---      ---      <---- Here we divide both sides of the equal sign by 2

2        2

m = 3.5 <---- we read 3.5 pages per minute

45 x 3.5 = 157.5 (We multiplied 45 because it's the number of minutes we have, by the 3.5 pages we read each minute. This gives us our total of 157.5 pages in 45 minutes.
