Verizon offers a cell phone plan where customers buy a cell phone for $300 and pay a monthly fee of $40. T- Mobile offers a cell phone plan where customers buy a cell phone for $200 and a monthly rent of $60. Write the equation needed to find the number of months a customer would have to own a cell phone in order for the two cell phone companies to be equal. PLEASE ANSWER QUICKLY. need help!!!

Answers

Answer:

A customer would have to own a cell phone for 5 months in order for the two companies to be equal.

Step-by-step explanation:

Given that:

Cost of cell phone at Verizon = $300

Monthly fee = $40

Let,

x be the number of months

V(x) = 40x + 300

Cost of cell phone at T-mobile = $200

Monthly fee = $60

T(x) = 60x + 200

For equal amount of money,

V(x) = T(x)

40x+300=60x+200

300-200=60x-40x

100=20x

20x=100

Dividing both sides by 20

[tex]\frac{20x}{20}=\frac{100}{20}\\x=5[/tex]

Hence,

A customer would have to own a cell phone for 5 months in order for the two companies to be equal.

Kate's math homework had a set of equations and a one-word problem. She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total, how many equations did she solve

Answers

Answer:

15 equations

Step-by-step explanation:

Let

Number of equations in the homework = x

There is only a one-word problem

y = amount of time used to solve the word problem

She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,

Total = 3x + y

52 = 3x + 7

Subtract 7 from both sides

52 - 7 = 3x + 7 - 7

45 = 3x

Divide both sides by 3

x = 45 / 3

= 15

x = 15 equations

Therefore, she solved 15 equations

you flip a coin twice what is the probability of getting tails then getting heads

HELP ASAP

Answers

Answer: The odds of getting tails twice in a row are 1/2 * 1/2 = 1/4. So 25% of the time you'll get heads twice in a row. But, if you've already flipped a coin 99 times, and gotten heads each time, then the odds of your next flip being heads is still just 50:50.

Find the x and y Intercepts

Answers

Answer:

x-intercept(s): (3,0)

y-intercept(s): (0,−2)

Step-by-step explanation:

Answer:

x=3 and y=-2

Step-by-step explanation:

2x - 3y = 6

cancel out the y

2x - 3(0) = 6

2x = 6

divide both sides by 2

x = 3

2x - 3y = 6

cancel out the x

2(0) - 3y = 6

-3y = 6

divide both sides by -3

y = -2

Find the measure of <1

Answers

Consider the triangle (in which angle4 is present)

by angle sum property,

20 + 40 + angle4 = 180

60 + angle4 = 180

angle4 = 180 - 60

angle4 = 120

Also,

angle2 = 120 (vertically opposite angles)

angle1 + angle2 = 180 (linear pair)

angle1 + 120 = 180

angle1 = 180 - 120

angle1 = 60

Harper is making pudding cups for a big celebration. She made 5 pounds of pudding, but she needs to separate the pudding into individual 4-ounce cups. How many total individual pudding cups can Harper make?

Answers

Given :

Total amount of pudding made, T = 5 pounds.

Size of each cup, s = 4 ounces.

To Find :

How many total individual pudding cups can Harper make.

Solution :

Let, n number of pudding cups can filled with 5 pounds pudding.

We know, 1 pound = 16 ounces.

So, 5 pounds = 16×5 = 80 ounces.

Now,

[tex]n = \dfrac{80}{s}\\\\n = \dfrac{80}{4}\\\\n = 20 \ cups[/tex]

Therefore, 20 cups can be filled with 5 pounds of pudding.
