The table shows two options provided by high speed internet. option 1 have set up fee of $50 with $30 per month. option 2 have no set up fee and is $80 per month. in how many months will the total cost of both options be the same? what will that cost be? Define the variables x and y. Write an equation/equations using the variables.

Answers

Answer 1
Answer:

Answer:The total cost will be the same after 1 month. That cost will be $80. x= # of months, y= cost in dollars. Equation for option 1 is 30x+50. Equation for option 2 is 80x.

Step-by-step explanation: After finding the equations, you can solve them, graph them, or use a graphing calculator.

What is the sum of 1 minus 7\12

Think about this. You have one whole pie and you've just cut it into 12 pieces. How many pieces do you have left if you eat 7 of them? 5. That means you have 5/12 of the pie left, so your answer is 5/12.

Value of x in the solution to the system of equations.
6x+3y=13
3x-y=4

Answers

The two easiest ways to solve a system of equations (in my opinion) are to add the equations together while getting rid of a variable, or solving for a variable in one equation and plugging it into another. The latter is the method I will use.

3x - y = 4 (solve for y)
3x = 4 + y
3x - 4 = y
y = 3x - 4 

Now we can plug y into the other equation:
6x + 3y = 13
6x + 3(3x - 4) = 13
6x + 9x - 12 = 13
15x = 25
x = 25/15
x = 5/3
The answer is x = 5/3

If you ever needed to find y as well, you can plug this into either equation to find y.
3x - y = 4
3(5/3) - y = 4
5 - y = 4
y = 1

x/2 + x + x/3 = 8

Simplify both sides of the equation

x/2 + x +x/3 = 8

Simplify

11/6 x = 8

Multiply both sides by 6/11

(6/11)*(11/6 x ) = (6/11)*(8)

x = 48 / 11

decimal will be x = 4.36


-7(x-1)-3(x-4)

(-7)(x)+(-7)(-1)+(-3)(x)+(-3)(-4)

= -10x + 19


3(x-2)^2 -5(x-2)+3

= 3x^2 + -12x+12+(-5)(x)+(-5)(-2)+3

= 3x^2 +-12x+12+ -5x +10 +3

Combine like terms

3x^2 + -12x+12+ - 5x+10 +3

(3x^2) + (-12x+ -5x ) + (12+10+3)

= 3x^2 + -17x + 25

= 3x^2 -17x+25

A recipe for 8 servinfs of pudding clls for 2 cups of milk.How many gallons of milk are needed to make enough pudding for 64 servings

Answers

In order to solve this, we first need to know what the ratio of servings of pudding to cups of milk is. We can see that 8 servings of pudding requires 2 cups of milk, so the ratio is 8/2, which can be reduced to 4/1. This means that for every 4 servings of pudding, we will be adding 1 cup of milk. So all we need to do to find out how many cups would be needed for 64 servings of pudding, we simply need to divide by 4.

64 / 4 = 16

So for 64 servings of pudding, we will need 16 cups of milk. But that's not what the question wants to know, it wants to know how many gallons of milk it would need. 

In order to find that out, we have to know how many cups there are in one gallon. There are 2 cups in one pint, there are 2 pints in a quart, and there are 4 quarts in a gallon, so we just have to multiply those numbers, and we get 4 * 2 * 2 = 8 * 2 = 16

There are 16 cups in one gallon, therefore, 64 servings of pudding will require 1 gallon of milk.
Hope that helped! =)
