Solve the following system of equations using substitution.
y = 2x-2
-4x-y = 26

Answers

Answer:

x = -4

y= -10

Step-by-step explanation:

Solving for x

-4x-y = 26

-4x-(2x-2) = 26

-6x+2 = 26

-6x = 24

x = -4

Solving for y

y = 2x-2

y = 2(-4) -2

y= -8-2

y = -10

Half a pepperoni pizza plus three fourths of a ham-and-pineapple pizza contains 765 Calories. One fourth of a pepperoni pizza plus a whole ham-and-pineapple pizza contains 745 Calories. How many Calories are in a whole pepperoni pizza? How many Calories are in a whole ham-and-pineapple pizza?

Answers

Answer:

Let x be the number of calories in the pepperoni pizza and y be the number of calories in ham-and-pineapple pizza. Then, we can make two equations out of the problem statement.

Eq 1: (1/2)x + (3/4)y = 765

Eq 2: (1/4)x + y = 745

By transposing, Eq 2 becomes: y = 745 - (1/4)x. We substitute this to Eq. 1:

(1/2)x + (3/4)(745 - (1/4)x) = 765

x = 660

Then we substitute x to Eq 2 to get y:

y = 580

Thus, there is 660 calories in pepperoni pizza and 580 calories in ham-and-pineapple pizza.

feed the team. Pizzas are $7.25 for a small pizza and $10.50 for a large pizza. Let:
S = number of small pizzas he can buy & L = number of large pizzas he can buy.
Select the system of inequalities that represents this situation.

Answers

Answer:

7.25S + 10.50L ≤ 90

The system of inequalities that represents a given situation are  S+L>5 and 7.25S+10.50L≤90.

Given that, For a soccer party, Juan collects $90 for pizza. He must buy more than 5 pizzas to feed the team. Pizzas are $7.25 for a small pizza and $10.50 for a large pizza.

What are inequalities?

Inequalities are mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Let S = the number of small pizzas he can buy and L = the number of large pizzas he can buy.

Juan must buy more than 5 pizzas to feed the team.

That is, S+L>5

Pizzas are $7.25 for a small pizza and $10.50 for a large pizza=7.25S+10.50L

Juan collects $90 for pizza. So, 7.25S+10.50L≤90

Therefore, the system of inequalities that represents a given situation are  S+L>5 and 7.25S+10.50L≤90.

A hybrid car can travel 40 miles per gallon. Approximately how many gallons of fuel will the car need to travel 20 km? (5 points) [1 mile = 1.6 km]

Answers

Answer:

To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.

Step-by-step explanation:

Proportions

The hybrid car can travel 40 miles per gallon.

Since one mile is equivalent to 1.6 Km, the distance traveled per gallon is 40*1.6 = 64 Km.

Now the distance is expressed in Km, we can find the gallons needed to travel 20 Km, by calculating 20/64 = 0.3125.

To travel 20 Km, the hybrid car needs 0.3125 gallons of fuel.

Find the slope by using 2 sets of x,y values from the table.

Slope is change in y over change in x:

Slope = (-6 - -9) / (1 - -2) = 3/3 = 1

Given y=2x+1 work out y x=4 From "The Tyranny of Things" by Elizabeth MorrisTwo fifteen-year-old girls stood eyeing one another on first acquaintance. Finally one little girl said, "Which do you like best, people or things?" The other little girl said, "Things." They were friends at once.I suppose we all go through a phase when we like things best; and not only like them, but want to possess them under our hand. The passion for accumulation is upon us. We make "collections," we fill our rooms, our walls, our tables, our desks, with things, things, things.Many people never pass out of this phase. They never see a flower without wanting to pick it and put it in a vase, they never enjoy a book without wanting to own it, nor a picture without wanting to hang it on their walls. They keep photographs of all their friends and kodak albums of all the places they visit, they save all their theater programmes and dinner cards, they bring home all their alpenstocks. Their houses are filled with an undigested mass of things, like the terminal moraine where a glacier dumps at length everything it has picked up during its progress through the lands.But to some of us a day comes when we begin to grow weary of things. We realize that we do not possess them; they possess us. Our books are a burden to us, our pictures have destroyed every restful wall-space, our china is a care, our photographs drive us mad, our programmes and alpenstocks fill us with loathing. We feel stifled with the sense of things, and our problem becomes, not how much we can accumulate, but how much we can do without. We send our books to the village library, and our pictures to the college settlement. Such things as we cannot give away, and have not the courage to destroy, we stack in the garret, where they lie huddled in dim and dusty heaps, removed from our sight, to be sure, yet still faintly importunate.Then, as we breathe more freely in the clear space that we have made for ourselves, we grow aware that we must not relax our vigilance, or we shall be once more overwhelmed.For it is an age of things. As I walk through the shops at Christmas time and survey their contents, I find it a most depressing spectacle. All of us have too many things already, and here are more! And everybody is going to send some of them to everybody else! I sympathize with one of my friends, who, at the end of the Christmas festivities, said, "If I see another bit of tissue paper and red ribbon, I shall scream."It extends to all our doings. For every event there is a "souvenir." We cannot go to luncheon and meet our friends but we must receive a token to carry away. Even our children cannot have a birthday party, and play games, and eat good things, and be happy. The host must receive gifts from every little guest, and provide in return some little remembrance for each to take home. Truly, on all sides we are beset, and we go lumbering along through life like a ship encrusted with barnacles, which can never cut the waves clean and sure and swift until she has been scraped bare again. And there seems little hope for us this side our last port.And to think that there was a time when folk had not even that hope! When a mans possessions were burned with him, so that he might, forsooth, have them all about him in the next world! Suffocating thought! To think one could not even then be clear of things, and make at least a fresh start!
