One market sells a 3-kilogram bag of tortillas for 45 pesos, and the second market sells 2 kilograms of tortillas for 22 pesos.

Which unit price is lower? / Would I subtract 2 kilo from 22 pesos?

Answers

Answer:

The second market is cheaper

Step-by-step explanation:

For the first market:

If the 3Kg = 45 pesos

then 1Kg = 15 pesos because you divide it by 3

In the same way for the second market:

2Kg = 22pesos

so 1Kg is 11 pesos as you divide it by 2.

Therefore the second market is cheaper as the unit price is lower.

h + 86.43 = 531.79

h = ___________

Answers

h= 445.36
because you bring the 86.43 over to the 531.79. which would make 86.43 a negative number. so you subtract 531.79 by 86.43

Answer:

h=445.36

Step-by-step explanation:

Subtract both sides by 86.46

531.79 - 86.43 = 445.36

Check answer by plugging it back in

445.36 + 86.43 = 531.79

Which of these systems of equations would be best solved using the subtraction​ method?
I. 2x−7y+3y = 4 −6x−4y = −52
II. 2y = −5x+6x−5 y = 2x−6
III. −7x+3x+2y = 4 4x−6y = −52

Answers

Answer:

Step-by-step explanation:

1. x+2y=6 or x=6-2y

3x-2y=2

3(6-2y)-2y=2

18-6y-2y=2

18-8y=2

-8y=-18+2

-8y=-16

y=-16/-8

y=2 ans.

x+2*2=6

x+4=6

x=6-4=2 ans.

Proof:

3*2-2*2=2

6-4=2

2=2

I leave the rest for you to practice with.

3. 4x+y=7

2x+5y=-1

 

5. 3x+2y=-2

7. -3x+3y=3

---------------------------------

4y=12

y=12/4

y=3 ans.

3x+3=9

3x=9-3

3x=6

x=6/3

x=2 ans.

Proof:

-3*2+3*3=3

-6+9=3

3=3

I'll leave the rest for practice.

y=3x+14
2x-3y=-14
Substitution method

Answers

Answer:

x = -8

Step-by-step explanation:

y = 3x + 14

2x - 3y = -14

So, what is the substitution? Y of course, this is because y is equal to 3x + 14.

2x - 3 (3x + 14) = -14

Multiply 3 with the numbers in the parentheses.

2x - 9x + 42 = -14

So you maybe be wondering why it is a negative 7 instead of subtracting 9 with 2. Using PEMDAS, we always read from left to right. So it is basically 2 -9 and you get -7.

-7x + 42 = -14

Then subtract 42 from both sides.

-7x + 42 - 42 = -14 - 42

Simplify

-7x = -56

Divide 7 by both sides.

-7x / 7 = -56 / 7

x = -8

And you might ask, why we get x instead afterwards. This is because both -7 and 7 cancel each other out leaving us with x.

X=-8

Questions are in the Picture

Answers

Answer:

Step-by-step explanation:

For problem 10:

1. AE/ED=AC/CB (Since triangle ABC is similar to triangle ADE, we can determine that the ratio of AE to ED is equal to the ratio of AC to CB)

2. AE/ED=(AE+EC)/CB (Rewrite AC as the sum of the lengths forming it; This is sometimes referred to as the Partition Postulate)

3. 9/x=(9+6)/10 (Substitute the given values into this equation)

4. x=6 (Use algebra to solve for x)

For problem 11:

1. AG/AB=AE/AD (Use the same strategy as step one in problem 10, since the rectangles are similar we can create this equation)

2. AG/(AG+GB)=AE/(AE+ED) (Rewrite sides as the some of their parts)

3. 14/(14+7)=18/(18+x) (Substitute given values)

4. x=9 (Solve for x)

Dr. Wong has a table of data in her veterinary office that shows the average lifespans and weights of several popular dog breeds. Alfonso made a scatterplot of these data for a math project.

Answer the questions to make predictions about the lifespan of a specific breed of dog.

1. Describe the association shown by this scatterplot.

2. Alfonso is thinking of getting a bloodhound. Bloodhounds usually weigh about 90 pounds. Based on the data, estimate for the lifespan of a bloodhound. Explain how you made your estimate.

3. Alfonso's friend Dani tells Alfonso that her bloodhound, Ol' Sniffy, lived to be 14.
Based on what you know, do you think this was because:

1. Alfonso didn't use a good estimation method,
2. Dani doesn't remember Ol' Sniffy's age correctly, or,
3. Ol' Sniffy lived an unusually long time?

Justify your answer.

Answers

Answer:

1. The heavier the dogs are, the shorter lifespan they have.

2. The lifespan of a bloodhound is on average 10 years long

3. Number 2

Step-by-step explanation:

#1 explination: Since its obvious that the graph angles downwards as it goes towards the left, and because as you go to the left you get heavier dogs, put 2 and 2 together and you get my answer.

#2 explination: We see 3 dots around 90 pounds, one that lives 11 years, and 2 that live 10 years. Since we need to be accurate, we need to find the average of 10, 11, and 10. (10+10+11)/3=10.33. Now we round to 10, so 10 is our answer.

#3 explination: Since there is a bloodhound that lives to be 14, we have two answers, 2 or 3. 1 doesn't work since if Alfonso doesn't have good estimation, the first two questions wouldn't matter *the more you know*. Since we see no unusual pattern between any of the three dots I mentioned earlier, Dani must of forgotten her dog's age (probably because of that dog years thing.)
