You are standing at the top of the mountain 1,500 feet above sea level and your brother is a scuba diving in the ocean 10 feet below sea level. Write an expression using absolute values to determine the difference between the 2 positions.
Answers
Answer:
To find the absolute value remove abt negative sign in front of a number and to think of all numbers as a positive
Step-by-step explanation:
The expression using absolute values to determine the difference between the two positions is → d = x + |y| , where : x = +1500 and y = -10.
What are expressions?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators
Given is that you are standing at the top of the mountain 1,500 feet above sea level and your brother is a scuba diving in the ocean 10 feet below sea level.
For 1500 feet above the sea level, we can write -
{x} = + 1500 ft
For 10 feet below the sea level, we can write -
{y} = - 10
Assume the difference between the two positions is equal to {d}. So, we can write -
d = x + |y|
d = 1500 + |- 10|
d = 1500 + 10
d = 1510 ft
Therefore, the expression using absolute values to determine the difference between the two positions is → d = x + |y| , where : x = +1500 and y = -10.

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

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.

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.)

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)

h + 86.43 = 531.79
h = ___________
Answers
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
