Answer 2

The number line shows the distance in meters of two divers, A and B, from a shipwreck located at point X:


a horizontal number line extends from negative 3 to positive 3. The point labeled as A is at negative 2.5, the point 0 is labeled as X, and the point labeled B is at 1.5

Write an expression using subtraction to find the distance between the two divers. (5 points)

Show your work and solve for the distance using additive inverses. (5 points)
@geny55

Answer 3

b is 1.5 away from x and a is 2.5 away from x

Answer 4

you did this what was your answer?

Answer 5

You added the amount of units A was away from zero bc that is where X is and then you added the amount away from x to B

Answer 6

0 - 1.5=-1.5
2.5 - 0= 2.5

Answer 7

write it out like
A)...
B)...

Answer 8

A ) 1.5
B ) 2.5

Answer 9

show your work for b plz

Answer 23

A jar contains 0.75 liter of blackberry juice and 0.60 liter of blueberry juice. Patrick poured 0.25 liter of guava juice into the jar. He then drank 0.20 liter of the mixture.

Part A: Write an expression to represent the total amount of juice left in the jar. (5 points)

Part B: Identify which property is used in each step to simplify the expression. (5 points)

Answer 24

for part A is {(0.75+0.60)+0.25}- 0.20

Answer 25

good?

Answer 26

look lets do this

Answer 27

yup

Answer 28

I need b

Answer 29

what is:
0.75+0.60+0.25=...?

Answer 30

1.6

Answer 31

ok! Now we have subtract 0.2 liters, so we can write:
1.6-0.2=...?

Answer 32

@OregonDuck

Answer 33

yeah i am back

Answer 34

what is b

Answer 35

ok! Now we have subtract 0.2 liters, so we can write:
1.6-0.2=...?

Answer 36

1.4

Answer 37

what is the answer to b?

Answer 38

just continue with me

Answer 39

ok! that's right. That's your answer to the first part of your question

Answer 40

ok

Answer 41

now lets do the next part

Answer 42

at the first step, we have applied the associative property of addition, since we have wrote this:
(0.75+0.60)+0.25=1.60

Answer 43

sorry it glitched

Answer 44

yeah

Answer 45

at the second step, we have computed a subtraction, so we have applied the rule in order to perform a subtraction

Answer 46

done!

Answer 47

what is b?

Answer 48

b is :
at the first step, we have applied the associative property of addition, since we have wrote this:
(0.75+0.60)+0.25=1.60
at the second step, we have computed a subtraction, so we have applied the rule in order to perform a subtraction

Answer 49

ok

Answer 50

The elevation of city A is 72 feet above sea level; the elevation of city C is 24 feet above sea level. The elevation of city D is 1 over 4 of the elevation of city C.

Part A: Write an expression to represent the elevation, in feet, of city D. (5 points)

Part B: Simplify the expression and explain why the answer is negative or positive. (5 points)

Answer 51

Part A :
D = (1/4) * C
D = 1/4 * 24
D = 24/4 = 6 ft above sea level

Part B : Your answer is positive because D is still above sea level...if it would have been below sea level, then it would have been negative

Answer 52

thxs

Answer 53

The temperature of a city changed by −12 degrees Celsius over a 2-week period. The temperature changed by the same amount each week.

Part A: Write an expression to show the average change in the temperature of the city each week. (5 points)

Part B: Simplify the expression and explain, using words, what your answer means. (5 points)

Answer 54

last one

Answer 55

ok

Answer 56

you would have, t=-6w (temperature = -6 degrees multiplied by the week)you can simplify this to, -6=t/w which gives you negative six is equal to the temperature divided by the weeks

Answer 57

that a?

Answer 58

is that a?

Answer 59

hold on

Answer 60

kk

Answer 61

i dont know this one :(
