Answer: -1
Step-by-step explanation:
-8 (-8x - 6) = -6x - 22
distribute
64x + 48 = -6x -22
get rid of the smallest x by adding 6x to both side
70x + 48 = -22
minus 48 to both sides
70x = -70
divide both side by 70
x = -1
Which equation is NOT equivalent to 5 + n = 10. Select all that apply.
5 + n -n = 10 – n
5 + n – 5 = 10 - 10
5 + n – 5 = 10 - 5
5 + n + 3 = 10 + 3
5 + n – 10 = 10 - 5
Answer:
5 + n - 5 = 10 - 10
Step-by-step explanation:
if you do 5-5 that would equal zero, and if you do 10-10 it would equal 0 also, so all you would be left with is 0 + n= 0 and that is not equal to 5 + n = 10
Answer:
5 + n - 5 = 10 - 10
Step-by-step explanation:
Stacy buys 3 CDs in a set for $30.38. She saved $6.34 by buying the set instead of buying the individual CDs.
If each CD costs the same amount, how much does each of the 3 CDs cost when purchased individually?
Each CD costs $--------
each CD costs $12.24 when sold individually
1. we add together 30.38 and 6.34 to get the full price when purchased individually
2. then you would divide $36.72 by three to get the individual cd price which is $12.24

Jason loves to play the piano but doesn't like practicing the exercises his piano teacher assigns. Jason knows the exercises will help him play better though, so he tries to motivate himself using his favorite treat — chocolate chip cookies. Jason gives himself 5 cookies for every hour he practices.
There is a proportional relationship between the amount of time (in hours) that Jason practices the piano, x, and how many cookies he gives himself, y.
Graph this relationship. Select two points to draw a line.
What is the slope of the line?

Find the constant of proportionality of the table and express it in an equation
Answer:
The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour
Step-by-step explanation:
The constant of proportionality is y/x. Since flour comes second, we'll plug flour in for y here.
5/2 = 2.5
15/6 = 2.5
20/8 = 2.5
The constant of proportionality is 2.5. This can be expressed as (cups of sugar) * 2.5 = cups of flour
