Mr. Levin tried to simplify this expression. He made a mistake! Explain where the mistake is in this problem. Give the correct simplified expression too! (8x + 8) - (7x - 2)
8x + 8 - 7x - 2
x + 6

Instead of x+6, it should be x+10

Step-by-step explanation:

His mistake is putting x+6.

Step-by-step explanation:

You can't add x to 6 because they are not the same.

The right answer is X=6.

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
