Answer:

Step-by-step explanation:

If angles C and B have equal degrees then the side AC is also equal to side AB in length and you can make their equations equal as well and solve for X.

2x+16=7x+6

get X's all on same side and the constants all on the other side,

-2x +2x+16=7x+6+-2x

The X's on the left cancel out.

16=5x+6

-6+16=5x+6+-6

add -6 to each side. On the right the 6 is now cancelled out.

10=5X

divide each side by 5 to cancel out the 5

10/5= 5X/5

2=X . ANSWER

The bike store marks up the wholesale cost of all of the bikes they sell by 30%.

Dmitrij [34]

Answer:

Suppose that the wholesale of a bike is A (A is the 100% in this case). If we have an increase of 30% for the sale price, we have the new price of:

Price = A + (30%/100%)A = A + 0.3*A = (1.3)*A

Then if we know that the price tag of the bike is $125, then we have:

$125 = (1.3)*A

$125/1.3 = A = $96.15

The wholesale cost of the bike is $96.15

Jane runs 6 miles in 44 minutes. At the same rate, how many minutes would she take to run 9 miles?

polet [3.4K]

Answer:

66 minutes

Step-by-step explanation:

<u>Solve for speed</u>

speed = distance / time

speed = 6 / 44

<u>Substitute in speed to second equation and solve for time</u>

distance / speed = time

9 / (6/44) = time

66 = time taken
