Answer: AB = 9

Step-by-step explanation:

Since B is the midpoint,  AB and BC must be congruent (since theyre both half of the segment). The equation is:

2x + 5 = 5x - 1

This means x = 2, meaning AB is 9.

Nick opens a savings account with $50. Each week after, he deposits $15. He wants to save $500. Write and solve equation to find
Alborosie

Answer:

Equation: 500 = 50 + 15x

Step-by-step explanation:

where x is the number of weeks Nick will have to deposit $15 in order to accumulate $500, given that the first week he deposited $50.  

500 = 50 + 15x

500 = 50 + 15x

450 = 15x

x = 30

 

Now Nick will have to deposit $15 each week for 30 weeks.   This is in addition to the $50 deposit he made week 1.  So it will take him 31 total deposits to accumulate the $500.

You are shopping for carpet for your living room which measures 19 feet by 12 feet. Charlie's Carpets sells carpet for $18 per s
Kamila [148]
----------------------------
Charlie's Carpets:
----------------------------
Carpet : $18/yd
Installation: $2/yd

Discount: 20% x $18 = 0.2 x 18 = $3.60
Carpet Price after discount = $18 - $3.60 = $14.40/yd²

Carpet Price with installation $14.40 + $2 = $16.40/yd²

----------------------------
Cindy's Carpet
----------------------------

Carpet = $18/yd²

Discount = 10% = 0.1 x $18 = $1.80
Price after Discount = $18 - $1.80 = $16.20/yd²

----------------------------
Summary:
----------------------------
Charlie's Carpet = $16.40/yd²
Cindy's Carpet = $16.20/yd²

CIndy's Carpet is cheaper.

----------------------------
Find Cost:
----------------------------

Width = 12 x 1/3 = 4 yards

19/3 x 4 = 25 1/3 yd²

Cost = 25 1/3 x $16.20 = $410.40

------------------------------------------------------------------------------------
Answer: Cindy's Carpet is cheaper and it will cost $410.40.
