What is 72.1 repeating as a fraction? Simplified.

Viefleur [7K]

The answer is quite simple after looking at it. 0.1 is a tenth. 72 is a whole number, so you would have 72 1/10. 1/10 is a tenth and 72 is still the whole number.

HELP NEEDED!!! WILL GIVE 5 STARS!

Jlenok [28]

270=2b + a
420=2a + 3c (you have to use trial and error for this)

B = 120
A = 30
C = 120

Just to check
270 = (2x120) + 30
420 = (2x30) + (3x120)

Jenn went shopping and spent $112. She bought a book for $24 and CD's that cost $8 each. What equation would you use to find out

slavikrds [6]

I would use the equation
24 + 8x = 112

let x = the amount of CDs she bought.

Hope this helps!!

Algebra II

Distance Formula: $\displaystyle d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

Step-by-step explanation:

Step 1: Define

Identify.

Point (-7, 1)

Point (-7, -5)

Step 2: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d.

Substitute in points [Distance Formula]: $\displaystyle d = \sqrt{(-7 - -7)^2 + (-5 - 1)^2}$
[Order of Operations] Evaluate: $\displaystyle d = 6$
