8 0

Answer:

2k

Step-by-step explanation:

3k and -k are both like terms, so you can combine them. Adding opposite signs works in the same way as subtraction, so you can rewrite the expression as 3k-k, which is 2k.

Bodie Raptor's Iphone 11 has 4/5 of the battery still remaining. His phone battery drains at a rate of 1/3 every hour. If he use
Nikolay [14]

Answer:

2\frac{2}{5} hours, or 1 hours and 24 minutes

Step-by-step explanation:

4/5 battery remaining

drains at rate of 1/3 per hour

\frac{1}{3}h=\frac{4}{5}\\\frac{3}{1}(\frac{1}{3}h)=\frac{3}{1}*\frac{4}{5}\\h=\frac{3*4}{1*5}=\frac{12}{5}=2\frac{2}{5}

He has 2 2/5 hours or 2 hours and 24 minutes left until his phone dies.  (A fifth of an hour is 12 minutes and we have 2/5 to deal with, so 12 times 2 is 24 mins.)

How do you solve x(x+h)=x-h for h?
WITCHER [35]

Answer: H = \frac{-x^{2}+x }{x+1}

Step-by-step explanation:

Step 1: Add h to both sides.

hx+x²+h=−h+x+h

hx+x²+h=x

Step 2: Add -x^2 to both sides.

hx+x²+h+−x²=x+−x²

hx+h=−x²+x

Step 3: Factor out variable h.

h(x+1)=−x²+x

Step 4: Divide both sides by x+1
