Solve for x<br> -2x + 4 = 6x - 12
aleksklad [387]

Answer:

x=2

Step-by-step explanation:

-2x+4=6x-12  Add 2x to both sides.

<u>+2x    +2x</u>

4=8x-12         Add 12 to both sides.

<u>+12  +12</u>

16=8x            Divide by 8 on both sides.

<u>/8 /8</u>

2=x

Hope this helps you out and have a great day (~^▽^)~

Jason jogged 2/3 mile in 1/3 hour. What was his speed in miles per hour?
fenix001 [56]

Answer:

I honestly was having the worst time trying to solve this sorry :(, for real idk if any of these are right

i got 2 answers; 1st: ≈0.5 mph

the 2nd; 2 mph

Step-by-step explanation:

Speed = \frac{Distance}{Time}

2/3 miles = 3520 feet

1/3 hours = 20 minutes

------Make a proportion-----

\frac{3520ft}{20min} = \frac{1 mi=5280 ft}{1hr = 60min}

cross multiply------

3520 * 60 = 211200

5280 * 20 = 105600

Divide \frac{211200}{105600}= 2

---(this is where i got confused cuz 2 doesn't make any sense)--

If you flip them, \frac{105600}{211200}=0.5 which makes more sense

hope i helped :(
