Answer:
X = 5
Step-by-step explanation:
3x + 12 + 9x = 72
okay hopefully i can explain so when your doing this combine like terms so
3x + 9x = 12x
12x + 12 = 72
then you would subtract both sides by 12
+12 = subtract x+12=2
- 12 = add x-12=2
there just flipped so in this case i would subtract 12
12x + ( 12-12) = ( 72-12 )
so 12-12 = 0 and 72-12 is equal to 60
12x = 60
the divide on both sides l but leave the x alone so its just 60 divided by 12 wich is 5
so X = 5
hope this helps with ur homework a little btw go back and redo ur other awnsers with this new concept hope it helps
Hey! First you do 120 divided by 4 which equals 30 then you do 30 x 3 which is 90 which equals 90. So they won 90 games and lost 30 games.
Hope this helps!

Step-by-step explanation:
Amount after 2 years = Principal + interest
Get the interest
Interest = PRT/100
Interest = 3003 * 9 * 2/100
Interest = 3003 * 18/100
Interest = 30.03 * 18
Interest = 540.54
Amount after 2 years = 3003 + 540.54
Amount after 2 years = £3,543.54
Answer:
Jayln rode 12.4 miles/hour.
Step-by-step explanation:
The question is asking for a unit rate for the speed in miles per hour that Jayln rode her bike over her 33.48 mile ride. Since we know that she rode a total of 33.48 miles and the total time was 2.7 hours, we can set up our ratio as 33.48/2.7 or miles/hours. In order to find unit rate, or the number of miles per one hour, we need to divide: 33.48 ÷ 2.7 = 12.4. So, 12.4 mph is Jaylyn's speed.
