Answer:
Step-by-step explanation:
=> 8.2x + 9y + 2(2.5x) + 10xy
=> 8.2x + 9y + 5x+ 10xy
=> 13.2x + 9y + 10xy
Since we can't simplify it from here, 13.2x + 9y + 10xy is our answer.
Answer:
120 cm
Step-by-step explanation:
1/2 is 6 months and 6 years are 72 months.
Using the rule of three, 10 cm is to 6 months what x is for 72 months so
x = (72 * 10) / 6 = 120
2.34+(-2/7)+(-.45)+3/8= Answer than divide by 4 and that will be your average
Ok all you got to do is divide so that all the numbers will be decimals
hope i helped
You know that you need two already to make one hexagon. So, if you multiply, or add two four times, 2+2+2+2, you would get eight.
