Answer:
a=1/2 b=5/4 c=2^5/4 . ??
Step-by-step explanation:
I am not sure if the a is supposed to be a second exponent but I solved this as if it wasn't.
55 adult tickets. Set up 2 equations: c+a=125 and 6.1c+9.4a=944. Isolate either variable from first equation and plug into second to find that 55 adult tickets were sold and 70 children’s tickets
The two numbers are very near 7200 and 300. The sum of those is a good estimate of your sum:
... 7200 + 300 = 7500
_____
If you're taught methods of addition that include "make a ten" or "make a hundred", you know you can "borrow" a 1 from 7203 (making it 7202) and loan that 1 to 299 to make it 300. Now, you know your sum is exactly 7202+300 = 7502, with no estimation necessary.
4w +8. C.
It’s 4 * width for perimeter and two of the sides are longer by 4in so 2*4=8
