oh boi, lets see...
-4^2
5 1/3 + (-3 1/2) = 2 183/100= 3 83/100
i would use liters or fluid ounces.
91 is composite.
i dont know mean or mode so i really cant help sorry
i would use miles
i can't help with that either. so sorry.
it would be 1 foot
i can't see the model.
no, it's not evenly divided.
d=3.42. divide 17.1 by 5
12h=120-36
-5x 1 x 11 x 4 i couldn't tell which was an x and when it was multiplication
pemds. do parenthesis then exponents, continue to multiplication and division from left to right, finally go to addition and subtraction from left to right.
it will be positive.
x=15
i could have gotten a few wrong but i tried. hope this helps.
