(10 + 9) x (3 - 1) x 2 = +75
19 x 2 x 2
76
76 > 75
Well do you know a common factor between 8, 5, and 12, if so it is super simple to find your answer. :)
I think its 2.8.
Reason why:
4/5 = 0.8
Then the 2 would a whole number...
so 2.8.
-10z+14 would be the simplified answer
To convert to scientific notation, start by moving the decimal place in the number until you have a coefficient between 1 and 10; here it is 3.45. The number of places to the left that you had to move the decimal point is the exponent. Here, we had to move the decimal 4 places to the right, so the exponent is -4.
