Sorry, I thought you meant what 1 minus three is, not questions 1 through three
6.20÷4 = 1.55
price per individual dounut =$1.55
1.55×12=18.6
12 donuts =$18.6
The answer is 3x-12y because you combine the like terms so 2x+x=3x and -8y-4y=-12y
Answer:
B
Step-by-step explanation:
To multiply scientific notation, multiply each part of the number.
(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12
Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.
The solution is B.
