Well you have to first find the constant of Brand X which would be 2.70/10 = .27. Brand Y is .4 more so that would be .31 per ounce. So then .31 x 11 = 3.41. The cost of 11 ounces of brand Y is $3.41.
Since they have the same base we can just add all the exponents
-3+ 10= 7
keep the base so the answer is
12^7
1/4, because you disregard the repeating 25s and round, and 25 x 4 is one hundred, so simplified it's 1/4.
Step-by-step explanation:
162/2 (the same as 162÷2) =83.5
83.5+83.5=162
^
that was two times to add so we know for sure that 162/2=83.5. Theres no special way to solve it since its just dived by <em>two</em>. Its just 162÷2=83.5
Hope this helps.
