Step-by-step explanation:
An equilateral triangle has all its sides to be equal..
so.

Answer:
Yes and she would have $2 left over because all the food costs $91.
Step-by-step explanation:
We should set up an equation so that everything makes sense. A calculator would be wise for this problem, but I am going to lay it out anyhow.
We should convert the mixed numbers to improper fractions to not be confused. 3 1/2 becomes 7/2 or 3.5 and 2 1/3 becomes 7/3.
From your wording, we can assume that the money Mrs. Donnelly has is either greater than or equal to $93.
Thus, we have 12*(7/3) + 18*(7/3) is equal to or greater than 93 (this is an inequality).
The math shows that the food costed 91 and so she only has $2 left.
If x=-5 (-5)2+2=27
likewise put -4 -3 -2 -1 0 1 2 3
and in another equation also.
You can't really tell anything without the picture of the graph its self
Во-первых, вы должны умножить 3 и 30. Это дает 90. Затем умножить 5 и 30. Это дает 150. Наконец, сложите вместе, чтобы получить 240. 240 туристов.
Извините, если это плохо, я использовал переводчик, я говорю по-английски.
