Answer:
2. -(-73) is positive
Step-by-step explanation:
It's not too difficult, but you can get wrapped around the axle. Here are the rules:
- the opposite of a positive number is a negative number
- the opposite of a negative number is a positive number
That is, turning a number to its opposite is just changing its sign.
__
If you layer these rules, you find ...
the opposite of (<em>the opposite of a positive number</em>) is a positive number
The first rule tells you <em>the statement in parentheses is a negative number</em>, and the second rule tell you its opposite is a positive number.
That is, a double opposite gets you back where you started. In short, <em>any even number of minus signs cancel each other</em>.
__
The numbers you have listed here* are ...
- -730 (negative)
- -(-73) = 73 (positive)
- -75 (negative)
- -(-(-701)) = -701 (negative)

Answer:
-Noah could buy 10 tacos for $15.
-Jada's tacos were not the same price as Noah's tacos.
Step-by-step explanation:
You can use a rule of three to find the amount of tacos that Noah could buy with $15:
$6 → 4
$15 → x
x=(15*4)/6=10
At this rate, Noah could buy 10 tacos for $15.
Now, to find out if Jada's tacos were the same price as Noah's tacos, you have to find the price per taco in each case by dividing the amount paid by the number of tacos bought:
Noah: 15/10=1.5
Jada: 72/50=1.44
According to this, Jada's tacos were not the same price as Noah's tacos.
