Answers: Choice A, choice B, and choice C

Those two values, when multiplied by the given value, will lead to a rational number. If you pick choice A, then you get 7 as a result after multiplying. If you choose choice B, then you get -7

Note that
7 = 7/1
-7 = -7/1
So 7 and -7 are rational

Also, when multiplying 0 by any number, the result is always 0. The rule is 0*x = x*0 = 0
The value 0 is rational as 0 = 0/1

The only non-answer is choice D as 7*sqrt(7) can't be expressed as a ratio of two whole numbers.

Suppose a medium pizza at Vincent’s costs $6.75 plus $0.75 for each topping, and the cost of a medium pizza at Original Italian
lapo4ka [179]

Answer:

12 toppings

Step-by-step explanation:

There's a 60 cent difference in the base price, and the price of toppings is a 5 cent difference, so it would take 60/5 or 12 toppings to make up the difference.   r, you can make a chart.  Or you can do algebra and solve an equation:

6.75 + .75 x = 6.15 + .8x  where x is the number of toppings.  Subtract 6.15 from both sides.

.60 + .75x = .8 x     Subtract .75x from both sides

.60 = .05x         Divide both sides by .05
