x is -3 in all values so we just write an equation.
Answer:2 pizzas
Step-by-step explanation:
2 2/3 and 2 5/6 can both be rounded to 3. Double that and you get 6. Since there were 8 pizzas originally,subtract 6 from 8 to get 2 remaining pizzas.
The answers you could use are both the second and the forth. But mostly the fourth.
According to my calculations the 30% of 570 is 171
10% of 570 is 57
times that by 3 and you get 171
So let's start out by labeling Ethan as X
Since 85 is 1/3 of what Ethan drove, that means Ethan drove 3 times of 85.
85= (3x) -21
85 -21 = 3x
60=3x
20 = x
