X/5 when x=30 is 30/5 which is 6
3y^2 when y=2 is 3(2)^2 which is 3(4) which is 12
And z=-2... if we plug these into the original question we get 6+12-(-2)
The negatives cancel and it becomes 6+12+2 which =20
Your answer is 20
The scale before you simplify would be 4 inches=380 miles
You then convert it into a fraction 4/380 and simplify
4/380=1/95
It would not be A, B, C, or D, the person who had created the test has made a mistake
Answer:
So a ratio of 8:3 means for every 8 cars that is 3 trucks so we have the number of trucks which is 21 so what i did to find the answer was see how many times 3 went into 21 which is 7 times then you would take the 7 and times it by 8 and get 56 so there are 56 cars.
