Zachs car travels 21 miles per hour on 1 gallon of gas write an equation to represent the relationship between the gas zachs car uses and the deistance he trevels than solve the equation to see how far zach travels if he uses 16 gallons of gas

the car will travel 336 miles on 16 gallons of gas

Step-by-step explanation:

Gas mileage is the number of miles that Zach's car can travel per gallon of gasoline. Zachs car travels 21 miles per hour on 1 gallon of gas. This means that the mileage of the car is 21 miles per gallon

Let the distance which Zach's car travels be x miles.

An equation to represent the relationship between the gas Zach's car uses and the distance that he travels would be

x = mileage of the car × number of gallons, n

x = 21n

If it uses 16 gallons of gas, the distance travelled would be x

x = 21 × 16 = 336 miles

true

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
