Answer:
4.5
Step-by-step explanation:
Since the slope of the equation is 40, we know that for every gallon of gas used, the car travels 40 miles. We know that in total he traveled 180 mi, so if we divide 40 into 180 we can find out how many gallons of gas he used.
180 / 40 = 4.5
so 4.5 gallons of gas were used. To check our work we can just substitute it back into the equation
40 x 4.5 = 180
This equation is true, so now we know that 4.5 gal of gas was used in total. I hope this helps you out :)
Hey there!
To start, you must use the distance formula which is .
x1 and x2 are the x coordinates of the points (it does not matter which one you assign to be x1 and x2) and y1 and y2 are the y coordinates (also does not matter which one you assign to be y1 and y2).
Now, set up your formula and simplify:
= ≈ 25.0799

Answer:
58%
Step-by-step explanation:
The first thing that you have to do if figure out how many sandwiches are left we do this by the total - bad sandwiches = good sandwiches
12-5=7
There are 7 good sandwiches left. To figure out the percentage you do = now we fill in the parts the part is 7, the total is 12 and the % is x
= now we cross multiply, 7 x 100 and 12 x X
700=12x now we divide both sides by 12 so the x is alone
x = 58.33 now we round down because it ends in.3
x=58
