Ok so first you would create a proportion.
8/x=4/1. Next you cross multiply and divide,
1 • 8÷4=x. Ratios are fractions with the first number being the numerator and the second being the denominator. If you think of it this way, you just find an equivalent fraction. Your answer would be 8:2 because in your proportion x=2.
25 meters per second x 60 seconds = 1500 meters per minute
1500 meters per minute x 60 minutes per hour = 90,000 meters per hour
1 mile = 1609.34 meters
90000/1609.34 = 55.92 miles per hour
round answer to either 55.9 or 56 mph depending on what you need.
Subtract 6 from both sides
15x= 195
Divide both sides by 15
x=13
Final answer: x=13
Check:
15(13)+6
195+6
201
201=201
Hi i'd be glad to help you with this equation.
basically all we have to do is find (65%) of 455*.
65% of 455* = 295.75
Next.
455 + 295.75 = 750.75
So, to check my work I have 750.75 miles in total.
I have already driven 455 miles of 750.75 miles.
Using subtraction we subtract our distance from our total.
750.75 - 455 = 295.75
So, in total your answer to this problem is (295.75)
Hope this helps.
Have a great day!
Only b because A is correct
