Answer:
D x=16
Step-by-step explanation:
75*1/3=25
so
48*1/3=16
Copy and paste it! The key is multiply!
I’ll say C because they’re the same terms as in In so
In 7 + In 5 would be In 12
You only add 7 and 5 which 12 so that’s where the 12 comes from
Hope that helped :)
Plug in 3 for "y":
7x + 2y = 48
7x + 2(3) = 48
2*3 = 6
7x + 6 = 48
Then, you have to subtract 6 to both sides..
7x = 42
Divide 7 to both sides and the your answer would be 6
You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.
90/60 = 1.5
90 minutes = 1.5 hours
speed = distance/time = (105 miles)/(1.5 hours) = 70 mph
