Answer:
Step-by-step explanation:
We have been given the equation
Take square root both sides. When ever we take square root, we include plus minus sign
Now, subtract 6 to both sides of the equation
Divide both sides by 5
In decimal we have
Answer:
32.5
Step-by-step explanation:
% over 100 = is/ of
50% over 100 = x / 65
cross multiply
3250/ 100x = 32.5
The unit rate of speed is 52.5 miles per hour
<em><u>Solution:</u></em>
Given that On a trip to visit relatives you drive 1,115.625 miles over the course of 21 hours and 15 minutes
We know that, 1 hour = 60 minutes
21 hours and 15 minutes = 21 hours + (15/60) hours = 21 + 0.25 = 21.25 hours
So they drive 1115.625 miles in 21.25 hours
To find the unit rate of speed of your vehicle in miles per hour, divide the total miles by time taken
unit rate of speed means miles driven in 1 hour
So the unit rate of speed is 52.5 miles per hour
4x + 9 = 68
Subtract 9 from both sides:
4x = 59
Divide both sides by 4
X = 59/4
X = 14.75
