Answer:
496.631579
Step-by-step explanation:
Make a proportion
We know that a 377.44 over a number must equal 76%
377.44/x=76/100
Cross multiply
76x=37,744
Divide by 76 on both sides
x=496.631579
So, 76% of 496.631579 is 377.44

Answer:
60.4miles/hr
Step-by-step explanation:
Given parameters:
Distance covered by the car = 145miles
Time taken = 2.4hrs
Unknown:
Average speed of the car = ?
Solution:
Average speed is the rate of change of distance with time;
Average speed = 
Input the parameters and solve;
Average speed = 
= 60.4miles/hr
Steps:
1. 6x=4y + 7
2. You have to write it in slope intercept to get the slope and y-intercept.
3. Subtract 7 on both sides
4y= 6x-7
4. Divide everything by 4
5. Y= 3/2x + -7/4
6. Slope= 3/2 y-intercept= -7/4
