Hello!
The equation that represents this situation is A. 3t = 27.
Explanation:
This is because an equation is a "mathematical sentence" and this equation says that if you multiply the costs of the three friends' tickets, the total cost would be $27.
The average speed is given by:
average speed=(total distance)/(total time)
total time for the first 30 miles was:
time=distance/speed
=30/30
=1 hr
total time for the remaining 30 miles
=30/60
=0.5
hence the average speed will be:
speed=(30+30)/(1+0.5)=60/1.5=40 miles per hour

3 2
/7
Step-by-step explanation:
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
<span>We simplify the equation to the form, which is simple to understand
<span>4x+8-2x=20
We move all terms containing x to the left and all other terms to the right.
<span>+4x-2x=+20-8
We simplify left and right side of the equation.
<span>+2x=+12
We divide both sides of the equation by 2 to get x.
