I did the quiz and got it correct :)
Answer:
8b+7p=20
p = 2b
Step-by-step explanation:
Given that there is a constant speed of 8 km per hour and the number of hours be b so here 8b signifies the distance
Now on the other hand there is a constant speed of 7 km per hour and the number of hours be p so here 7p signfies the distance
So the total distance would be
= 8b + 7p
And, the total km is 20
Now the whole equation would be
8b + 7p = 20
Also it is mentoined that for getting into the park it is twice for getting into the beach
So, it would be
p = 2b
Therefore the system of equations are as follows
8b+7p=20
p = 2b
Steps to solve:
4 - 3x = 2(x - 3)
~Distribute
4 - 3x = (2 * x) + (2 * -3)
~Simplify
4 - 3x = 2x - 6
~Subtract 4 to both sides
4 - 4 - 3x = 2x - 6 - 4
~Simplify
-3x = 2x - 10
~Subtract 2x to both sides
-3x - 2x = 2x - 2x - 10
~Siimplfy
-5x = -10
~Divide -5 to both sides
-5x/-5 = -10/-5
~Simplify
x = 2
Best of Luck!
