Step-by-step explanation:
Answer:
20
Step-by-step explanation:
3/4 = 75%
15 ÷ 75% = 20
15 is 75% of 20.
The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.
If you were to solve the equation it would look like this:
2x+6=3x-8
-3x -3x
-x+6=-8
-6 -6
-x=-14
/-1 /-1
x=14
4x²-5=3x+4
4x²-3x-9=0
x=(3±√((-3)²-4*4*-9))/2*4
x=3±√(9+144) /8
x=(3±√153) /8
x=⅜±√153/8
Sid walked 6 miles, which is 3/5 of the total distance.
Divide 6 with 3
6/3 = 2
2 miles is the walking distance for 1/5
Multiply 5 to both sides
2 (x 5) = 1/5 (x 5)
10 = 1
The total distance is 10 miles
hope this helps
