Recognize the difference of 2 perfect squares
remember that
a²-b²=(a-b)(a+b)
so
9=3²
y²=y²

9-y²=
3²-y²=
(3-y)(3+y)

Kevin hiked up lambs Canyon and two hours and then ran back down in one hour has been running downhill was 2.8 mph greater than
coldgirl [10]

Answer: he hiked 5.6 miles up the canyon.

Step-by-step explanation:

Let x represent his speed hiking uphill.

His speed running downhill was 2.8 mph greater than his speed hiking uphill. This means that his speed running downhill would be x + 2.8

Distance = speed × time

Kevin hiked up Lamb’s Canyon in 2 hours. This means that the distance covered by hiking uphill is 2 × x = 2x

He ran back downhill in 1 hour. This means that the distance covered by running downhill is 1 × (x + 2.8) =

x + 2.8

Since the distance uphill is the same as the distance downhill, then

2x = x + 2.8

2x - x = 2.8

x = 2.8

Therefore, the distance hiked up the canyon is

2x = 2 × 2.8 = 5.6 miles

Match the equation with the step needed to solve it.
ziro4ka [17]

To solve this, you need to isolate/get the variable "m" by itself in the equation:

1. 2m - 1 = 3m    Subtract 2m on both sides to get "m" on one side of the equation

2m - 2m - 1 = 3m - 2m

-1 = m

2. 2m = 1 + m     Subtract m on both sides to get "m" on one side of the equation

2m - m = 1 + m - m

m = 1

3. m - 1 = 2       Add 1 on both sides to get "m" by itself

m - 1 + 1 = 2 + 1

m = 3

4. 2 + m = 3   Subtract 2 on both sides to get "m" by itself

m = 1

5. -2 + m = 1      Add 2 on both sides to get "m" by itself

m = 3

6. 3 = 1 + m     Subtract 1 on both sides to get "m" by itself

2 = m
