Answer:

707 feet above sea level

Step-by-step explanation:

2 hours and 25 minutes is about 2.4167 hours.

Therefore:

y=8.77x+686

y=8.77(2.4167)+686

y=21.1944+686

y=707.1944

So the hiker's elevation will be approximately 707 feet above sea level

Hey!

---------------------------------------------

Solution:

Find the Highest Common Factor of 8, 12, and 20.

Highest Common Factor = 4

Divide.

8 / 4 = 2

12 / 4 = 3

20 / 4 = 5

4 symbolizes the amount of baskets there are.

---------------------------------------------

Answer:

2 banana's per basket.

3 apple's per basket.

5 orange's per basket.

---------------------------------------------

There is no possible way that there can be the same amount of fruit in each basket.

X°+(x+30)=180°<br>I need answer​
djyliett [7]

Answer:

210 + -1x

Step-by-step explanation:

Simplifying

X + (x + -30) = 180

Reorder the terms:

X + (-30 + x) = 180

Remove parenthesis around (-30 + x)

X + -30 + x = 180

Reorder the terms:

-30 + X + x = 180

Solving

-30 + X + x = 180

Solving for variable 'X'.

Move all terms containing X to the left, all other terms to the right.

Add '30' to each side of the equation.

-30 + X + 30 + x = 180 + 30

Reorder the terms:

-30 + 30 + X + x = 180 + 30

Combine like terms: -30 + 30 = 0

0 + X + x = 180 + 30

X + x = 180 + 30

Combine like terms: 180 + 30 = 210

X + x = 210

Add '-1x' to each side of the equation.

X + x + -1x = 210 + -1x

Combine like terms: x + -1x = 0

X + 0 = 210 + -1x

X = 210 + -1x

Simplifying

X = 210 + -1x
