\frac{20 - 80}{0 - 60 }  = slope \: or the \: rate \: of \: \\  change \:  \\  \\      \frac{ - 60}{ - 60}  = 1
It tells you that over these intervals the balloon is going at a constant speed.

Please explain how to solve for x in the attached photo.
natulia [17]

Answer:

x = 24°

Step-by-step explanation:

the sum of the interior angles in a triangle = 180°

so:

(2x + 5°) + 64° + 3x - 9° = 180°

combine like terms:

5x + 60° = 180°

subtract 60° from each side of the equation:

5x = 120°

x = 24°

Which expressions are equivalent to 5p+3p+(-9)5p+3p+(−9)5, p, plus, 3, p, plus, (, minus, 9, )? Choose all answers that apply:
Lemur [1.5K]

Answer:

Option B.

Step-by-step explanation:

The given expression is

5p+3p+(-9)

We need to find an expression which is equivalent to the given expression.

Combine like terms.

(5p+3p)-9

8p-9

The simplified form of given expression is 8p-9. So, option A is incorrect.

In option B, the given expression

3(p+(-3))+5p

3(p-3)+5p

Using distributive property, we get

3p-9+5p

Combined liker terms.

(5p+3p)-9

8p-9

It is same as the simplified form of given expression.

Therefore, the expression 3(p+(-3))+5p is equivalent to the given expression and correct option is B.
