∠e and ∠f are vertical angles with m∠e=5x+10 and m∠f=7x−12 . what is the value of x?

 11

Step-by-step explanation:

We are given that ∠E and ∠F are vertical angles with m∠E=5x+10 and m∠F=7x−12 .

We know that vertical angles are congruent, then their measures must be equal.

i.e. if ∠E and ∠F are vertical angles.

⇒ m∠E=m∠F

  [Substitute the measures of ∠E and ∠F]

Subtract 5x from both sides , we get

Add 12 on both sides , we get

Divide both sides by 2 , we get

or x=11

Hence, the value of x= 11

$9.89

step-by-step explanation:

9.90 = p x .06 x .25 (3/12 changed to a decimal)

9.90 = p x 0.015

9.90 - 0.015 = p

9.89 = p

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
