F is directly proportional to A. if F=72 when A=9 find F when A=7

Answers

Answer 1
56 is your answer.

Equation for direct proportion is y = kx where k is the constant of proportionality. For your letters, it’s f = ka

We know 72 =k9, so k = 8
Then they want you to solve
f = 8•7
f = 56

6(x-1)=9(x+2) what equal what answer

Answers

Answer:

well x = -8 so

Let's solve your equation step-by-step.

6(x−1)=9(x+2)

(6)(x)+(6)(−1)=(9)(x)+(9)(2)

6x+−6=9x+18

6x−6=9x+18

step two

6x−6−9x=9x+18−9x

−3x−6=18

step three

−3x−6+6=18+6

−3x=24

last step

−3x /−3 = -24 /−3

x=−8

Find the measure of angle F

Answers

Answer:

∠ F = 80°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the interior angles and equate to 720

7x + 7x + 4x + 7x + 7x + 4x = 720

36x = 720 ( divide both sides by 36 )

x = 20

Then

∠ F = 4x = 4 × 20° = 80°
