2 answers:

8 0

You just have to substitute "x" by 3.

y = 12*3
y = 36

In short the answer would be : B. 36.

Hope this helps !

y = 12x
Substitute 3 for x
y = 12(3)
Multiply
Final Answer: B.) y=36

2x-y=3; x=2 how do I solve this

2x-y=3

use the substitution method

2(2)-y= 3

4-y= 3

move 4 to the other side

sign changes from +4 to -4

4-4-y= 3-4

-y= 3-4

-y=-1

mutiply both sides by -1 to get +y

(-1)(-y)= (-1)(-1)

y= (-1)(-1)

Answer: y= 1

A circle has a diameter of

nignag [31]

Answer:

Circumference = 50.24 units

Area = 200.96 units²

Determining the area of the circle:

The formula of finding the area of the circle is π(r)² or π(d/2)².

(Where "r" represents the radius and "d" represents the diameter)

In this case, we are given the diameter. Thus, we will use the formula π(d/2)². Simply substitute the diameter in the formula to determine the area of the circle.

⇒ π(D/2)² = Area of circle

⇒ π(16/2)² = Area of circle

⇒ π(8)² = Area of circle

⇒ π × 64 = Area of circle

[Exact form of pie: 22/7; Approx form of pie: 3.14]

⇒ Area of circle ≈ 3.14 × 64

⇒ Area of circle ≈ 200.96 units²

Determining the circumference of the circle:

The formula of finding the circumference of a circle is 2πr or πd.

(Where "r" is radius and "d" is diameter)

In this case, we are given the diameter. Thus, we will use the formula πd. Simply substitute the diameter in the formula to determine the circumference of the circle.

⇒ πd = Circumference of circle

⇒ π(16) = Circumference of circle

[Exact form of pie: 22/7; Approx form of pie: 3.14]

⇒ (3.14)(16) ≈ Circumference of circle

⇒ 50.24 units ≈ Circumference of circle
