Consider the equation v + 4 + v = 8. What is the resulting equation after the first step in the solution?

1 answer:

4 0

The resulting equation after the first step in the solution of the starting equation v + 4 + v = 8 is 2v + 4 = 8. So, we have the equation v + 4 + v = 8. We can group similar terms on the left side: (v + v) + 4 = 8. When we sum these two in the parenthesis, we will get the resulting equation which is: 2v + 4 = 8.

What is the answer to 14 + x = 46;x= 32

Liono4ka [1.6K]

Simplifying 14 + x = 46
Solving 14 + x = 46 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-14' to each side of the equation. 14 + -14 + x = 46 + -14 Combine like terms: 14 + -14 = 0 0 + x = 46 + -14 x = 46 + -14 Combine like terms: 46 + -14 = 32 x = 32 Simplifying x = 32

Find the length of AC. Express your answer in terms of pi. Answer options: 5, 30, 45, 15.

Nitella [24]

Answer:

The correct answer is 3πcm

Step-by-step explanation:

The length of an arc is calculated using the formula P=∅/360×2πr

where ∅is the angle the arc subtends at the center of the circle, and r is the radius of the circle of which the arc is part.

2r gives the diameter which from the diagram corresponds to AB=36 cm

therefore P=30/360×π×36

=3πcm
