Answer:

$x=11$

Step-by-step explanation:

Angle EFB = 180 - 147 = 33 (Angles on a straight line add up to 180 degrees)

Angle FEB = 180 - 4x (Angles on a straight line add up to 180 degrees)

Since the angles in a triangle add up to 180 degrees ,

$33+(180-4x)+x=180$

Remove brackets:

$33+180-4x+x=180$

Add/Subtract:

$213-3x=180$

Subtract 213 from both sides:

$213-3x-213=180-213$

$-3x=-33$

Divide both sides by -3:

$\frac{-3x}{-3}=\frac{-33}{-3}$

$x=11$

Solve the system of equations by using substitution.

Nat2105 [25]

Answer:

(x, y) = (-1, 1)

Step-by-step explanation:

$y = 2x +3 ----(1) \\\\y = x + 2 ----(2)\\\\substitute \ (2) \ in \ (1) : x + 2 = 2x + 3$

$x - 2x = 3 - 2\\\\-x = 1\\\\x = -1\\\\Substitute \ x = -1 \ in \ (2) : y = -1 + 2 => y = 1$

Nancy wants to receive the most return on a $50,000 investment. She has two options. Option 1 gives annual interest at 5% compou

Annette [7]

Answer:

Option 1 earns more interest by $2396.13

Step-by-step explanation:

Step 1: Determine the prices

50000(1 + 0.05)^3 = 57881.30

50000(1 + 0.0035/12)^36 = 55527

Step 2: Determine which pays higher

Step 3: Find difference

57881.30 - 55527 = 2396.13

And we have our final answer!
