Answer:

So x = 20

Step-by-step explanation:

AB + BC = AC sum of a segment is sum of its pieces

AB + AB = AC B is the midpoint, so AB = BC

2x + 2x = 3x + 20 putting in for AB (twice!) and AC

4x = 3x + 20 collect like terms

x = 20 subtract 3x on both sides.

Answer: A = $4,830.00

(I = A - P = $2,530.00)

Step-by-step explanation:

Equation:

A = P(1 + rt)

Calculation:

First, converting R percent to r a decimal

r = R/100 = 5.5%/100 = 0.055 per year.

Solving our equation:

A = 2300(1 + (0.055 × 20)) = 4830

A = $4,830.00

The total amount accrued, principal plus interest, from simple interest on a principal of $2,300.00 at a rate of 5.5% per year for 20 years is $4,830.00.

Help me pls thank u very much very much

Answer:

y = 95° and x = 21°

Step-by-step explanation:

y + 85° = 180° { being co-interior angles }

y = 180° - 85°

y = 95°

y = 4x + 11°[ being vertically opposite angles ]

95° = 4x + 11°

4x = 95° - 11°

4x = 84°

x = 84° / 4

x = 21°
