Mathematics
1 answer:
exis [7]4 years ago
5 0

Answer:

Angle A + Angle B + Angle C = 180° (LP)

3x+5 + 5x-18 + 7x-2 = 180

3x +5x + 7x = 180 +15

15x = 195

x=195/15

x=13

Angle A: 3x + 5 = 3 x 13 + 5 = 44

Angle B: 5x - 18 = 5 x 13 - 18 = 47

Angle C: 7x - 2 = 7 x 13 - 2 = 89

If a hexagon is worth 5 and a triangle is worth 3, what is a circle
Olegator [25]

Answer:

6

Step-by-step explanation:

Call pentagon p, circle c and triangle t

We have 2c + 2p = 2p + 2t + c

p = 5, t = 3 so

2c + 2(5) = 2(5) + 2(3) + c

2c + 10 = 10 + 6 + c

2c = 6 + c

c = 6

Martha has $10,000 saved and wants to attend a college with a current tuition of $10,000 a year. She will graduate from high sch
galben [10]

Answer:

$1,592.74

Martha will need to pay $1,592.74 more

Step-by-step explanation:

Using the compound interest/inflation formula;

A = P(1+r)^(t)

Where;

A = final value

P = initial value = $10,000

r = inflation rate = 3% = 0.03

t = time = 5 years

Substituting the values;

A = $10,000(1+0.03)^(5)

A = $11592.740743

A = $11,592.74

How much more will Martha need to save;

C = final value - initial value = A - P

C = $11,592.74 - $10,000

C = $1,592.74

Martha will need to pay $1,592.74 more
