5y - 16 + 3y + 20 = 180 degrees

Combine like terms on the left side

8y + 4 = 180

Subtract 4 from both sides.

8y = 176

Divide both sides by 8

y = 22

Plug 22 into y for each angle.

3y + 20 = 3(22) + 20 = 66 + 20 = 86 degrees

5y - 16 = 5(22) - 16 = 110 - 16 = 94

The angle opposite 5y - 16 also equals 94 because they are vertical angles.

The angle opposite of 3y + 20 also equals 86 because they are vertical angles

Simplify.

Kazeer [188]

(1/2)^2 = 1/4
2-2/3 = 6/3 - 2/3 = 4/3

OK so:
(1/2)^2 - 6(2-2/3) = 1/4 - 6(4/3)
= 1/4 - 8
= 1/4 - 32/4
= -31/4

Y-4x=3. 2x-3y=21 can someone help

mars1129 [50]

Y-4X =3 ; 2x-3y=21

Y= 3+ 4x

2x -3( 3+4x)= 21

2x- 9- 12x= 21

-10x -9= 21

-10x -9+9= 21+9

-10x = 30

X= 30/-10= -3

Y= 3+4x = 3+ 4* (-3)= 3-12= -9

An initial investment of $100,000 at 12% interest is compounded weekly (use 52 weeks in a year). What will the investment be wor

ozzi

Answer:

$3644675.9

Step-by-step explanation:

The initial investment is $100000. The interest rate is 12%.

We are asked to determine the final amount the investment will become after 30 years if the interest is compounded weekly.

The weekly interest rate is $\frac{12}{52} = 0.231$ %.

Assuming 1 year equivalent to 52 weeks.

Hence, using the formula of compound interest the final sum will be

$100000(1 + \frac{0.231}{100} )^{(30 \times 52)}$

= $3644675.9 (Approximate)

4x + 1/2 (8x + 6) = 2(4x + 3)

inysia [295]

Answer:

No solution 0≠3

Step-by-step explanation:

simplify parenthesis:

4x+4x+3=8x+6

combine like terms:

8x+3=8x+6

subtract three from both sides

8x=8x+3

subtract 8x from both sides

0≠3

This equation has no solution
