A and B are complementary angles. If A = (x – 23)° and m
Lana71 [14]

Answer:

∠ B = 85°

Step-by-step explanation:

Complementary angles sum to 90° , then

x - 23 + 2x + 29 = 90 , that is

3x + 6 = 90 ( subtract 6 from both sides )

3x = 84 ( divide both sides by 3 )

x = 28

Then

∠ B = 2x + 29 = 2(28) + 29 = 56 + 29 = 85°

ANTONII [103]

Answer:

Step-by-step explanation:

Use Compound Intrest Formula

a = p(1 +  \frac{r}{n} ) {}^{nt}

  • where p is the original amount.
  • R is the amount of percentage compounded
  • N is amount of times compounded per year.
  • T is how long the interest last.

P is 400,00p

T is 12% or 0.12

N is 4 since it is compounded quarterly

T is 5.

Plug the values in

400000(1 +  \frac{0.12}{4} ) {}^{20}

Ypu get

$722444.49386776

????????????????????
Snowcat [4.5K]
Greetings!

Substitute:
x+y=1000 \\ x=1000-y
Now we can input this into the other equation so, we only have one variable.

Solve for y.
0.05(1000-y)+0.06y=57
Distribute the parenthesis.
50-0.05y+0.06y=57
Combine Like Terms.
50-0.01y=57
Add -50 to both sides.
(50-0.01y)+(-50)=(57)+(-50)
Simplify.
0.01y=7
Divide both sides by 0.01.
(0.01y)/0.01=(7)/0.01
Simplify.
y=700

Input this value into the other equation.
x+700=1000
Add -700 to both sides.
(x+700)+(-700)=(1000)+(-700)
Simplify.
x=300

The answer would be 300,700

Hope this helps.
