answer will be -24

A=-24

Answer:

A = 36

Step-by-step explanation:

Using the cofunction identity

tan(90 - x) = cotx

Given

tan2A = cot(A - 18) , then

90 - 2A = A - 18 ( add 2A to both sides )

90 = 3A - 18 ( add 18 to both sides )

108 = 3A ( divide both sides by 3 )

36 = A

Answer:

yearly cost for housing expenses = $11,400, average monthly cost for food = $650

yearly clothing cost = $900,

average monthly cost for transportation= $500,

Yearly cost for insurance & medical= $14,400

yearly cost for emergency fund = $600

average monthly college saving = $50

Step-by-step explanation:

Yearly housing = monthly cost * 12 = 950 * 12 = 11400

Food, monthly = 7800 /12 = 650

Clothing, yearly = 75 * 12 = $900

Monthly transport = 6000 / 12 = $500

Insurance and medical = 1200*12 =14400

Emergency fund = $50 * 12 = $600

College saving = $600 / 12 = $50

Answer:

b = -0.79

Step-by-step explanation:

b+ 2.77 over -2 = -1.78

multiply -2 on both sides to get

b + 2.77 = -3.56

subtract 2.77 on both sides to get

b = -0.79

I'm not sure as I didn't work it out too well but I hope you got the idea

Answer:

15.7 percent of 80 = 12.56

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 80.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$80=100\%$

Step 4: Similarly, $x=15.7\%$.

Step 5: This results in a pair of simple equations:

$80=100\%(1)$.

$x=15.7\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{80}{x}=\frac{100\%}{15.7\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{80}=\frac{15.7}{100}$

$\Rightarrow x=12.56$

Therefore, $15.7\%$ of $80$ is $12.56$

Answer:

x = -2

Step-by-step explanation:

2 (x - 1) = 4x + 3

use the distributive property

2x - 2 = 4x + 3

    +2          +2

2x = 4x + 5

-4x  -4x      

-2x = 5

divide by -2

x = - 5/2

Answer: I need more evindence to answered it but I say its the third one

Step-by-step explanation:

Answer:

Step-by-step explanation:

So 750 and 48.75

so tax is a percent of the whole or 750

750=100%

48.75=x%

750/100=48.75/x

solve for x

multiply both sides by x

750x/100=48.75

multiply both sides by 100

750x=4875

divide both sides by 750

x=6.5

the asnwe ris 6.5%

Answer:

  x = 2, y = 10, sides = 15

Step-by-step explanation:

The hash marks tell you all of the sides are the same length. You can use this fact to relate the side length expressions to each other to solve for the variables.

We see that x appears in the left and right expressions only. So we can find x by setting those expressions equal to each other.

  8x -1 = 4x +7

  4x = 8 . . . . . . . . . . . . . add 1-4x to both sides of the equation

  x = 2 . . . . . . . . . . . . . . divide by 4; the value of x

  8x -1 = 8(2) -1 = 15 . . . the length of the sides

Now, we can find y using an expression that involves y. The top expression is the simplest:

  y +5 = 15 . . . . . the length of the side we just found

  y = 10 . . . . . . . subtract 5

The variable values are ...

  x = 2

  y = 10

The side lengths are 15.
