Complimentary angles add to equal 90°. Write two equations to solve for two variable.
J + K = 90
J = K - 18

use substitution or elimination to solve
I will use substitution. substitute (K - 18) for J in the first equation to combine equations into one in only variable K.

(K - 18) + K = 90
2K - 18 = 90
2K = 90 + 18
2K = 108
K = 108/2
K = 54°

J and K are complimentary.
J + 54° = 90°
J = 36°

Solve the formula Ax+By = C for A.

jok3333 [9.3K]

Answer:

$A = \frac{C - By}{x}$

Step-by-step explanation:

Given

$Ax + By = C$

Required

Solve for A

The question implies that we make A the subject of the formula.

Start by subtracting By from both sides of the equation by x

$Ax + By - By= C - By$

$Ax = C - By$

Divide both sides by x

$\frac{Ax}{x} = \frac{C - By}{x}$

$A = \frac{C - By}{x}$

6x^2 - 9x + 3<br> - (8x²+ 7x - 1)

Solnce55 [7]

Answer:

-2x² - 16x + 4

Step-by-step explanation:

Step 1: Write out expression

6x² - 9x + 3 - (8x² + 7x - 1)

Step 2: Distribute negative

6x² - 9x + 3 - 8x² - 7x + 1

Step 3: Combine like terms (x²)

-2x² - 9x + 3 - 7x + 1

Step 4: Combine like terms (x)

-2x² - 16x + 3 + 1

Step 5: Combine like terms (constants)

-2x² - 16x + 4

Goshia [24]

ANSWER

$10.18$

EXPLANATION

We want to approximate, using the ALEKS calculator, the value of:

$\sqrt[]{103.7}$

To do this, we input the radical and the number into the calculator. The result is:

$10.18331969$

Since we have to round the answer to the nearest hundredth, we will pick the number in the thousandths place value, which is 3.

This number is less than 5, so, we round it down to 0 and add it to the number in the hundredth place value, which is 8.

Hence, the answer is:

$10.18$
