Solve p=10a+3b for a

Gre4nikov [31]

Answer:

a = (p - 3b)/10

Step-by-step explanation:

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS (Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction).

p = 10a + 3b

First, subtract 3b from both sides.

p (-3b) = 10a + 3b (-3b)

p - 3b = 10a

Next, isolate the a. Divide 10 from both sides.

(p - 3b)/10 = (10a)/10

(p - 3b)/10 = a

a = (p - 3b)/10 is your answer.

mariarad [96]

Answer:

-21

Step-by-step explanation:

I assume this is a 2 by 2 matrix.

$\begin{bmatrix} -5 & 1\\1 & 4 \end{bmatrix}$

determinant = -5 * 4 - 1 * 1 = -20 - 1 = -21
