12.5 or $12\frac{1}{2}$

Step-by-step explanation:

You have to isolate the a variable, and to do that you have to divide by 2/5 on both sides.

$\frac{2}{5} a=5\\\\a=5/\frac{2}{5} \\$

simplify.

$a=12\frac{1}{2}$

The answer to your question is a simplification of the equation presented.

$\frac{2}{5}$ * $\frac{a}{1}$ = $\frac{2a}{5}$

5 = 2/5(a) can be re written as 2a/5

Or, When solving for a, 2/5(12.5) = 5, meaning A = 12.5

-4(x+3) = y - 1

Step-by-step explanation:

Given

Slope of line = -4

Point = (-3,1)

Required

Point slope equation of line

To get the equation of line, we make use of the following slope formula

$m = \frac{y - y_1}{x - x_1}$

Where m = -4 and (x_1,y_1) = (-3,1)

So; $m = \frac{y - y_1}{x - x_1}$ becomes

$-4 = \frac{y - 1}{x - (-3)}$

$-4 = \frac{y - 1}{x +3}$

Multiply both sides by x + 3

$-4(x+3) = \frac{y - 1}{x +3} * (x+3)$

-4(x+3) = y - 1

Hence, the point slope form of the line is -4(x+3) = y - 1
