Answer:

x = 55 or x = 15

Step-by-step explanation:

Solve Absolute Value.

We know that either 1/5x - 7 = 4 or 1/5x - 7 = -4.

1/5x - 7 = 4

1/5x - 7 + 7 = 4 + 7

1/5x = 11

1/5x (5) = 11 (5)

x = 55 (one possibility)

1/5x - 7 = -4

1/5x - 7 + 7 = -4 + 7

1/5x = 3

1/5x (5) = 3 (5)

x = 15 (second possibility)

the sides of a square are five to the power of two fifths inches long. what is the area of the square? five to the power of four

mario62 [17]

The area of a square is given by;
Area= $side^{2}$
Area= $5^{ \frac{2}{5} } * 5^{ \frac{2}{5} }$
Basing on the law of indices;
$a^{m} + a^{n}$ = $a^{m+n}$
so,
$5^{ \frac{2}{5} } * 5^{ \frac{2}{5} } = 5^{ \frac{2}{5}+ \frac{2}{5} } = 5^{ \frac{4}{5} } square inches$

Answer:

$x=\frac{-1}{6}$

Step-by-step explanation:

$9(x+1) -4x = 5-(x-3)$

$9(x+1) -4x = 5-(x-3) \\$

$9x+9\cdot1-4x=5-\left(x-3\right)$

$9x+9-4x=5-\left(x-3\right)$

$\left(9x-4x\right)+9=5-\left(x-3\right)$

$5x+9=5-\left(x-3\right)$

$5x+9=5-x+3$

$5x+9=-x+\left(5+3\right)$

$5x+9=-x+8$

$5x+9=-x+8$

$5x+9+x=-x+8+x$

$5x+x+9=-x+8+x$

$6x+9=-x+8+x$

$6x+9=-x+x+8$

$6x+9=8$

$6x+9=8$

$6x+9-9=8-9$

$6x=8-9$

$6x=-1$

$\frac{6x}{6}=\frac{-1}{6}$

$x=\frac{-1}{6}$
