5 less than a number is equivalent to 1 more than three times the number. the number is

lutik1710 [3]

Answer:

x = -1

Step-by-step explanation:

5 less than a number is equivalent to 1 more than three times the number

number = x

x - 5 = 3x + 1

now im going to get the numbers and variable on different sides

x - 5 + 5 = x

3x + 1 - 3x = 1

x + 3x = 4x

1 - 5 = -4

4x = -4

lastly im going to divide each side by 4

4x / 4 = x

-4 / 4 = -1

x = -1

It turns out that (0.125)^3 can be written as 2^a for some integer a. Find a.

Ann [662]

Answer:

$a=-9$

Step-by-step explanation:

We begin with $(0.125)^3$

First, we can convert this decimal into a fraction

$(\frac{1}{8} )^3$

Now, we can simplify the denominator of the fraction

$(\frac{1}{2^{3} } )^3$

Next, we can remove the fraction by rewriting the fraction with a negative power.

$(2^{-3} )^3$

Lastly, we can remove the parenthesis by multiplying the powers together.

$2^{-9}$

This means that $a=-9$
