Arrange from least to greatest, 4.3, 5.5, 6 1/6, 15/4, 4 3/8?

Sophie [7]

Here are the numbers
4.3 , 5.5 , 6 $\frac{1}{6}$ , $\frac{15}{4}$ , 4 $\frac{3}{8}$
I'm going to change them into fractions
In the fractions, divide the numerator by the denominator
$6\frac{1}{6}$ <em />⇔6.1666---
$\frac{15}{4}$ ⇔3.75
$4 \frac{3}{8}$ ⇔4.375
Now to arrange them from least to the greatest
$\frac{15}{4}$ , 4.3 , $4 \frac{3}{8}$ , 5.5 , $6\frac{1}{6}$

What is the value of x in the equation 3x - 4 (2x - 5) = 15

Zepler [3.9K]

Hey there! I'm happy to help!

Here is our equation

3x - 4 (2x - 5) = 15

First, we will sue the distributive property to remove the parentheses. The term outside the parentheses is -4, so that is what we multiply the insides by.

3x-8x+20=15

We combine our like terms (our x-values).

-5x+20=15

We subtract 20 from both sides.

-5x=-5

We divide both sides by -5.

x=1

Have a wonderful day and keep on learning! :D
