Order from least to greatest 0.6 4/5 0.75
Aleonysh [2.5K]
Because the majority is in decimal form, you'll have to change the fraction to a decimal too so that it would be easier to solve this problem. 4/5 in decimal form is 0.8

So, the order from least to greatest is

0.6, 0.75, 4/5

Hope this helps :)

–0.2(x – 20) = 44 – x
GarryVolchara [31]

-0.2(x-20)=44-x\qquad\text{use distributive property}\\\\-0.2x+4=44-x\qquad\text{subtract 4 from both sides}\\\\-0.2x=40-x\qquad\text{add x to both sides}\\\\0.8x=40\qquad\text{divide both sides by 0.8}\\\\x=\dfrac{40}{0.8}\\\\x=\dfrac{400}{8}\\\\\boxed{x=50}

How many solutions are there to the equation below? |x| = -31​
ella [17]

Break down the problem into these two equations;

x = -31

-x = -31

Solve for the 1st equation; x = -31

x = -31

Solve for the 2nd equation; -x = -31

x = 31

Collect all solutions

x = ±31

Check the solution

When x = -31, the original equation; |x| = -31 does not hold true. Thus, we will drop x = -31 from the solution set.

Check the solution again;

When x = 31, the original equation |x| = -31 does not hold true as well. Thus we will drop x = 31 from the solution set.

Therefore,

<u>No solution exists to this equation. </u>
