Firstly, you have yo multiply out the first bracket by multiplying (2x - 5) by 4. The equation would then look like:
8x - 20 = 5x - 20 + 3x
Then you have to put normal numbers on one side and x-terms on the other. It would look like:
-20 + 20 = 5x + 3x - 8x
Then you should solve the additions and subtractions
0 = 0x
Since ANY number multiplied by 0 is zero, your equation has infinite solutions.
Answer:
The one about the beetles
Step-by-step explanation:
Best way to tell is to convert them all to either decimals, fractions, or percentages. I usually convert to decimals. So, 75% is 0.75. 0.9 is already a decimal. And 4/5 is 0.8.
So 0.75, or 75%, is now clearly the smallest. In order from least to greatest, they go 75%, 4/5, and 0.9.
<u><em>Answer:</em></u>
Elliot biked 70 miles
<u><em>Explanation:</em></u>
We are given that the total distance of the race is 100 miles
We are also given that Elliot covered 
of this distance
To get the number of miles covered by Elliot, we will simply multiply the ratio of the covered distance () by thetotal distance of the race (100 miles)
<u>This is done as follows:</u>
Distance covered = 
miles
<u>Therefore,</u> Elliot biked for 70 miles
Hope this helps :)
