Answer:
Step-by-step explanation:
The goal to solving any equation is to have x = {something}. That means we need to get the x out from underneath that radical. It's a square root, so we can "undo" it by squaring. Square both sides because this is an equation. Squaring both sides gives you
Get everything on one side of the equals sign and set the quadratic equal to 0:
Throw this into the quadratic formula to get that the solutions are x = 5 and -8. We need to see if only one works, both work, or neither work in the original equation.
Does 
?
and
and 5 = 5. So 5 works. Let's try -8 now:
and
so
-8 = 8? No it doesn't. So only 5 works. Your choice is the third one down.
Answer:
2 cherries to 9 ice cream
Step-by-step explanation:
Treat as an equality, except flip the sign direction when yo multiply or divide both sides by a negative number
first distribute
2(4+2x)<u>></u>5x+5
distribute
8+4x<u>></u>5x+5
minus 4x fro both sides
8<u>></u>x+5
minus 5 from both sides
3<u>></u>x
x<u><</u>3
x is less than or equal to 3
Answer:
9 and 4/5
Step-by-step explanation:
Answer:
1.214 or 
or 
Step-by-step explanation:
To solve this equation, first you need to the variable term isolated. You do this by adding 10 to each side. Your equation will now look like
17c = 14
Next, you will divide both sides by the 17.
Your equation now is solved, and above, I put ther three different forms for your answer: decimal, mixed number, and improper fraction.
