Answer:
x = 4
Step-by-step explanation:
3x -5 = -2 + 9
-2 + 9 = 7 so now its 3x - 5 = 7
add 5 to the -5 so it cancels itself out. then add the 5 to 7 so it become 12. the you have 3x = 12
divide 12 ÷ 3 = 4
x = 4
Answer:
A
D
Step-by-step explanation:
The domain of the function is \[A \ge0\] If A is negative we get an imaginary number for the radius. This makes sense because the area of a circle cannot be negative.
When an answer to a question uses the greater than symbol, that means any number above the number used is a possible answer to the equation. However, when it's just a simple "x = 2", then 2 is the only possible answer to that equation. Think about it as if it were on a graph. In the attached file I have a graph that is displaying the equation "x > 4". The entire shaded area to the right of 4 could be a possible answer.
Hope this helps.
Hi!
You can turn the decimals into percentages by multiplying the decimal by 100. Multiplying a decimal by 100 turns the decimal into a percentage. So for 0.18, we would do this:

This would give us the percentage, which would be 18%.
We would do the same for 0.7, which would look like this:

Which would give us our percentage, which would be 70%.
On conclusion, the formula for turning a decimal into a percentage is:

Hope this helps! Good luck!
