Answer:
45%
Step-by-step explanation:
Create a fraction with the of " something " on the denominator and multiply by 100% to create the percentage, that is
percent =
× 100% = 45%
An expression is a mat scentence but not a complet on.Example:2x3. Or a x 5. I hope I said it clearly for you.
Please graph the triangle using the info in the description provided. The answer to this question will likely become self-evident if your drawing is correct. Remember, the sum of the 3 interior angles of any triangle is always 180 degrees.
For get the solution of this task, we must make the system of equations.First it: "The quotient between the sum of two numbers and one of them is equal to 3" Let's take two values: a and b.(a+b)/b=3 --- it's will be first equation in our system.
and "The inverse of double the sum of them and equal to 1/6"1/2(a+b)=1/6 it's will be second equation in our system.
Attention at parenthesis.
System(a+b)/b=31/2(a+b)=1/6
by the first equation:(a+b)/b=3a+b=3ba=2b --- we will use this equation for second equation in system
1/2(2b+b)=1/61/3b)=1/63b=6b=2 and a=2b, that's mean a=1.The answer is pair (1;2)
