X=2. You use substitution to put the y=3x-5 into 6x+3y=15.
So you get 6x+3(3x-5)=15
=6x+9x-15=15
add 15 on both sides to get the x's alone and add the x's together.
6+9=15 -- 15+15=30
15x=30
30/15 =2
x=2
The standard form is also known as the Scientific Notation
So to find the standard form for 3.050904 we need to start counting from 4 until we reach the zero. So let's count :)
I got 6 numbers (but don't count number 3)
Now since the virgule is in front of the 6 number we will have ^-6
Like that : 3050904*10^-6
Why do we have -6 instead of 6 ? well the reason is because we're going on the left side. Because we start counting from right(4) until we reach the left side(0)
I hope that's help and please if you have any suggestion let me know :)
Answer:
3:15 or 3 to 15
Step-by-step explanation:
I hope this helps :)
The answer is A.) Length = 15, width = 9.
9x2 = 18, 18 - 3 = 15
15 x 2 = 30, 9 x 2 = 18
18 + 30 = 48.
