Answer: 4
Step-by-step explanation:
The procedure is pretty basic. First you have to substitute what you know in the equation. So as you know f(x)=18, just substitute f(x) by 18, leaving it like 18 = 3x + 6.
Then you have to start to move things around. First start with the + 6 that is adding, so it moves to the other side as a substraction giving 18 - 6 = 3x -> 12 = 3x. The next step is to get rid of that 3, so because it's multiplying the x, it moves to the other side as a division leaving you with 12 ÷ 3 = x -> 4 = x. There you have the answer! For a value/y of 18 in that function, the x is 4
First, distribute the -3(-2x + 1).
-3 x -2x = 6x -3 x 1 = -3 -3(-2x + 1) = 6x - 3
Now we have:
9 - 5 1/2x + 6x - 3
Combine like terms.
-5 1/2x + 6x = 1/2x 9 - 3 = 6
The two terms we are left with are 1/2x and 6.
The simplified version of this expression is 1/2x + 6.
Hope this helps!
a? I'm unsure abt this one
9/12=1/2+1/4 hope this helps
1sqmeter=100x100=100000sqcm
in 1sqcm there are 23/100=.23 grass plants
Therefore, there will be .23x100000=2300 grass plants in a sq.meter
