Answer:
42.5
Step-by-step explanation:
Is this from khan? Meh, anyways, we need to find the area of the missing sides first.
The formula for area of a triangle is:
1/2(b×h)
So we multiply two and two and you get four. 2×2=4
Then you divide and that would be two. 4÷2=2
For the next one, you do the same.
You multiply five and two, which gives you ten. 5×2=10
Then you divide by two, which gives you five. 10÷2=5
Then you add the missing area lengths together to get a total of seven.
Then you would find the entire area. By that, I mean the whole thing.
I'm not sure if you noticed but the height of the missing triangle on the left is two.
2+3.5=5.5.
So that means that we have found out the entire height.
5.5×9=49.5
But that's not the answer. That's because the shape most certainly not a whole shape. It has some missing parts, if you see what I mean.
So that means that you have to subtract the area missing from the total area. That would be....
49.5 - 7 = 42.5
total missing actual

Answer:
1) x=1/2-y/2-3z
2)x= 16/3- 2y/3- 5z/3
3)x= 11/7- 3y/7+ 4z/7
Step-by-step explanation:
isolate the variable, to do that divide each side by the factors that don't contain the variable
