C) (3, 2)
Solve for x and y, then plug in (x, y)
2y = 4, 2y/2 = 4/2, y = 2
-x = -3, -x/-1 = -3/-1, x = 3
That would be .14
<em>How?</em>
Well that's easy all you have to do is set up 2.4÷16.8 Move the decimal over to the right to make it 24÷16.8 then at last you get dividing it. Do it how you would normally divide. Then you should get a huge decimal after you divide it. You want to round to the nearest hundredth (if necessary) so you should get .14 as your answer! Hope that helped!
Answer:
x=8, y=25. As a point it's (8,25)
Step-by-step explanation:
here is the system:
y=x+17
y=3x+1
notice how both of the equations equal y. Therefore, we can substitute one expression as y in the other expression. (It'll equal y=y, which is a true statement)
so it'll be:
3x+1=x+17
subtract 1 from both sides
3x=x+16
subtract x from both sides
2x=16
divide by 2
x=8
now, substitute 8 as x into one of the equations and solve for y
let's take the first one for example
y=8+17
y=25
so the answer is x=8, y=25. As a point it's (8,25)
Hope this helps!
Assume that the radius of the circle is 1.
The diagonal of the square is 2. By the Pythagorean Theorem, the side of the square of a right triangle will be 2/sqrt(2).
Finally, the ratio of the square to the circle, in area, will be
(2/sqrt(2))^2 : pi*(1)^2 = 2 : pi
We can conclude that the white area is about 35%.
You do mass divided by density
