ANSWER
The approximate solution is
EXPLANATION
The point of intersection of the two lines is the solution of the linear systems represented by the graph.
From the graph we can determine that each box is 2 units.
From the graph, when we start at O and count two boxes to the right and half box down, we obtain the point of intersection of the two lines to be
Note that since each box is two units, half way between the boxes gives one unit.

Answer:
Check below
Step-by-step explanation:
1) Check the rectangle below with a line k, the axis of rotation in the center of the figure.
2) Since it has a perimeter of 32 units and it is to be rotated about the line, the solid to be created it is a cylinder. As you can see below.
3) Let's calculate its radius, based on the information given, i.e. the perimeter:
Since the line of rotation is the center, and the radius is half the line segment of the basis, then the radius is 5.
Answer:
3
Step-by-step explanation:
The fractions are: and
. Let's take a look at the denominators: 5 and 3. The LCD of 5 and 3 is 15. 5x3=15, 3x5=15. So now we would multiply the denominators to make them the same number like this:
and
. Remember that if you multiply the denominator by a certain number, you must multiply the numerator by the same number as well. For example, in
, we multiply 3 by 5 and 2 by 5. Same number. Now with that out of the way, let's work on the equation:
+
. We know it is the same as
and
. So now all we do is add the numerators together: 5+10=15 or
. Now we have to reduce the fraction.
can be reduced to 3 by dividing 15 by 5=3. The final fraction is
or can be simply put as 3 since 3/3 is a whole number. That's it - you're done!
