4/6=20/30 and 1/5=6/30. 20-6= 14. 14/30 simplified is 7/15. C IS YOUR ANSWER.
Answer:
1. Convert the x-coordinate from Mixed number to Decimal number.
2. Move over 2.5 units to the left.
3. From -2.5, move down 4 units.
4. Mark the point.
Step-by-step explanation:
By definition, a coordinate plane is formed by the intersection of two perpendicular lines: The y-axis (which is a vertical line) and the x-axis (which is an horizontal line). The point in which the y-axis and the x-axis intersect is known as "Origin" and has the following coordinates:
You have this point:
You can identify that the x-coordinate is:
Since it is a Mixed number you can convert it into a decimal number dividing the numerator 1 by the denominator 2 and adding the result to the Whole number part 2. Then:
And the y-coordinate is:
To plot the point:
- Start at the Origin.
- Move over 2.5 units to the left (because the x-coordinate is negative).
- Then, from -2.5 you must move down 4 units (because the y-coordinate is negative).
- Mark the point.

Answer:
The surface area of a rectangular box is the sum of the areas of the flat rectangular faces of the box. The height is the vertical side of the box. So the other sides are the length and width. Try to picture a box in your head, or you can draw it on paper.
Let x = length
Let y = width
Let h = height
Using these variables, we can write an equation that represents the surface formula.
A = 2(area of bottom face) + 2(area of front face) + 2(area of side face)
A = 2xy + 2xh + 2yh
This is general equation for surface area. All we need to do is plug in the known values into it and solve for h.
496 = 2(18)(8) + 2(18)h + 2(8)h
496 = 288 + 36h + 16h
Now it comes down to simple algebra. Isolate the h terms and solve for h from there.
208 = 52h
Divide both sides of the equation by 52 to get your height. I let you finish up here.
