A way to remember what you have learned is creating notes or doing practice problems
The equation is:
2/3n + 4 = 7
(.1mi/1min)
1.39mi/13.9 min
You have to multiply the bottom and the top by the same number to get the answer, you're trying to make the denominator 13.9 for the amount do minutes so you multiply the numerator by 13.9 to get the numerator
25.
The area is b * h, so
(2x + 7) * 4
which is greater than 100 units, so
(2x + 7) * 4 ≥ (don't look at =; only major) 100
8x + 28 ≥ 100
8x ≥ 100 - 28
8x ≥ 72
x ≥ 9
26.
The perimeter is 2 * (b + h), so
2 * (2x + 7 +4) = 2 * (2x + 11)= 4x + 22
which is greater than 50 units, so
4x + 22 ≥ (don't look at =; only major) 50
4x ≥ 50 - 22
4x ≥ 28
x ≥ 7
A graph is similar to a data table in that they both present the data. A difference is that the graph is more of a visual representation. Often, trends in the data are easy to recognize in the visual representation of the graph.
