25% of 60 to 40% of 30<br> &gt;, &lt; or =
Travka [436]

You can reduce the percentages to fractions:

25\% = \dfrac{25}{100} = \dfrac{1}{4}

40\% = \dfrac{40}{100} = \dfrac{2}{5}

So, we have

25\% \text{ of } 60 = \dfrac{1}{4}\cdot 60 = 15

40\% \text{ of } 30 = \dfrac{2}{5}\cdot 30 = 12

The graph shows two lines, A and B. A graph is shown with x- and y-axes labeled from 0 to 6 at increments of 1. A straight line
maxonik [38]

there will be one solution because the lines intersect at exactly one set of points.

(0,6)(6,3)
slope(m) = (3-6) / (6-0) = -3/6 = -1/2

y = mx + b
6 = -1/2(0) + b
6 = b
y = -1/2x + 6

(0,0)(6,6)
slope(m) = (6-0) / (6-0) = 6/6 = 1

y = mx + b
6 = 1(6) + b
6 = 6 + b
6 - 6 = b
0 = b

y = x + 0

x = -1/2x + 6
1/2x + x = 6
1/2x + 2/2x = 6
3/2x = 6
x = 6/(3/2)
x = 6 * 2/3
x = 12/3 = 4
