Step-by-step explanation:

4k <_ 4 = numerical form

4k/4 <_ 4/4

k <_ 1 = work to solve

on number line there is 0,1,2. 1 has a circle that is filled in and arrow pointing towards 0. = graphed on number line

set notation = {k(vertical bar)k<_1}

interval notation = (-infinity, 1]

36 girls

step-by-step explanation:

the 48 boys is 4 parts of the ratio

divide 48 by 4 to obtain one part of the ratio

= 12 ← 1 part of the ratio

3 parts = 3 × 12 = 36 ← number of girls

40 x 50 = 2000
