1/2(8x -2) + ( -2x + 1/4)
(4x -1) + (-2x + 1/4)
=
(2x - 3/4) or (2x - 0.75)
C. 5/2.
You can get the scale factor by putting the measurements of similar sides on a fraction,
In this case 20/8 =5/2, 10/4 = 5/2
Step-by-step explanation:
T = beads of Ting Ting = 165
S = beads of Sherie.
R = beads of Roxanne.
S = 4/5 × T = 4/5 × 165 = 4 × 33 = 132 beads
R = 1/2 × S = 1/2 × 132 = 66 beads
Ting Ting has therefore 165 - 66 = 99 more beads than Roxanne.
