3 ft = 1 yd, Sandy has 156 ft of fabric = 52 yds
52 ÷ 7/8 = 52 × 8/7
52 × 8 = 416 ÷ 7 = 59 scarves.
Answer:
168
Step-by-step explanation:
The first equation given as 
Where a is the number of adults and b is the number of students
<em>Since, the number of students are given as 82, we can plug 82 into b and then do algebra and solve for a (shown below):</em>
<em>
</em>
<em />
<em>Thus, </em><em>168 adult tickets were sold</em>

I think that is the biggest 5 digits odd number...
Answer:
b. x = 11/8, x = 59/72.
Step-by-step explanation:
4|8x - 6| = 5|-8x + 7|
square both sides:
16(64x^2 - 96x + 36) = 25( 64x^2 - 112x + 49)
1600x^2 - 1024x^2 - 2800x + 1536x + 1225 - 576 = 0
576x^2 - 1264x + 649 = 0
x = [1264 +/- √(1264^2 - 4 * 576* 649)] / (2*576)
x = 11/8, x = 59/72.
