I found the missing data:
table:
foot length (in) Shoe size(S)
8 6
8.5 7
9 8
9.5 9
10 10
Choices:
<span>S = x – 2
S = 2x – 10
S = x + 6
S = 2x + 4
</span>
Among the choices, the correct equation is S = 2x - 10
S = 2(8) - 10 = 16 - 10 = 6
S = 2(8.5) - 10 = 17 - 10 = 7
S = 2(9) - 10 = 18 - 10 = 8
S = 2(9.5) - 10 = 19 - 10 = 9
S = 2(10) - 10 = 20 - 10 = 10
No she cannot, the fabric is not long enough.
Let's look at the math; half a disk takes 40 seconds to rip, and two halves make a whole, so 40 + 40 = 80 and that's your answer
