You need to make a series of equations from what you are given first. I am going to use the first letter of each of the names to represent the length of that persons wire.
1/2s=2/5d
3c=s
s+d+c=6 ft
Okay. Now you can combine the first two equations knowing what s equals:
1/2(3c)=2/5d
d=15c/4
Now you have d=15c/4 and s=3c, so you can replace d and s in the third equation.
3c+15c/4+c=6
Then solve for c and plug it into the equation 3c=s to find the length of sarah's wire.
The answer is:
8 / (2/3) =
8 * 3/2 =
24/2 =

Answer:
B. x ≥ -3
Step-by-step explanation:
-4 x - 10 ≤ 2
add ten by both sides
-4x≤12
divide -4 by both sides
x ≤ -3
BUT because you divded you have to switch the sign so
x ≥ -3
8/40=?/120 40x3=120 8x3=24 so 24 pages or 24/120
If one book = 1/8, then you can just multiply it by 3, for the three mystery books. 8x3= 24, so tony has 24 books in all.
