Answer:
Step-by-step explanation:
f(x) = -5x + 8(7 - x)......when f(x) = 160
160 = -5x + 8(7 - x)
160 = -5x + 56 - 8x
160 - 56 = -5x - 8x
104 = - 13x
-104/13 = x
-8 = x <====
1. A, It goes past the 4, but the circle is not shaded because the answer cannot be 4
2. C. It goes below the 11 and is shaded because it can be equal to 11

35.5 - 31.25 = 4.25 ounces of cream could be added
Answer:
50
Step-by-step explanation:
34%=34/100
34/100 = 17/50
1.98 x 10^-12 1.98
------------------ = ---------- x 10^-10
3.6 x 10^-2 3.6
=0.55 x 10^-10
=5.5 x 10^-11
