Answer:
K = 51/3.
Step-by-step explanation:
K = 51/3.
K = 17.
#22)
4(t - 8) + 20 = 5
Distribute the 4.
4t - 32 + 20 = 5
Combine like terms.
4t - 12 = 5
Add 12 to both sides.
4t = 17
Divide both sides by 4.
t = 4.25
#24)
17 = -5(3 + w) + 7
Distribute the -5.
17 = -15 - 5w + 7
Combine like terms.
17 = -8 - 5w
Add 8 to both sides.
25 = -5w
Divide both sides by -5.
w = -5
#26)
9 = -(r - 5) + 11
Distribute the -.
9 = -r + 5 + 11
Combine like terms.
9 = -r + 16
Subtract 16 from both sides.
-7 = -r
r = 7
