The answer is 9. 7 times 9 is 63 and then 63 divided by 3 is 9.
Replace the x with 9, and the y with 1.
(x · y²)/-5 becomes (9 · 1²)/-5
1² is just 1, so you're doing 9 × 1 (which is = 9) over -5.
Therefore, your final answer is -9/5.
The pentagon does not belong because it has 5 sides while the other 3 shapes have only 4 sides.
Answer:
C.
Step-by-step explanation:
H(arold) = 2 + 2*K(enneth)
H = 2 + 2K
H + K = 38
Substitution:
2 + 2K + K = 38
3K = 36
K = 12
Kenneth solved 12 problems and Harold solved (2(12) + 2 = 24 + 2 =) 26 problems
