Step-by-step explanation:
s1 = 3
s2 = 3×2 = 6
s3 = 6×2 = 12
s4 = 12×2 = 24
s5 = 24×2 = 48
sn = sn-1 × 2 = s1 × 2^(n-1)
s17 = 3 × 2¹⁶ = 3 × 65,536 = 196,608
Answer:
220 - a = m
Step-by-step explanation:
a is her age
Can we have the answer choices please?
-1 is what you’d reduce it to
<span>12(X+20)=372
12X+240=372
Subtract the 240
</span>12X=372-240 ----> 12X=132
Divide by 12
12X/12=132/12 ---> x = 11
