You can see by the image how did I get the answer
Answer:
2
Step-by-step explanation:
w + 1/2 ➡ (2w + 1)/2
w/4 + 2➡ (w + 8)/4
(2w + 1)/2 = (w + 8)/4
8w + 4 = 2w + 16 ➡ 6w = 12
w = 2
Find logarithm of both sides
log (3^x) = log 8
xlog3 = log8
x = log8/log3
x = 1.893
The first one is the second one. t(n)=20n+480
Question 4: is the first one t(n)=8n+15
Answer: the 3
Step-by-step explanation:
It goes ones, tens, hundreds, thousands, etc. You round the 3 (down, less than 5) because that is in the hundreds place.
