5a+3b = 24
(5+a)(3+b) = 49
The order of steps are different because one requires multiplication then addition while the other one requires addition then multiplication. But one sure thing is that they both need substitution.
4)
pine tree is most numerous on tree farm which is 40%
5)
if 480 trees total,
pine trees = 480 x 0.40 = 192 trees
6)
if 480 trees total,
spruce trees = 480 x 0.30 = 144 trees
(p.s. also firm trees = 144 (same as spruce trees)
Log8 2 = x
by the definition of logs, we can write
8^x = 2
8^(1/3) = 2
so x = 1/3
or we could solve it by using log to base 10 and use our calculator
log 8^x = log 2
x log 8 = log 2
x = log 2 / log 8 = 0.333.... = 1/3
Step-by-step explanation:
Simple events in probability have a certain chance of happening. For example, a 10% chance of rain today. When two or more probabilities are possible, they are added together to get the total probability. A 10% chance of snow and a 15% chance of hail would mean a 10% + 15% = 25% chance of bad weather. This article will show you how to find the probability of a simple event happening.
