Answer:
45 - 36 = 9
Step-by-step explanation:
Write 45 down first, move a ten from 40 to 5, subtract 15 - 6 then 30 - 30
The probability that all three are blue it's 3:14
Before we get started, it is good to remember PEMDAS - the acronym that tells you the order to carry out equations.
P = parentheses
E = exponents
M = multiplication
D = division
A = addition
S = subtraction
Knowing this, we should start by doing the equations <em>within </em>each parentheses.
So we did the addition and subtraction pieces within each group leaving us with the above equation. Now let's multiply:
20 is the answer.
To solve this problem, all you have to do is set the exponents equal to each other because the bases are the same.
2n=10
<em>*Divide both sides by 2*</em>
n=5
The answer is 5.
Hope this helps!
