I assume you want to find x
remember, you can do anything to an equation as long as you do it to both sides
7x-4=-2x+1+9x-5
group like terms
7x-4=-2x+9x+1-5
add like terms
7x-4=7x-4
add 4 to both sides
7x=7x
divide both sides by 7
x=x
true
x=all real numbers
since it sipmlifies to x=x (it could somiplify to 0=0 as well), it is an identity and all real numbers work for x
I hope this helps you
base= b
height=b-1
Area=base×height/2
15=b. (b-1)/2
b. (b-1)=30
b=6
b-1=5
A 25% it is right I believe
Answer:
The probability that the sum of the numbers rolled is either a multiple of 3 or an even number is 24/36 = 2/3
The two events are mutually exclusive
Step-by-step explanation:
we first need to create a table of the sample space from the experiment, the sum of the numbers rolled. Find the attached for a depiction of the possible outcomes.
The probability that the sum of the numbers rolled is either a multiple of 3 or an even number will be given by counting the numbers that are either even or multiples of 3 and then dividing by the number of possible outcomes, 36.
In our case this will be;
24/36 = 2/3
