Answer:
<em>x = 9</em>
Step-by-step explanation:
-2x + 3 = -15
-2x = -15 - 3
-2x = -18
x = 9
Hope this helps! :)
You follow the same steps to get the product
Answer:
exactly 10: 8.33 %
at least 10: 16.66 %
Step-by-step explanation:
first we have to see the amount of favorable results
4+6 = 10
6+4 =10
5+5=10
then we have to see the amount of possible results
Each dice has 6 faces and there are 2 dice, so if we make 6 ^ 2 we will get the number of possible combinations
6^2 =
6*6 = 36
Now we only do the number of favorable results on the possible results and multiply it by 100 and obtain the probability
100*3/36 = 8.33 %
we do the same for those greater than or equal to 10
4+6 = 10
6+4 = 10
5+5 = 10
6+5 = 11
5+6 = 11
6+6 = 12
100*6/36 = 16.66 %
We can rewrite this problem as:
What is 60% of 35?
"Percent" or "%" means "out of 100" or "per 100", Therefore 60% can be written as
60
100
.
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the number of members we are looking for "m".
Putting this altogether we can write this equation and solve for
m
while keeping the equation balanced:
m
=
60
100
×
35
m
=
2100
100
m
=
21
21
members must be present to have a vote.
Your basically just adding 9 so 4 plus 9 is 13 and 13 plus 9 is 22
