Integer put 7 for tenth put 6.8 if that’s not right then do .8
Are you talking about the angles in a triangle? Your question is not clear. I'll assume you are talking about a triangle.
Angle 1 + Angle 2 + Angle 3 = 180°
4x + 15 + 2x + 16 + x = 180°
Solve for x to find Angle 3, which in this case is the value of x.
Answer:
In total,
permutations of three items can be selected from a group of six distinct elements.
In particular, there are
ways to order three distinct items.
.
Step-by-step explanation:
The formula
gives the number of ways to select and order
items from a group of
distinct elements.
To select and order three items from a group six distinct elements, let
and
. Apply the formula:
.
In other words, there are
unique ways to select and order three items (select a permutation of three items) from a group of six distinct elements.
Consider: what's the number of ways to order three distinct items? That's the same as asking: how many ways are there to select and order three items from a group of three distinct elements? Let
and
. Apply the formula for permutation:
.
To find the permutations, start by selecting one element as the first of the list. A tree diagram might be helpful. Refer to the attachment for an example.
X in less than or equal to 4.5. it is this because 32 is the least number of miles per gallon. 144/32=4.5.
