(5+6=miles per hour)
i hope this helps
so look...
m=miles
(5m+6=m)<------ answer
hope this helps
(a)
different possibilities
(b)
So, there is a 1 in 4 chance that both dice will show an even.
Answer:
The origin.
Step-by-step explanation:
0 belongs in none of these quadrants but in the origin. The origin is the center dot in the middle of all quadrants.

Answer:
$2.50
Step-by-step explanation:
The question asks for the total cost of a notebook and pen together. We don't need to find their individual costs in order to answer the question.
Sometimes we get bored solving systems of equations in the usual ways. For this question, let's try this.
The first equation has one more notebook than pens. The second equation has 4 more notebooks than pens. If we subtract 4 times the first equation from the second, we should have equal numbers of notebooks and pens.
(8n +4p) -4(3n +2p) = (16.00) -4(6.50)
-4n -4p = -10.00 . . . . . . . . . . . simplify
n + p = -10.00/-4 = 2.50 . . . . divide by the coefficient of (n+p)
The total cost for one notebook and one pen is $2.50.

<em>Additional comment</em>
The first equation has 1 more notebook than 2 (n+p) combinations, telling us that a notebook costs $6.50 -2(2.50) = $1.50. Then the pen is $2.50 -1.50 = $1.00.
One could solve for the costs of a notebook (n) and a pen (p) individually, then add them together to answer the question. We judge that to be more work.
ASA we need a second angle that is next to the side
SAS we need a side next to the angle
Choice B
