Answer:
13 Quarters
Step-by-step explanation:
Let <u>D</u> and <u>Q</u> stand for the numbers of Dimes and Quarters.
We are told that:
D + Q = 31
We also find that:
D = Q + 5
Use the second expression (for D) in place of D in the first equation:
D + Q = 31
(Q+5) + Q = 31
2Q = 26
<u>Q = 13</u>
This means there are:
D = 13 + 5 or <u>18 Dimes</u>
======================
Check
D + Q = 31 ?
18 + 13 = 31 <u> YES</u>
D = Q + 5 ?
18 = 13 + 5 <u>YES</u>

Step-by-step explanation:

Parallel lines have the same slope. for example, the two lines y = 6x + 3 and
y = 6x - 5 are parallel because they have the same slope, 6x.
the slopes of perpendicular lines are opposite reciprocals, which means that you would flip the numbers of the fraction and make it negative. for example, the opposite reciprocal of -3x is 1/3x.
also, parallel lines never intersect, whereas perpendicular lines intersect at a 90 degree angle.
therefore, it isnt possible for two lines to be both parallel and perpendicular.
Answer:
see the explanation
Step-by-step explanation:
Let
x ----> number of adult tickets
y ----> number of children tickets
we know that
Jane sold 100 tickets for her school auction
so
----> equation A
Jane collected a total of $944
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (36,64)
see the attached figure
therefore
The number of adult tickets sold was 36 and the number of children tickets sold was 64
