since the number is going on the opposite it must be a negative integrer.
and since the number was 6 units away from 0, it should be the half point between the points.
number = 3
since it is going in the oppsoite direction it should be -3
Lucas rode 1,000 meters b/c
2 klm is = to 2000 meters.
and 1/4 of 2000 meters is 500 meters but then he had
to turn back to go home so that's another 500 meters and in total he rode 1,000 meters.
7+18/(6-3)
7+18/3
25/3=8.333
The system:
3 x + 4 y = 40
x + 6 y = 18,
-------------------
x = 18 - 6 y
3 ( 18 - 6 y ) + 4 y = 40
54 - 18 y + 4 y = 40
54 - 40 = 18 y - 4 y
14 = 14 y
y = $1
x = 18 - 6
x = $12
Answer: Each DVD costs: $12.
Answer:
You have
21
dimes and
7
quarters.
Explanation:
Let
x
be the number of quarters, and
3
x
the number of dimes.
The amount of money you have can be written as
0.25
x
+
0.1
⋅
3
x
=
3.85
.
Now isolate
x
to find the number of quarters:
0.25
x
+
0.1
⋅
3
x
=
3.85
0.25
x
+
0.3
x
=
3.85
0.55
x
=
3.85
x
=
3.85
0.55
=
7
=
the number of quarters.
Then multiply by three to get the number of dimes:
7
⋅
3
=
21
