1520 yards
Step-by-step explanation:
Explanation:
Remember that
1
mile is
1760
yards, so
2
miles is
1760
⋅
2
, or
3520
yards.
If she has walked the track
5
times, then the total distance she has walked is
400
⋅
5
, or
2000
yards.
Do
3520 yards (
2 miles) minus
2000
yards, the distance Keisha has already walked.
3520 − 2000 = 1520
Answer:
Step-by-step explanation:
The second set. It contains (2,2) and (2,7), so it fails the vertical-line test.
Answer:
0.44
Step-by-step explanation:
-3x^2 + 2y^2 + 5xy - 2y +5x^2 - 3y^2
Combine like terms
-3x^2 + 5x^2 = 2x^2 2y^2 - 3y^2 = -1y^2
2x^2 - 1y^2 + 5xy - 2y
Now plug in the solutions Note: it is easier if you have all decimals or all fractions (-1/10=-.1
2(0.5)^2 - 1(-0.1)^2 + 5(0.5)(-0.1) - 2(-0.1)
Simplify:
0.5 - 0.01 - 0.25 + 0.2
0.5 + 0.2 - 0.01 - 0.25
0.7 - 0.26
0.44
