Answer:
k>-2
Step-by-step explanation:
4k+15>-2k+3
4k-(-2k)+15>3
4k+2k+15>3
6k+15>3
6k>3-15
6k>-12
k>-12/6
k>-2
Heather runs 7 miles in 80 minutes.
At the same rate, how many miles would she run in 64 minutes?
Let x represent miles would she run in 64 minutes?
Question Sets Up the Proportion
7/80= x/63 |Cross Multiplying to solve for x
x = 7*64/80
x = 5.6mi
Hope this helps!
The answer is 8
8*2=16-4=12
Look carefully at the point where the 2 lines intersect. From that point, look straight down to the x-axis; you'll see that the x-value there is 50. Similarly,
starting at the intersection, look straight left to the y-axis; the y-value there is 11.
Thus, the coordinates of the intersection (i. e., the solution) are found in (50,11).
3/6 = 6/12 15/30
5/6 = 25/30 10/12
6/10 = 12/20 24/40
1/2 = 4/8 5/10
