Answer:
x=-1, y=-3. (-1, -3).
Step-by-step explanation:
x+y=-4
3x-6y=15
---------------
x=-4-y
3(-4-y)-6y=15
-12-3y-6y=15
-12-9y=15
9y=-12-15
9y=-27
y=-27/9
y=-3
x+(-3)=-4
x-3=-4
x=-4+3
x=-1
Answer:
The height between the two trees will be 1.67 feet.
Step-by-step explanation:
What you do is you take the 1/2 have and times it by 6 because it is every two years that the tree grows 1/2 of a foot. So it will be 3 feet. The other tree grew 4 inches in 3 years so it will be 16 inches you will then have to make the 16 inches into feet to get 1 1/3. You will then minus the 3 feet and the 1 1/3 to get 5/3 or 1.67 feet.
Answer:
850.
Step-by-step explanation:
Let the number at the start be x shoes. Then:
x - 50 - 0.64(x - 50) = 288
x - 0.64x - 50 + 32 = 288
0.36x = 288 + 50 - 32
0.36x = 306
x = 306/0.36 = 850.
