Answer:
11+(2+y)
Step-by-step explanation:
The associative property says that you can move numbers inside the parentheses around if all the numbers are the same operation in a simple sense
So that means in this case: 2+(11+y)
We can switch the 2 and the 11 around since they are both the same, addition.
11+(2+y)
Joan's remaining distance is reduced by (600 ft)/(3 hours) = 200 ft/hour. She starts with 1600 ft remaining, so her distance remaining (y) after x hours is
.. y = -200x +1600
In order for the distance remaining to be zero, you must have
.. 0 = -200x +1600
.. 200x = 1600
.. x = 1600/200 = 8
It will take Joan 8 hours to hike 1600 ft.
Answer:
Step-by-step explanation:
Multiply both sides of the equation by e
d*e - 7*e = 4d + 3
de - 7e goes into the first box on top.
==================
The second box is obtained in two steps.
Step One
Add 7e to both sides.
de - 7e + 7e = 4d + 3 + 7e
de = 4d + 3 + 7e
Step Two
Subtract 4d from both sides.
de - 4d = 4d - 4d + 3 + 7e
de - 4d = 3 + 7e
de - 4d goes into the middle box.
================================
Take out d as a common factor
d(e - 4) = 3 + 7e
d(e - 4) goes into the third box from the top.
=============================
Divide both sides by e - 4
3 + 7e
d = ---------
e - 4

Step-by-step explanation:
Answer:
option D
Step-by-step explanation:
x-2y≥-12
-2y≥-x-12
y≤0.5x+6
has to be a solid line since y is less than or equal to 0.5x+6
so, options 1 and 3 are not applicable
also, in y≤0.5x+6 , y is less than or equal to this line, thus it only exists on the line and to the right of it (below it)
so, option 2 is wrong also, leaving us with option 4 or D, which in this case is the answer
