2x + 3y is less than or equal to 6

solve b=6c for c

The length of a rectangle is fixed at 15cm. What widths will make the perimeter greater than 80 cm?

solve the compound inequality:
6>-5x + 5 or 10 is less than or equal to -5x+4

• algebra -

1. 2x + 3y <= 6. Solve for ?

3y<= -2x + 6,
y = -2x/3 + 2.

2. b = 6c.
c = b/6.

3. Given: L = 15 cm.
2L + 2W > 80,
30 + 2W > 80,
2W > 80 - 30,
2W > 50,
W > 25 cm

4. I'm assuming both binomials =
-5x + 5.

6 > - 5x + 5 >= 10,
Subtract 5:
6 - 5 > -x >= 10 - 5,
1 > - 5x >= 5,
Multiply all terms by -5 and reverse
inequality sign:
1/-5 < x <= 5/-5,
-1/5 < x <= -1.

• algebra -

1. Ans: y <= -2x/3 + 2.
