How to solve the inequality
beks73 [17]

Answer:

x\geq 19/6

Step-by-step explanation:

1. Multiply both sides by 6 (the LCM of 6,3)

5/2 + 3-x <= 2(x-2)

2. Simplify 5/2+3-x to 11/2-x

11/2 - x<=2 (x-2)

3. Expand.

11/2-x<= 2x-4

4. Add x to both sides.

11/2<= 2x-4+x

5. Simplify 2x-4+x to 3x-4.

11/2<=3x-4

6. Add 4 to both sides.

11/2+4<=3x

7. Simplify 11/2+4 to 19/2

19/2<=3x

8. Divide both sides by 3

19/2 /3 <=x

9. Simplify 19/2 /3 to 19/2*3

19/2*3<=x

10. Simplify 2*3 to 6

19/6<=x

11. Switch sides.

x>= 19/6

Hope this helps!

Answer:

Radius: 22 Circumference: 138.23

Step-by-step explanation:

The radius is half of the diameter so 44/2 is 22.

The circumference can be found by 2*pi*r or pi*d.

2\pi22 or \pi 44

I have 50 to spend at beach. A kayak cost 5 per hour to rent. I buy lunch for 8.50. I want to save 15 for food later. How many h
Gekata [30.6K]

Answer: you can rent the kayak for 5.3 hours

Step-by-step explanation:

Total amount of money that you have to spend at the beach is 50.

A kayak cost 5 per hour to rent. This means that if you rent the Kayak for X hours, the amount that you will spend would be 5×x = 5x. I buy lunch for 8.50. I want to save 15 for food later. This means that total amount of money spent is the sum of money spent in renting the kayak and buying of lunch.

Total amount spent = 5x + 8.50

Total amount spent + Total amount that you want to save = Total amount of money that you have to spend at the beach. Therefore

5x + 8.50 + 15 = 50 - 15 - 8.5 = 26.5

x = 26.5/5 = 5.3
