Answer:

-1<x<1

Step-by-step explanation:

Subtract 1 on both sides:

-6x>-6

Divide -6 on both sides:

(since you are dividing by a negative you switch the sign)

x<1

subtract 4 on both sides:

3x>-3

Divide 3 on both sides:

x>-1

Thus -1<x<1

Hope this helps!

Three pounds of lawn seed covers 1800 square feet how many 4 pound bags are needed to cover 8400 square feet.
VikaD [51]
You need to find the unit rate of 3 : 1800 first by dividing 1800 and 3

1800 ÷ 3 = 600

So this means for every 1 pound bag it covers 600 square feet. You now need to multiply 600 and 4 to see how many square feet 4 pounds cover.

600 × 4 = 2400

So each 4 pounds covers 2400 sq ft. Now you have to divide 8400 and 2400 to find how many bags of 4 pounds you need

8400 ÷ 2400= 3.5

You need 3.5 bags of 4 pounds.
Technically you would need 4 bags because you’d have to round it up.

Hope this helps you!! :)

A bag contains:
Lady bird [3.3K]

Answer:

3/50

Step-by-step explanation:

There are 5 + 4 + 2 + 6 + 3 = 20 marbles in the bag

P(draw a black) = 6/20 = 3/10

If the black marble is replaced, then there are 20 marbles in the bag again.

P(draw a blue) = 4/20 = 1/5

P(draw a black and blue with replacement) = (3/10)(1/5) = 3/50
