Vesnalui [34]

Complete question is;

Jackson has to repaint some classroom bookcases. He has 2 gallons of paint. All the bookcases are the same size and each requires 2/5 gallon of paint. How many bookcases is he able to repaint with the amount of paint?

Answer:

5 books

Step-by-step explanation:

Jackson has 2 gallons of paint

Now, for us to find the number of bookcases the Jackson will be able to repaint if each bookcase requires 2/5 gallon, we will just divide 2 by 2/5

Thus;

Number of book cases Jackson will be able to repaint = 2 ÷ 2/5

Thus gives; 2 × 5/2 = 5 books

taurus [48]

We are given that the insect can lift 1.182 x 10^3 times it's own weight. Say that w is weight, so the lift is:

lift = 1.182 x 10^3 * w

 

Assuming that your body weight is 60 kg, therefore you can lift:

lift = 1.182 x 10^3 * 60 kg = 70,920 kg

Solve for X: 1/3 (2x - 8)=4.
Veseljchak [2.6K]

Answer:

x = 10

Step-by-step explanation:

1/3 (2x - 8)=4.

Multiply each side by 3

1/3 *3(2x - 8)=4.*3

2x-8 = 12

Add 8 to each side

2x-8+8 =12+8

2x = 20

Divide each side by 2

2x/2= 20/2

x = 10
