I'll do problem 24 to get you started

-3a + 5 < -7

-3a + 5-5 < -7-5 ..... subtract 5 from both sides

-3a < -12

-3a/(-3) > -12/(-3) ... see note below

a > 4 is the answer

To graph this, we plot an open circle at 4 on the number line. Shade to the right of the open circle. The open circle tells the reader "do not include this value as part of the solution set".

note: in that step I divide both sides by -3 to fully isolate 'a'. Dividing both sides by a negative number will flip the inequality sign.

The area of the circle shown would not be 5pi. If you look closer, the area is 25pi, therefore the answer is 3. I hope this helps!

a shipment of sugar fills 4 1/3 containers. if each container holds 2 1/7 tons of sugar, what is the amount of sugar in the enti
emmasim [6.3K]

To find the answer we need multiply the number of containers by number tons of sugar each container has.

(4 1/3 )*(2 1/7).

To calculate , we need to convert mixed numbers into improper fractions.

4 1/3 = (4*3 +1)/3 = 13/3

2 1/7 = (2*7+1)/7 =15/7

(4 1/3 )*(2 1/7) = (13/3) * (15/7) = (13*5)/7 = 65/7 = 9 2/7 (tons)

Answer: 9 2/7 tons.
