The sum of two postitive integers, a and b, is least 30. the difference of the two integers is at least 10. if b is the greater integer, which system of inequalities could represent the values of a and b.

The right system is a + b ≥ 30 , b ≥ a + 10

Step-by-step explanation:

∵ The sum of them is at least 30 means the smallest value is 30

∴ Their sum is a + b = 30 or greater than 30

∴ a + b ≥ 30

∵ Their difference is at least 10 and the greater is b

∴ b - a = 10 or greater than 10

∴ b - a ≥ 10

∴ b ≥ a + 10

So the right system is the first answer

a + b ≥ 30 , b ≥ a + 10

step-by-step explanation:

what is the figure? attach a picture.

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
