Sara received $100 for her birthday and her friend, Sam, received $125 for his birthday. Sara earns $10 every Saturday for walking her neighbor's dog. Sam earns $8 every week for watering the garden. Sara and Sam are saving their birthday money and their weekly earnings to attend summer camp. Which inequality can be used to find x, the number of weeks it will take for Sam to have saved more than Sara?

F

125 100 8x - 10x

G

125+ 8x 100 + 10x

H

125 + 10x > 100 + 8x

J

125 8x 100 - 10x

Find x & pleeeeaaaassseeee me !

The following division is being performed using multiplication by the reciprocal find the missing numbers is 5/12 divided by x/3 equals 5/12 times x/10 equals 1/x

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis. 3- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in part b?
