Heellpp me pls which equation can be used to solve the problem .60 percent of what number is 30 . 60x2 = 120
this is a
30x2 = 60

30 divide 1 = 30 this is b

60 divide 1 = 60

60 divide 2 = 30
this is c
100 divide 2 = 50

100x2=200
this is d
30x2 =60

NOTE pls vote and do not guess i will brainest you if right

The ratio of two numbers is 5 to 4. the sum of the numbers is 99. what number is the greater of the two numbers?

Which statement about the relative areas of δabc and δxyz is true? the area of δabc > the area of δxyz the area of δabc < the area of δxyz the area of δabc = the area of δxyz more information is needed to compare.

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?
