Write one digit on each side of 15 to make a four digit multiple of 15. how many different solutions does this problem have? the possible solutions

There are 6 solutions

Step-by-step explanation:

All multiples of 15 are multiples of 5, then all finish in 0 or 5. Therefore, the four digits possibilities are:  1150 , 1155 , 2150 , 2155 , 3150 , 3155 , 4150 , 4155 , 5150 , 5155 , 6150 , 6155 , 7150 , 7155 , 8150 , 8155 , 9150  and 9155 . Only 1155 ,  3150 , 4155 , 6150 , 7155  and 9150  are multiples of 15.

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
