Write one digit on each side of 10 to make a four digit multiple of 72. how many different solutions does this problem have?

Step-by-step explanation:

72 is the product of 8 and 9, so the number needs to be divisible by both 8 and 9.

The number 100 is divisible by 8 with a remainder of 4, so to make it have no remainder, we must add another 4 to the number: 104. We cannot have any other digit in the ones place (x) and have 10x be divisible by 8.

The 4-digit number must have a sum of digits that is divisible by 9 if it is to be divisible by 9. 104 has a sum of digits of 5, so we must have another digit of 4 to get a number divisible by 9. There is no other single digit that will do.

The number we're looking for is 4104 = 72·57. There are no other solutions.

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
