How many 4 digit numbers that are multiples of 9?

Well, honey, to find the number of 4-digit multiples of 9, you just need to divide the largest 4-digit multiple of 9 (9999) by 9 and subtract the smallest 4-digit multiple of 9 (1008) divided by 9. So, 9999 ÷ 9 - 1008 ÷ 9 = 1111 - 112 = 999. That's right, there are 999 4-digit numbers that are multiples of 9.

Four consecutive multiples of 5 add up to 4130 what is the largest number?

To find multiples of a number we multiply that number with natural numbers, 1, 2, 3, 4, ... . Since those natural numbers are also called the consecutive positive integers, let's denote with x the first of the four consecutive positive integers whose product with 5 add up to 4,130. So we are adding these multiples of 5: 5x + 5(x + 1) + 5(x + 2) + 5 (x + 3) = 4,130 5x + 5x + 5 + 5x + 10 + 5x + 15 = 4,130 20x + 30 = 4,130 20x = 4,100 x = 205 Since we are interested for the largest multiple, then we have: x + 3 = 205 + 3 = 208 5 x 208 = 1,040. Thus, the largest number is 1,040.
