24
this is how it breaks down
-15 + x = 9
=> x= 9 + 15
=> x= 24

If a number is added to itself, it is twice that number → 18 ÷ 2 = 9 → 9 + 9 = 18
No, because for a number to be divisisble by 9, it's digits (2,6 & 7) must add together to produce a number divisible by 9. 2+6+7=8+7=15. Is 15 divisible by 9? No, so we can conclude that 267 is not divisible by 9.
N + 9
No 9 and 15 is not a number, they are two numbers.
y + 6 + 6 = 15 15-6-6 = y 9-6 = y 3 = y
The number is 9, because 9 + 2/3(9) is 15, so 9 + 6 = 15 because 2/3 of 9 is 6.
To solve for the value of the blank, we need to divide 135 by 9. This gives us 15, so the blank must be filled with the number 15. This is because 9 multiplied by 15 equals 135.
Doubling the numerator gives 2 × 9 = 18 To have a result of 1, the numerator and denominator must be the same. Thus the denominator needs to be 18. 18 - 16 = 2 → 2 must be added to the denominator.
.9
18+x=27 calculate and your answer should be 9.
Nope - in order for a number to be divisible by 9, the sum of its digits must also be divisible by 9. In this case, the digits 2+4+2+7=15.
