4+2x=9
-4 -4
2x=9
2x/2 9/2
x=4 1/2
9+4x=2x-1 2x=-10 x=-5
y + 6 + 6 = 15 15-6-6 = y 9-6 = y 3 = y
The greatest single-digit number that occurs twice on either side of 8 is 9. This can be represented as 9, 8, 9.
No. It is a sum of four terms which can be simplified to a sum of three terms.
3 plus x = 9
Half of 18 is 9 and 5+4 = 9 so the number is 5
Nine less than twice a number equals the same number increased by four?
The relevant inequality is 2n - 9 >= 24
7 (Seven) is the next number in your sequence ! Plus four minus two plus four minus two plus four minus two and so on and so on !
In standard arithmetic, four plus four equals 8. However, in certain mathematical systems, such as modular arithmetic, where numbers "wrap around" after reaching a certain value, four plus four can equal 9. This is because in modular arithmetic, numbers are considered congruent if they have the same remainder when divided by a specific number, known as the modulus.
half a number
um, 9.
It is 9.
To write "twice a number plus six is greater than nine" as an inequality, let the number be represented by the variable ( x ). The expression can be written as ( 2x + 6 > 9 ). This inequality states that when you multiply the number ( x ) by two and then add six, the result is greater than nine.
9+4x=2x-1 2x=-10 x=-5
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
If a number is added to itself, it is twice that number → 18 ÷ 2 = 9 → 9 + 9 = 18
