2x + 7 = 30 - 7 - 7 2x = 23 x = 23/2 x = 11.5
is equal to -23 -2*x
If you mean... -7+x*2=23 then x = 15. Done without the aid of a calculator ! The value of 'x' (the unknown number) MUST equal 30, because 30-7=23 - SO, half the unknown number must be 15!
To find one tenth of a number, multiply the number by 0.1. For example, one tenth of 23 is equal to 23 x 0.1 = 2.3
Find the square root of 23. The second one is the same number with a negative sign.
3(x+21) = 2(x+23)3x+63=2x+46x=-17
2x + 7 = 30 - 7 - 7 2x = 23 x = 23/2 x = 11.5
is equal to -23 -2*x
61 + 23 = 84
Well, darling, let's break this down. Let's call the first number x and the second number y. According to the problem, we have the equation x = 2y + 5 and x + y = 23. By substituting the first equation into the second equation, we get 2y + 5 + y = 23, which simplifies to 3y + 5 = 23. Solving for y, we find y = 6. Plugging y back into x = 2y + 5, we find x = 17. So, the numbers are 17 and 6.
The two numbers are 9 and 23. 23-9 = 14 23-(2*9) = 5
Every next number is increased by 5. The next number in the sequence is 23.
If you mean... -7+x*2=23 then x = 15. Done without the aid of a calculator ! The value of 'x' (the unknown number) MUST equal 30, because 30-7=23 - SO, half the unknown number must be 15!
You need at least two numbers to find a GCF.
34 is halfway between 23 and 45 inclusively.Therefore, 34 x 2 = 68
Only 23 has prime factorization of 23.
They are itself and one because 23 is a prime number
