Answer: 27.33.
Explanation:
To solve the equation "What number times 3 plus 8 equals 90", we can use algebraic expressions.
Let's assume the unknown number is "x".
The equation can be written as:
3x + 8 = 90
Subtracting 8 from both sides of the equation, we get:
3x = 82
Dividing both sides by 3, we get:
x = 27.33
Therefore, the number that times 3 plus 8 equals 90 is approximately 27.33.
