Answer: w = 9
Isolate the variable by dividing each side by factors that don't contain the variable. First, we rearrange the terms.
18 + 4w = 6w
4w + 18 = 6w
Now we subtract 18 from both sides.
When we simplify, we get that w = 9.

Hope this helps =)
There should be no problem in finding the value of the unknown variable "b" in the equation given in the question.The equation is solvable for finding the value of "b" because it is the only unknown variable in the single equation that is given in the question.
45 = 3b + 69
Let us reverse both sides of the equation first. then, we get
3b + 69 = 45
3b = 45 - 69
3b = - 24
b = - (24/3)
= - 8
So from the above deduction, we can easily conclude that the value of b in the given equation is -8.

Answer:
D. Cannot be determined without seeing the data.
Step-by-step explanation:
Option “D” is correct because age is a quantitative variable but if we look at the exact number or exact age of the car then the car’s age is quantitative discrete but if we look at the age of the car by going a number of years then it will be continuous. Therefore, without getting the exact information of the age of the car we cannot predict the type of variable. So the option “D” best fit for the answer.
