What does the variable a equal when a = 4.9?
3a + 6a = ?
a = 4.9
That is not the answer Ms. Sue. The answer is 44.1
The question asks "What does the variable a equal when a = 4.9?"
44.1 is the answer when you substitute 4.9 for a in the problem.
To find the value of the variable "a" when "a = 4.9," we simply substitute the value of "a" into the expression. So, when "a = 4.9," we have:
3a + 6a = 3(4.9) + 6(4.9)
Next, we calculate the value of each term:
3(4.9) = 14.7
6(4.9) = 29.4
Now, we substitute these values back into the expression:
3a + 6a = 14.7 + 29.4
Finally, we perform the addition and obtain the final result:
3a + 6a = 44.1
Therefore, when "a = 4.9," the expression 3a + 6a equals 44.1.
