Evaluate when a = 9, b = 6.
a-b over 3
A. 6
B. 9
C. 1
D. 3
When a = 9 and b = 6, the expression (a - b) / 3 evaluates to (9 - 6)/3 = 3/3 = 1.
Therefore, the answer is C. 1.
You are saving for a skateboard. Your aunt gives you $45 to start and you save $3 each week. The expression 45+3w gives the amount of money you save after w weeks. How much will you have saved after 4 weeks?
A. $42
B. $57
C.$576
D $33
To find out how much money you will have saved after 4 weeks, we can substitute w = 4 into the expression 45 + 3w.
45 + 3(4) = 45 + 12 = 57
Therefore, you will have saved $57 after 4 weeks.
Therefore, the answer is B. $57.
To evaluate the expression (a - b) / 3 when a = 9 and b = 6, follow these steps:
Step 1: Substitute the given values of a and b into the expression:
(9 - 6) / 3
Step 2: Perform the subtraction:
3 / 3
Step 3: Perform the division:
1
Therefore, when a = 9 and b = 6, (a - b) / 3 equals 1.
The correct answer is C. 1.
To evaluate the expression (a - b) / 3 when a = 9 and b = 6, you need to substitute the values of a and b into the expression and then perform the mathematical operation.
So, (a - b) / 3 = (9 - 6) / 3.
Now, subtracting 6 from 9 gives us 3.
So, the expression becomes 3 / 3.
Dividing 3 by 3 gives us 1.
Therefore, when a = 9 and b = 6, (a - b) / 3 = 1.
Hence, the answer is option C. 1.
