The answer you are looking for could either be 16 or 40. To solve the equation, you would follow the steps of PEMDAS. Since the 2 above the equation is an exponent, you'd first solve there.
Fill in "a" and "b", the equation will now say 2^2 * 3 + 4 = ?. Assuming that the exponent is meant to go with the 2 alone, 2 * 2 = 4. This leaves the equation to say 4 * 3 + 4 = ? Multiply 3 and 4 to get 12, then add 4 to get 16.
OR
Fill in "a" and "b". This time, we're assuming that the exponent is going with 2 * 3 (originally 2a). Multiply 2 and 3 to get 6, then square 6 to get 36. Finally, add 4 to 36 to get 40.
I'm not quite sure where the exponent was meant to go, but I hope this helps!
If there are 14 tens, that is 14 multiplied by 10. 14 x 10 = 140.
140 is the answer.
Hope this helps :)
I think the answer would be 8 but I'm not sure
Answer:
Becky saves $4.86 by choosing to buy 18 bulbs in the 3 package sets
Step-by-step explanation:
Becky has 2 options here. She can buy 3 for $4.20 or 2 for $3.34. We can easily determine the prices because both 2 & 3 are factors of 18.
18 / 3 = 6, so multiply 6 * 4.20 to see that 18 bulbs will cost $25.20
18 / 2 = 9, so multiply 9 * 3.34 to see that 18 bulbs will cost $30.06
Now, we can see that buying sets of 3 is cheaper, we need to determine how much we are saving by choosing the cheaper option. (Use subtraction)
$30.06 - $25.20 = $4.86
