Answer:
You can decide where to put the first digit because you know 153 doesn't fit into 6 or 61. But you know it can fit into 613. You put it there.
84 ÷ 2 = 42
Check it to make sure.
2 × 42 = 84
42 and 2 can be multiplied to get 84.
The answer is 132° because there angle CDE is 87° so you know it's more of that. And, 264° is way too wide.
A seven is a prime number because you can't divide it. 33 is a composite number because three can go into 33.
So for Tom to get his free meal he needs to spend 50 dollars.
This means the following⬇️

This equation is the 50 dollars he has to spend minus the 30.25 he has already spent which results in⬇️

This results in Tom needing to still spend 19.75 more dollars to get his free meal!!
Hope this helped!!
