Answer:
98 or 18
Step-by-step explanation:
Let's call the numbers 3x and 7x. We have two cases, either 42 is 3x or 42 is 7x. Looking at the first case, if 3x = 42, x = 14 which means the other number is 7 * 14 = 98. Looking at the second case, if 7x = 42, that means x = 6 so the other number is 3 * 6 = 18.
For 24 keep the orders of operation in mind. So first we'd work out what's in parentheses, so we'd start by doing 5-3, which is 2. We'd then add 2+2 to get 4. Then we multiply 16 and 4 to get 64. So the correct answer is 64.
For the second part of 24 we first multiply 3 and 4 to get 9. We would then subtract 17-9 to get 8. Finally, we'd add 8+2 to get 10. So the correct answer is 10.
As for 25, the answer is 6400 centimeters^3.
