Final answer:
Both given equations, 5.26 + 8.37 = 13.63 and 8.37 + 2.05 = 10.42, are made true when 8.37 is used. The number 8.37 completes these equations correctly.
Step-by-step explanation:
The student is asking which equations would be made true when the number 8.37 is substituted into them. Each equation requires an addition or subtraction operation to check whether 8.37 completes the equation correctly. Let's look at the given equations and insert 8.37 appropriately.
- 5.26 + 8.37 = 13.63
- 8.37 + 2.05 = 10.42
To find out which of these equations are correct, we'll add or substitute 8.37 and see if the equation balances correctly. We also need to make sure to express each answer with the proper number of significant figures, rounding as necessary.
For 5.26 + 8.37, we get 13.63, which is exactly the sum on the right side of the equation, so this equation is true.
For 8.37 + 2.05, we get 10.42, which is exactly the sum on the right side of the equation, so this equation is also true.
Therefore, both equations provided would be made true when 8.37 is used.
