Answer:
392153 to the nearest hundred is 392,200
Step-by-step explanation:
5x 3 1/2 = 3 x 5 1/2 is false
If the number only has 2 digits, it could only be 91, because since the tens digit is 8 more than the ones digit, the tens digit is greater than or equal to 8. it cannot be 10 or more, because that would make the number over 100, leaving only 8 and 9. If the tens digit is 8, the ones digit is zero, and since it cannot be zero, then the tens digit must be 9, leaving the ones digit to be 1. So, the final answer is 91.
Answer:
x = 5
Step-by-step explanation:
The ≅ sign means that both triangles are congruent, also meaning they're exactly the same. So with this in mind, the equations naturally equal each other:
3x + 3 = 5x - 7
Subtract 5x from both sides
-2x + 3 = -7
Subtract -3 from both sides
-2x = -10
divide by -2 to both sides
x = 5
