Tanya writes the number 7.05. bryce says he can write a different number using the same digits. is he correct?

Yes, actually a couple:
different number with same digits (ex):

7.05
7.50
5.07
5.70
0.57
0.75
705
70.5
75
750
570

etc

hope this helps

1. use commutative property to reorder the terms.2x+81=0.2. move the constant to right side by adding its opposite on both sides. 2x+81-81=0-81.2x=(-81).3. divide the equation on both sides.2x ÷ 2 = 81 ÷ 2.x = -81/2. your answer is -81/2. if you need to simplify it into a decimal, it’s -40.5.
