1. 0.91<0.93; 0.91 is farther away from the whole number 1 so it is less than 0.93.
2. 0.5=0.50; 0.5 and 0.50 are the same, since the decimal can be written with or without the zero.
3. 1.08<1.6; 1.08 is farther away from the whole number 2, so it is less than 1.6.
A − 3b = 16
a = b − 2
b - 2 - 3b = 16
2b = - 18
b = - 9
a = - 9 - 2
a = - 11
(-11,-9)
-12x^5y^7
Just sum the power and multiply the constants
1. 2
2. 1
3. 6
I'll post the rest in the comments
