Since a = b - 2, we can substitute this value into the other equation to find the value of b.  Once we have a value for b, we substitute it back into one of the equations to find the value for a.

a - 3b = 16
b - 2 - 3b = 16
-2 - 2b = 16
-2b = 18
b = -9

Now substitute back into the equation

a = b - 2
a = -9 - 2
a = -11

Solution set in the form (a, b) is...

(-11, -9)

Explain How you can use base ten blocks to find 1.54 + 2.37
Elena-2011 [213]
1.54 + 2.37 

= (1 + 5/10 + 4/100) + (2 + 3/10 + 7/100)

= 1 + 5/10 + 4/100 + 2 + 3/10 + 7/100

= 3 + 8/10 + 11/100

= 3 + 8/10 + (10/100 + 1/100)

= 3 + 8/10 + (1/10 + 1/100)
= 3 + 8/10 + 1/10 + 1/100

= 3 + 9/10 + 1/100

= 3.91
