1. Why is the idea of balance so important in the problem-solving strategy for solving an
equation?
2. You learned earlier that some problems can be rearranged or translated into more than
one mathematical sentence. For example, the equation t + 12 = 15 can be translated into
at least three other mathematical sentences. What are they? Create a simple equation of
your own and then translate it into its other forms.
3. Write your own word problem that can be translated into a simple math equation (like the
one shown in question #2). To solve your equation, what operation(s) would you have to
perform?

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
