Question

Can some one help me with this math problem.

Select ALL of the equivalent equations.
a. 1.2 = 1.8 + m
b. 1.2 – m = 1.8
c. 1.8 – 1.2 = m
d. m + 1.2 = 1.8
e. 1.2 – 1.8 = m
f. m = 1.2 + 1.8

please respond before 11/6/15

Answer 2

i don't want an answer just help i don't quite get it

Answer 3

I don't know that this is a complete definition for equivalent equations but it will suffice for this problem, I think.

Two equations are said to be equivalent if they have exactly the same solutions.

Sample Problems
•The equations x = 1 and 2x = 2 are equivalent, since the only solution to either equation is 1.
•The equations 2x = 0 and 3x = 0 are equivalent, since the only solution to either equation is 0.
•The equations x = 1 and x = 2 are not equivalent, since their solutions, 1 and 2, respectively, differ.

Answer 4

I suggest that you solve each of the given equations for m and look for those equations which have the same solution.

To help you get started:

a. 1.2 = 1.8 + m

Subtract 1.8 from both sides

1.2 - 1.8 = m
- .6 = m

b. 1.2 – m = 1.8
Subtract 1.2 from both sides

-m = 1.8 - 1.2
-m = .6
Multiply both sides by 1

m = -.6

Therefore, equations A and B are equivalent.

That leaves four more for you to solve.
