Determine which equation is true:
1.) 7 + 6 = 0 +5 is 13
Explanation:
7 + 6 = 0 + 5
= 13 - 5
= 8 is not equal to 13
2.) 9 + 3 = 0 +7 is 19
Explanation:
9 + 3 = 0 + 7
=10 - 7
= 3
= 3 is not equal to 19
3.) 13 + 0 = 20 is 7
Explanation:
13 + 0 = 20
= 20 - 13
= 7
7 = 7
Correct
4.) 12 x 10 = 120 + 5 = 125 - 25 = 100
Explanation:
12 x 10 = 120
120 + 5 = 125
125 - 25 = 100
Correct
Final answer:
13 + 0 = 20 is 7
and
12 x 10 = 120 + 5 = 125 - 25 = 100
are correct equations.
