Eight addition equations that have a sum of 10

1. 5 + 5 = 10
2. 8 + 2 = 10
3. 7 + 3 = 10
4. 6 + 4 = 10
5. -6 + -4 = 10
6. -7 + -3 = 10
7. -8 + -2 = 10
8. -5 + -5 = 10

0+10 ; 1+9 ; 2+8 ; 3+7 ; 4+6 ; 5+5 ; 1.5+8.5 ; 2.5+7.5

Answer: the correct answer is 10step-by-step explanation: let the number be n, then the expression becomes,then“twelve more than the quotient of a number and two, decreased by four” iswhen n=4,we substitute 4 whetever we see n to get,we simplify to obtain,we further simplify to get,therefore the correct answer is c.
