I’m not entirely sure but the answer might be 72 1/2 miles. I added up 12 1/3, 8 3/4, 17 2/8, 23 2/3, and 10 5/10. And I got 72 1/2.
Brianna's thinking is wrong because obviously all of the expressions are going to equal -4 when x is 0 because -4 would be the only value. Also, if x was a different number, the expressions wouldn't be equivalent. The equivalent expressions are A. 9x - 3x - 4, and C. 5x + x - 4. This is because when both are simplified, they equal 6x - 4.
I believe the answer is 3/8. The whole portion of employees, which is translated as 8/8 is deducted by 5/8, which is the population of male employees.
1. RM = SN, TM = TN Addition Property of Equality
2. ∠T = ∠T Reflexive
3. RM + TM = SN + TN Substitution
4. RM + TM = RT, SN + TN = ST Betweeness
5. RT = ST CPCTE
6. Triangle RTN congruent to Triangle STM Given
7. RN = SM SAS
