Initialfee+variablefee=total
initialfee=12
variaablefeet=hours times 5
total=27
27=12+5 times hours
minus 12 both sides
15=5 times hours
divide both sides by 5
3=hours
rented 3 hours
Answer:
D: 14 = 0.89 x n; 15.7
Step-by-step explanation:
To get 89% of a number you have to multiply that number by 0.89
<u>Statement </u> <u>Reason</u>
1. AB = x + 16 1. Given
BC = 4x + 11
AC = 77
2. AB + BC = AC 2. Segment Addition Postulate
3. x + 16 + 4x + 11 = 77 3. Substitution Property
4. 5x + 27 = 77 4. Simplification <em>(added like terms)</em>
5. 5x = 50 5. Subtraction Property of Equality
6. x = 10 6. Division Property of Equality
7. AB = 10 + 16 7. Substitution Property
8. AB = 26 8. Simplification <em>(added like terms)</em>
(t + 8) (-2) = 12
Distributive property >>> -2t + -16 = 12
Inverse operation >>>> -2t + -16+16 = 12+16
Simplify >>>> -2t = 28
Divide >>>> -2t/-2 = 28/-2
Final answer >>>> t = -14
