D is days
m is miles
0.16m + 64d (this is rate 1)
0.08m + 128d ( this is rate 2)
since you plan to rent for one day, input d as 1.
0.16m + 64(1)
0.08m + 128(1)
i hope i gave you enough hints
Answer:
a=19
Step-by-step explanation:
Since it is a parallelogram, adjacent angles are supplementary, or add to 180 degrees.
In this parallelogram, 5a+1 and 3a+27 are adjacent. Therefore, when added, they should equal 180.
5a+1+3a+27=180
Combine like terms
(5a+3a) + (1+27) = 180
8a +28 =180
Now, solve for a, by isolating it.
Subtract 28 from both sides
8a+28-28=180-28
8a=152
Divide both sides by 8
8a/8=152/8
a=19

Answer:
1. Angle Addition Postulate/Theorem
2. 90°
3. m<AOC; Vertical Angles
4. 90°; 110°
5. 20°
Step-by-step explanation:
1. m<DOB = m<DOE + m<BOE (Reason: Angle Addition Postulate/Theorem)
2. m<DOB = 90° + x (Reason: Substitution)
Note: m<DOE is a right angle.
3. m<DOB = m<AOC (Reasons: Vertical Angles)
4. 90° + x = 110° (Reasons: Substitution)
5. x = 20° (Reasons: Algebra)
Note how we got 20° by applying algebra:
90° + x = 110°
Subtract 90° from both sides
90° + x - 90° = 110° - 90°
x = 20°
