Given:
hours parking charge
4 5.50
7 7.75
7 - 4 = 3 hours
7.75 - 5.50 = 2.25
2.25 / 3 = 0.75
0.75 is the change in amount for every hour spent. It is the variable unit rate
4 hours is 5.50.
Cost of parking for 3 hours is: 5.50 - 0.75 = 4.75
0.75 x 4 hours = 3
5.50 - 3 = 2.5 fixed charge.
total parking charge: y = 2.50 + 0.75x
Answer:
D or the last one.
Step-by-step explanation:
Honestly, you got me kinda confused. Is it saying that there is multiple equations to answer this? Well anyways, D would be the answer. When the variable (w) is beside the coefficient, it means you multiple them together. (W) standing for weeks multiplied by 12 which is how much you earn each week would get you the total amount. The rest just don't make sense.
Answer:
x = 14
Step-by-step explanation:
Two lines given in the picture intersect each other at a point.
Given angles are the linear pair of angles.
Since, linear pair of the angles is supplementary,
(7x - 1)° + (6x - 1)° = 180°
(7x + 6x) + (- 1 - 1) = 180
13x -2 = 180
13x = 180 + 2
x = 
x = 14
Therefore, x = 14 will be the answer.
