Answer:
Step-by-step explanation:
Step one:
given
cost per drive= $20
additional fee per person= $4
let the number of persons be p
and the total cost be C
The total cost function is expressed as
Step two:
Required:
<u><em>We want to make P subject of the cost function </em></u>
Take 20 to the other side we have
C-20=4p
divide through by 4
P=C-20/4
simplify
P=C/4-5
Answer: x = 27
Step-by-step explanation:
2x+3x+45=180º because all of the angles of a triangle add up to 180
5x=180-45
5x=135
x=135/5
x=27
8*10*14 = 1120
10*8*10 = 800
1120+800 = 1920
volume =1920 cm3
