Answer:
$61
Step-by-step explanation:
Given
Number of days, x = 5
Expenditure per day, E'(x) = 10x + 11
Required
Determine the expenditure per day (E'(x))
From the question, we have that
![E'(x) = 10x + 11](https://tex.z-dn.net/?f=E%27%28x%29%20%3D%2010x%20%2B%2011)
Substitute 5 for x
![E'(5) = 10 * 5 + 11](https://tex.z-dn.net/?f=E%27%285%29%20%3D%2010%20%2A%205%20%2B%2011)
![E'(5) = 50 + 11](https://tex.z-dn.net/?f=E%27%285%29%20%3D%2050%20%2B%2011)
![E'(5) = 61](https://tex.z-dn.net/?f=E%27%285%29%20%3D%2061)
Hence, the expenditure for 5 days is $61
328 because 82/3 multiplied by 12 is 328 and you do that because there's 12 months in a year and if you spend 82/3 hours per month playing soccer than you would multiply that by 12 which gives you 328 hours.
Answer:
x+2y=0
Step-by-step explanation:
399.6 square meters
7•8/2=28
28•3=84
8•6.9/2=27.6
(12•8)•3=288
84+27.6+288=399.6
Answer:
y = 3x - 23
Step-by-step explanation:
y + 4 = 3(x - 9)
y + 4 = 3x - 27
y = 3x - 23
