Answer:
25x + 15800
Step-by-step explanation:
Given
The amount of money in both banks over time represented by the functions;
f ( x ) = 50 x + 6500 and g( x ) = − 25 x + 9300
The total amount of money in the two accounts over time is expressed as;
h(x)= f(x) + g(x)
Substitute;
h(x) = 50 x + 6500 + (− 25 x + 9300)
h(x) = 50x - 25x +6500+9300
h(x) =25x + 15800
Hence the sum of the money in the account over time is 25x + 15800
Answer: 0.7272 minutes = 43.632 sec
Step-by-step explanation:
Cary could run 5½ miles in 4 minutes,
How minutes would it take her to complete 1 mile?
5½miles = 11/2 miles = 5.5 miles.
5.5 miles = 4 minutes
1 miles = x minute
x = (1 * 4) / 5.5
X = 0.7272 minutes = 43.632 seconds
Cary used 43.632 seconds to complete 1 mile
