The river will not reach a level of 7 ft. after 5 hours.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the height of the water level after x hours.
Since the river is 1 ft below its average water level and begins to rise by a constant rate of 1.5 ft per hour. Hence:
b = -1, m = 1.5. The equation becomes:
y = 1.5x - 1
To reach a level of 7 ft. That is y = 7:
7 = 1.5x - 1
1.5x = 8
x = 5.3 hours
The river will not reach a level of 7 ft. after 5 hours.

Step-by-step explanation:
sorry about my old answer i clicked the wrong number
1/2 hour = 30 mins
30 x 2 = 60 mins = 1 hour

Humans are made out of many things; such as: carbon, hyrdogen, nitrogen, oxygen, calcium, and phosphorus. Those are just the composition of the body. We are also made out of 70% of water, a child will have 300 bones and an adult will have 206 bones, four basic types of tissue, and muscle.
Hope this helped!
