Answer:
13 centimeters per day.
Step-by-step explanation:
We have been given that during summer, the water level of the river increased by 78 centimeters in 6 days. We are asked to find the water level increase rate in centimeters per day.
To find the water level increase rate per day, we will divide total increase by total days as:


Therefore, the water level increase rate is 13 centimeters per day.
The algebraic equation is 4(0.25)+2x=17
STEP 1: Simplify both sides of the equation
1+2x=17 or 2x+1
STEP 2: Subtract both sides
2x = 16
STEP 3: Divide both sides by 2
2x/2 = 16/2
x = 8

Write a recursive rule for the sequence.
-2,0,2,4,6
STEP 1:
a1 = -2
a2 = 0
a3 = 2
STEP 2:
d = a2-(a1)=a3
= d = 0-(-2)=2
STEP 3:
An = a+(n-1)d
