x=quantity of days
$38.00+$2.75x=$31.75+$4.00x
We can cancel all $...
38.00+2.75x=31.75+4.00x
It is just as important to cancel symbols as numbers.
Next, we isolate x.
We will begin by subtracting 31.75 from both sides...
-31.75+38.00+2.75x=4.00x
6.25+2.75x=4.00x
Then, we will divide both sides by 4.00...
(6.25/4.00)+((2.75x)/4.00)=(4.00x)/4.00
1.56+0.69x=x
Then, we will subtract 0.69x from both sides...
-0.69x+1.56+0.69x=x-0.69x
1.56=0.31x
Then, we will divide both sides by 0.31...
1.56/0.31=(0.31x)/0.31
5=x
Let's check our numbers...
The original equation was...
$38.00+$2.75x=$31.75+$4.00x
38.00+2.75(5)=31.75+4.00(5)
38.00+13.75=31.75+20.00
51.75=51.75
Answer:
285 I believe
Step-by-step explanation:
109 + (109 + 67) = total
109 + 176 = total
total = 285
Answer:
a) The maximum height is approx 15.5 unit.
b) The time it will take for Joey to reach the water is 1.45 hour.
Step-by-step explanation:
Given : When Joey dives off a diving board, the equation of his pathway can be modeled by 
To find : a) Find Joey's maximum height.
b) Find the time it will take for Joey to reach the water.
Solution :
Modeled ....(1)
a) To find maximum height
Derivate (1) w.r.t. t,
For critical point put h'=0,
Derivate again w.r.t. t,
It is maximum at t=0.46875.
Substitute t in equation (1),
The maximum height is approx 15.5 unit.
b) To find the time it will take for Joey to reach the water.
Put h=0 in equation (1),
Apply quadratic formula, 
Here, a=-16 , b=15, c=12
Reject negative value.
The time is t=1.45.
The time it will take for Joey to reach the water is 1.45 hour.
