Answer:
23
Step-by-step explanation:
1 + 4 = 5 so we get 1 4 5
then 4+5 = 9, 1 4 5 9
5+9 = 14, 1 4 5 9 14
9+14 = 23, so
1 4 5 9 14 23
23 is the 6th number in this sequence
1.5. please mark me brainliest answer if i helped !! thanks
A. the end of the equation is a set amount because there is no exponent with it, so the answer would be 11.32
B) replace x with 10 and solve the equation:
y = 1.84(10) +11.32 = 18.40 + 11.32 = $29.72
C) The number with the exponent would be the increase per hour, the answer would be $1.84
Answer:
30 miles
Step-by-step explanation:
We know
D = RT
Where
D is the distance
R is the rate
T is the time
<u>Towards Island:</u>
R = 15
Let time be x
So, we can write:
D = 15x
<u>Return from Island:</u>
R = 10
Let time be y
So, we can write:
D = 10y
Also, total time is 5 hours, so we can write:
x + y = 5 [equation 2]
Now, since the distance for both legs of the journey is equal, we can write:
Distance 1 = Distance 2
15x = 10y
Now we replace this equation with equation 2, so we get:
Equation 2: x + y = 5 or x = 5 - y
15x = 10y
15(5 - y) = 10y
75 - 15y = 10y
75 = 25y
y = 75/25
y = 3
Distance 2 = D = 10y
Replacing y with 3, we get:
D = 10y
D = 10(3)
D = 30
So, the distance to island is 30 miles
