Answer:
From the information given
x is time for which she ran at speed of 6mi/h and
y is time for which she biked at speed of 12.5 mi/h
total time = 3.5 h
total distance = 34 mi
so
6x + 12.5y = 34 and
x + y = 3.5
x = 3.5 - y
6 ( 3.5 - y) + y = 34
6.5y = 13 which gives
y = 2 and this
x = 1.5
so suze ran for 1.5 h and biked for 2 h
CHECK
speed of run X time of run + speed of biking x time of biking must be = total distance covered
6 × 1.5 + 12.5 × 2 = 9 + 25= 34 mi
which is true
199 + 100 = 299 (original price)
100 / 299 = 0.334 = 33.4% off
Given
Grant and Pedro are comparing their stocks for the week
On Monday, their results were opposite.
for Monday if Grant lost $4
Explain how you would graph their results for Monday.
To proof
let us assume that value of stocks after a week = x
As given in question
for Monday if Grant lost $4
i.e x= - $4
result were opposite for grant and pedro.
thus
for Monday if Pedro gain $4
i.e x = $4
Therefore two values are
x = -4 and x = 4 is shown in graph given below.
This shows that x = -4 lies left of 0 to x-axis and x = 4 lies right of 0 to x- axis.
The answer is the first choice, 3(w-4)=5.
3 times = 3
a number minus four = (w-4)
is five = 5
I hope this helps.
Answer:
Poor Alex, I know how they feel, I got a dog myself.
The amount of time between
11:41 pm to 12:09 am is
19 minutes (to 12 am, 60 minutes to next hour) + 9
which is 28 minutes for the first dog barking session
the second time is 35 minutes,
using same method as before.
adding the two separte barking sessions we get
35+28= 63 minutes
which is equivelant to 1 hour and 3 minutes.
In conclusion the dog barks for 1 hour and 3 minutes in total.
