Let speed of car be x mph
At 1pm, cargo is 26 mph * 1 hour = 26 miles away from intersection.
At 1pm, car is x mph*30 minutes = x/2 miles from intersection.
Since it is given they travel in opposite directions, and are 51 miles apart, we have
26+x/2=51
Solve for x
x/2=51-26=25 mph
x=25*2=50 mph.
Car was travelling at 50 mph
Answer:
The systems of equation for the amount spent are as follows
Step-by-step explanation:
In this problem we are expect to give a model or an equation that represents the amount of money spent per month given a fix subscription amount and a variable fee which is based on extra minutes spent.
let Y represent the amount of money spent in total for the month
The first case:
Subscription =$5
charges per minutes = $0.99
therefore the amount spent can be modeled as
The second case:
Subscription =$10
charges per minutes = $0.79
therefore the amount spent can be modeled as
Answer:
1. Write It Out:
Jay 4: Hena 3 : Sally 6
Jay is 24 years old.
2. Solve
So first you find 24/4 to get 6. This means Jays age was divided by 6 to get his ratio number. Showing that Hena's and Sally's is divided by 6 as well to get there ratios. Now what you need to do is mulitipy Hena and Sallys ratio by six to find there age's.
Hena: 3x6= 18 years old
Sally: 6x6= 36 years old
(Jay: 4x6= 24 years old)
Now to find there total age add them up...
18+36+24= 78
A. Sally is 36
B. 78
All you have to do is take 45$ and divide it by 1/3 then when you get that answer divide it by 1/4 to get your answer. So I believe your answer will be less than a dollar.
