Given:
Speed of Timmy = 5 miles per hour
Speed of sam = 4 miles per hour and head start of 2 miles
To find:
Where Timmy and Sam will meet.
Solution:
Let x be the number hours they ran in marathon and y be the total distance covered.
Speed of Timmy is 5 miles per hour. So, total distance covered by Timmy in x hours is
[tex]y=5x[/tex] ...(i)
Speed of sam is 4 miles per hour and head start of 2 miles. So, total distance covered by sam in x hours is
[tex]y=4x+2[/tex] ...(ii)
Now, equate (i) and (ii).
[tex]5x=4x+2[/tex]
[tex]5x-4x=2[/tex]
[tex]x=2[/tex]
The value of x is 2. It means they will meet after 2 hours.
Put x=2 in (i).
[tex]y=5(2)[/tex]
[tex]y=10[/tex]
It means, they will meet at 10 miles.
A local specialty store sells two brands of yogurt. Brand A is a fruit yogurt that comes in a 12-ounce container for $2.88. Brand B is a fruit yogurt that comes in a 16-ounce container for $4.48. Which one is a better buy: Brand A or Brand B?
Answer:
0.04
Step-by-step explanation:
Brand A:
so x is equal to 0.24
Brand B:
so x is equal to 0.28
Now the difference of cost would be Brand B - Brand A which would give you 0.04.

3. If f(x) = 12x + 14, what is the range value for the domain value 3?
Answer:50
Step-by-step explanation:
You are given the domain value which is your "x".
So to solve the problem you fill x as 3
Making the equation f(x)=12(3)+14
12 * 3 = 36
36+14=50
There is your answer!

A car can travel 480 miles on a full tank of petrol. The tank holds 60 litres. The fuel gauge shows there and 15 litres left in the tank. How many more miles can the car travel before it runs out of petrol?
Answer:
Miles= 120
Step-by-step explanation:
Giving the following information:
A car can travel 480 miles on a full tank of petrol. The tank holds 60 liters.
First, we need to calculate the miles per liter:

Miles per litre= 8 miles
Now, the miles that can be driven with 15 liters:
Miles= 15*8
Miles= 120

In Exercises 1 and 2, identify the slope of the line. Then identify a point the line
passes through.
1. y - 2 - 4(x - 5)
2. y - 7 - -3(x + 6)
Answer:
1. Slope = 1/4
Point = ( 1, 1 )

Step-by-step explanation:
1)There are whole numbers that are not integers.
true or false
2)All rational numbers are whole numbers.
true or false
3)All integers are whole numbers.
true or false
4)All integers are rational numbers.
true or false
Answer:
1).false 2). false 3).true 4). true
Step-by-step explanation:
1).All whole numbers are integers, so s...” That's right! All whole numbers are integers, so since 0 is a whole number, 0 is also an integer.
3).. Integers include all whole numbers and their negative counter part e.g. … -4, -3, -2, -1, 0,1, 2, 3, 4,… Where a and b are both integers. is a rational number but not an integer. 4). All integers are rational number. Since we can rewrite an integer into a fractional form by diving it by 1. For example, 4=41 4 = 4 1 . But not all rational numbers are integer.

Step-by-step explanation:
The ratios are 2:1
In the table it shows 4:2, 8:x, y:6, 20:z
To find if the ratios are equivalent we would need to plug in
Once plugging in answer B we get 4:2, 8:4, 12:6, 20:10 which would all equate to 2:1
Answer:
Its B

I need help with this question
Can someone plz help me with this????
Answer:
since we cant see what info is given maybe these tips can help...
the 'b' is also called the y-intercept, the y-int is what you start of with. Example, if your parents give you $20 and you spend $5 every week, your y-int is 20
The m is the slope, so if your parents give you $20 and you spend $5 every week, your slope is -5 because your money is decreasing at a linear rate
the x is the input, so if you want to know how much money you have 2 weeks after you got $20, you would substitute x with 2, and solve to get $10
