B-2.5mph You divide 10 (how far you went) by 4 (the amount of time it took you) which gives you 2.5 (the amount of time it takes you to walk 1 mile) To check: It takes you 2.5 hours to walk 1 mile so multipling 2.5 by 4 tells you how far you walked in 4 hours
1) We know that volume= base area x height, so 306.52= 19.4 x height.
To find the height you have to divide 306.52/19.4 which would give you the height. The height is 15.8m.
The total fair is $27
To find the cab per mile element - subtract the $3 - giving $24
The divide this number by the number of miles
Ans 3
Ok let's translate question mathematically.
Let x be first number
y be second number
z be third number
So this question says
y = 2x
z = 2+5x
y+z = 37
So we need so solve those equations.
Use first and second into third:
(2x) + (2+5x) = 37
7x + 2 = 37
7x = 35
x = 5
Now plug x value into first and second equation:
y = 2(5)
y = 10
z = 2+5(5)
z = 2+25
z = 27
So the answer is
First number is 5, second number is 10, and third number is 27
Answer:
-2.5 is the value of x in this question
