Let the three numbers be x, y and z respectively, then
x + y + z = 62 . . . (1)
y = x - 4 . . . (2)
z = 4x . . . (3)
The above three expressions could be used to represent the numbers.
Solving the three equations, putting (2) and (3) into (1) gives
x + x - 4 + 4x = 62
6x - 4 = 62
6x = 62 + 4 = 66
x = 66/6 = 11
x = 11.
y = 11 - 4 = 7
z = 4(11) = 44
x = 11, y = 7, z = 44.

Answer:
300 miles
Step-by-step explanation:
Let
x ----> the number of miles
y ----> the total cost for rent a car
we know that
The equation of the line in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
<u><em>Prestige car rentals</em></u>
we have that
The slope is equal to 
The y-intercept is 
therefore
-----> equation A
<u><em>Gateway auto</em></u>
we have that
The slope is equal to 
The y-intercept is 
therefore
-----> equation B
For what number of miles both companies charge the same price>
Equate equation A and equation B

solve for x

Mel's Age = xRahfat's Age = x-3Aurelio's Age = 2x 2x + x +x -3 = 574x -3 = 574x = 60x = 15So Mel's age is 15.Hope this helps! :D
Answer:
5r + (5 x 6) = 84
looking for rice per pound.
Step-by-step explanation:
5r + (5 x 6) = 84
This shows an equation where we need to make r the subject to establish how many pounds a bag of rice weighs.
5r + (5 x 6) = 84
5r + (30) = 84
5r = 84-30
5r = 54/5
r = 10 4/5
r = 10.8 pounds
