2001 gallons used in 5 days, so the average for one day is 2001/5=400.2 gallons.
The value of angle x is 127 degrees.
<h3>How to find angles?</h3>
The angle x can be found as follows:
Angle on a straight line is 180 degrees.
Therefore, the sum of 53 degrees and x degrees is 180 degrees.
Therefore,
53 + x = 180°(sum of angles on a straight line)
subtract 53 from both sides of the equation
53 - 53 + x = 180 - 53
x = 127°
Therefore, the angle of x is 127 degrees.

X=7 since you need to make an equation and in one hour you make $7. Don’t include the 1 as in 1x cause that’s incorrect
Answer:
see explanation
Step-by-step explanation:
(a)
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 3, y = 18 , then
18 = 3k ( divide both sides by 3 )
6 = k
y = 6x ← equation of proportion
(b)
(i)
when x = 12 , then
y = 6 × 12 = 72
(ii)
when y = 42
42 = 6x ( divide both sides by 6 )
7 = x
