I) 4 Gallons

II) $77

Step-by-step explanation:

30km 1 gallon

420km ?

420 ÷ 30 = 14

? = 40

So, 4 gallons more will be needed to complete the journey.

1 gallon $5.50

14 gallon $?

14 x $5.50 = $77

The cost of the petrol is $77

Complete the solution of the equation. fine the value of y when x equals 4.
Helen [10]

y = - 5

substitute the value of x = 4 into the equation and solve for y

- 12 + 9y = - 57 ( add 12 to both sides )

9y = - 45 ( divide both sides by 9 )

y = \frac{-45}{9} = - 5

Marina86 [1]
To find perimeter, you use this equation for a parallelogram:
2l+2w=p
Let’s not put the numbers in,
2(12)+2(8)
24+16
40
So b, 40 yards is how much he walked.
