7 x 20 = 140
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

Answer:
Step-by-step explanation:
A rectangle has same opposite sides and 4 right angles as property of a rectangle.
The photo frame has different diagonal lengths
It makes opposite sides different, therefore it is not a rectangle
<u>Given angles (x - 20) and (x + 40) are consecutive interior angles which add up to 180°</u>
- x - 20° + x + 40° = 180°
- 2x + 20° = 180°
- 2x = 160°
- x = 80°
