Answer:
80 893 720
Step-by-step explanation:
hope dis helps!!!!
4x^2 = 12x
4x^2 - 12x = 0
4x(x - 3) = 0
4x = 0
x = 0...not this one
x - 3 = 0
x = 3 <== ur number
If 2 gallons of oil are used a day, than he will need 60 gallons of oil, because 30x2=60. For 60 gallons of oil, you would have to have 12 drums because 60÷5=12. Because there is already 8 drums of oil, there would already be 40 gallons because 8x5=40. If the owner already had 40 gallons of oil, they would only have to get 20 more gallons because 60-40=20. That would be 4 drums because 20÷5=4. The owner would have to order 4 more drums of oil.
Answer:63 cm
Step-by-step explanation:
Given
The scale of creation is 2:9
The width of the toy wheel is 14 cm
Suppose x is the actual width of the truck
![\therefore \dfrac{2}{9}=\dfrac{14}{x}\\\\\Rightarrow x=\dfrac{9}{2}\times 14=63\ cm](https://tex.z-dn.net/?f=%5Ctherefore%20%5Cdfrac%7B2%7D%7B9%7D%3D%5Cdfrac%7B14%7D%7Bx%7D%5C%5C%5C%5C%5CRightarrow%20x%3D%5Cdfrac%7B9%7D%7B2%7D%5Ctimes%2014%3D63%5C%20cm)
Thus, the width of actual truck is 63 cm
