Answer:
x= 3, y= -2
Step-by-step explanation:
5x+3y= 9
x= 25÷7 + 2÷7 y
5(25÷7 +2÷7 y)
5( 25÷7 +2÷7 y ) + 3y= 9
y= -2
x= 25÷7 + 2÷7 x (-2)
x= 3
Length of the model on the bottom = (5 x 18) / 3 = 30 cm
You just take the 32 and multiply it by 8, so the answer would be 256 km. Since the bus can go 32 km in half an hour, in four hours it would go 8 times that distance.
The height is 5 and 1/4 then the base is 2 and 1/2
You can convert these fractions into decimals and them multiply them to get your area.
