Two cargo trains are linked together, making of a total of 22 cars. The cars from one of the trains are carrying 15 tons each, a

DochEvi [55]

Let x be the number of 20 ton cars

Then,
380<{15(22-x)+20x}<400
380<{330-15x+20x}<400
380<{330+5x}<400

Subtract 330 on both sides
50<5x<70

Divide both sides by 5;
10<x<14

Therefore, the range of 20 tonne cars is between 10 and 14 cars.

Check whether (0, -2) is solution of the equation x - 2y = 4 or not

kaheart [24]

Answer:

Step-by-step explanation:

Plugin x = 0 & y = -2 in the LHS of the equation. After substituting, if you get the RHS, then this point is the solution of the equation.

x - 2y = 0 - 2*(-2)

= 0 + 4

= 4 = RHS.

(0,-2) is solution of the equation.
