Step-by-step explanation:

x+2y=-4

2x+3y=1

The difference between this two equations is x+y so:

x+y

=1-(-4)

=1+4

I'm not sure what the question is asking to find, but I have already helped you find the value of x+y, good luck with the rest I guess :))

Aidan took a 1020 km trip, travelling by Bus and By Train. The bus travelled at 105 km/h, and the train travelled at 160 km/h. T

bazaltina [42]

Answer:

523.6 km

Step-by-step explanation:

Let x represent the distance traveled by train. Then 1020-x is the distance traveled by bus. The travel times are given by the relation ...

time = distance/speed

Then the total travel time in hours is ...

x/160 +(1020-x)/105 = 8

21x +32640 -32x = 26880 . . . . . multiply by 3360

5760 = 11x . . . . . . . . . add 11x -26880

523.6 ≈ x . . . . . . . . . . divide by 11

Aidan traveled about 523.6 km by train.

What output is twice the sum of the input 3 and 4

Andreas93 [3]

Answer:

Required output = 14

Step-by-step explanation:

Sum of the input 3 and 4 = 3 + 4

Twice the sum means two times.

So, to find twice the sum of the input 3 and 4, we need to multiply the sum by 2.

2(3 + 4)

Perform the addition inside the parentheses.

2(3 + 4) = 2(7)

Now, multiply.

2(3 + 4) = 14

Hence, required output = 14
