System of Equations<br><br> y=-x-1<br> y+x=3<br><br> Solve?
ozzi
Solve by substitution

\sf{y=-x-1}
\sf{y+x=3}

Just plug in y=-x-1 into y+x=3

So we get:

\sf{(-x-1)+x=3}

Simplify that:

\sf{-1=3}

And since that is not true, that means this system of equations has no solutions!

Florence works in the shipping department of a toy factory that makes radio-controlled helicopters. Small helicopters weigh 3 ki
Damm [24]

Answer:

50 kg

Step-by-step explanation:

Given that:

SMALL HELICOPTERS:

Weight of small helicopters = 3kg

Weight of shipping container = 20kg

LARGE HELICOPTERS:

Weight of large helicopters = 4kg

Weight of shipping container = 10kg

Number of helicopters each shipping container can hold = s ; all of the packed containers will have the same shipping weight

Shipping weight :

(Weight per helicopter * number of helicopter) + weight of shipping container

Shipping weight of Small helicopters :

(3kg * s) + 20

Shipping weight Large helicopters :

(4kg * S) + 10

Shipping weight of Small helicopters = shipping weight of large helicopters

3s + 20 = 4s + 10

20 - 10 = 4s - 3s

10 = s

Hence, member of shipped helicopters = 10

Total shipping weight :

(4 * S) + 10

(4*10) + 10

40 + 10 = 50kg
