Answer:

x=1,y=3

correct answer is (1,3)

Step-by-step explanation:

We can quickly eliminate y by subtracting one equation from the other

(-2x+y=1)-(-4x+y=-1)

2x=2

x=1

plug x=1 into equation 1

-2(1)+y=1

y=1+2=3

Answer:

8 lb of flounder at $2.50/lb

4 lb of shrimp at $5.00/lb

Step-by-step explanation:

Let A be the pounds of shrimp

Let B be the pounds of flounder

Let C be the cost per pound of flounder

A + B = 12

A = 12 - B

        BC = 20

    A(2C) = 20

BC =  A(2C)

BC =  (12 - B)(2C)

BC =  24C - 2BC

3BC =  24C

  3B =  24

    B = 8 lb

A + 8 = 12

    A = 4 lb

Suppose x represents an objects weight on Earth. Write two expressions: one that you can use to find the objects weight on Mars
tatyana61 [14]
The weight of an object is the product of its mass and the acceleration of gravity.
If g[e] is the acceleration of gravity on earth, and g[M] the same for Mars and g[m] the same for the moon,
then m[M]=m[e]g[M]/g[e] and m[m]=m[e]g[m]/g[e] where m[ ] denotes mass. Note that weight=mg (measured in newtons) while mass is in kilograms.
If g[M]=g[e]/3 and g[m]=g[e]/6 approximately. Then the weight of an object on Mars will be about a third of what it is on earth, while on the moon it would be about a sixth of what it is on earth.
