Answer:

Weight on the moon = 43.60 l b

Step-by-step explanation:

Let the weight of the object on the moon be M.

Let the weight of the object on the earth be E.

M α E

M = kE (where k = constant)

Make k the subject of the formula.

k = M/E

When M = 25.46 l b and E = 149.76 l b

k = 25.46/149.76

k = 0.17

Put k = 0.17 into the equation M = kE

Therefore;

M = 0.17E ( This shows the relationship between M and E)

When E = 256.47 l b

M = 0.17 * 256.47

M = 43.60 l b

9x+5y=8<br> 3x–y=4<br> what is the y-value of the solution to the system?
CaHeK987 [17]

Answer:

y=7.51

Step-by-step explanation:

First, you have to simplify one of the equations down

3x-y=4

y=-4+3x

Second, you insert the value of y into the other equation and then solve for x

9x+5(-4+3x)=8

9x-20+15x=8

24x=28

x=1.17

Last, insert the value of x into the original equation and then solve for y

y=4+3(1.17)

y=7.51
