Ametorite found in the united states weighs 7/10 as much as one found in mongolia. the meteorite found in mongolia weighs 22 tons. how much does the one in the united states weigh?

The weight of meteorite found in United States is 15.4 tons

Step-by-step explanation:

Given as :

A meteorite found in the United States weighs 7/10 as much as one found in Mongolia .

The weight of meteorite found in Mongolia = x = 22 tons

Let The weight of meteorite found in United States = y

∵The weight of meteorite found in United States = × weight of meteorite found in Mongolia

i.e y =   × x

Or, y =   × 22 tons

Or, y =

Or, y =

∴  y =

i.e y = 15.4 tons

So, The weight of meteorite found in United States = y = 15.4 tons

Hence, The weight of meteorite found in United States is 15.4 tons Answer

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
