Y-5=3-9 (y+2)
Solve for y
Distribute the 9 to (y+2)
Y-5=3-9y-18
Y-5=-15-9y
+9y to both sides
10y-5=-15
+5 to both sides
10y=-10
÷10 both sides
Y= -1

2 (x-7)-10=12-4x
Solve for X
Distribute 2 to (x-7)
2x-14-10=12-4x
2x-24=12-4x
+4x to both sides
6x-24=12
+24 to both sides
6x=36
÷6 to both sides
X=6

The weight of 10 identical samples of a substance is 0.01 pound. what is the weight of 10000 samples?
Licemer1 [7]
The answer is 10 pounds.

I set up a proportion of 10 / 0.01 = 10000 / x. 

Cross-multiply to get 10x = 10000(0.01). Simplify to get 10x = 100. Divide by 10 to isolate the variable. 

x = 10. 10000 samples would weigh 10 pounds.
