Answer:
1.1a+3.5b
Step-by-step explanation:
1: Solve for either x or y in one of the equations. So x + y = -1 is y = -x -1
2: substitute the new equation in the opposite equation. So x - (-x - 1) = 7
3: distribute the negative. X + x + 1 = 7
4: combine like terms. 2x + 1 = 7
5: solve for x. Subtract 1 on both sides. 2x = 6
6: divide by 2 to get x by itself. X = 3
7: plug the new value of x into one of the ORIGINAL equations. 3 + y = -1
8: solve for y. Subtract 3 on both sides.
Y = -4
9: the solution is written as (x,y) so the solution would be (3, -4)

Answer:
2 * 10^-3 oz
Step-by-step explanation:
Given that:
Number of staples per box = 6 * 10^3
Weight of staple box = 12 oz
Weight per staple = (weight of staple box / number of staples per box)
Weight per staple = 12 / 6 * 10^3
Weight per staple = 12 / 6 * 1000
= 12 / 6000
= 0.002 oz
= 2 * 10^-3 oz
