I would have to say -0.5 then positive 0.25 because the rule seems to be divide by -2.
2/10 BECAUSE IF YOU MULTIPLY 1 AND 5 BY 2 IT IS 2/10
The total number of nails will decrease by 14 when Willa will use 7 nails on each side.
Step-by-step explanation:
Sides of one birdhouse = 7
Nails used on each side = 9
Nails used on one birdhouse = No. of sides * Nails used for each side
Nails used on one birdhouse = 7*9 = 63 nails
If she uses 7 nails on each side, then the number of nails used on each birdhouse will be;
No. of nails = 7*7 = 49 nails
Difference = Old value - New value
Difference = 63-49 = 14
The total number of nails will decrease by 14 when Willa will use 7 nails on each side.

Answer: (x, y)=(0, -6)
Step-by-step explanation:
To solve a system of equations there are usually 3 general ways.
- Elimination
- Substitution
- Augmented Matrix
Since the question is asked to use <u>elimination</u>, we are going to use it.
--------------------------------------------------------------------------------------
-5x+4y=30
2x+3y=-12
-10x+8y=60
10x+15y=-60
23y=0
y=0
------------------------------------------------------------------------------------------
Substitute the y value into any one of the equations
2x+3y=-12
2x+3(0)=-12
2x+0=-12
x=-6
Hope this helps!! :)
