Answer:
1. Yes
2. No
3. Yes
Step-by-step explanation:
We have three equations where x is equal to -4. We are then asked if -4 are a solution to these equations.
To solve we need to substitute the x in every equation for -4. Start :
1.
3(2(-4) - 4) = -36
3(-8 - 4) = -36
-24 - 12 = -36
Therefore -4 is a solution.
2.
5(-4) - 6(-4) - (-4) = 18
-20 + 24 + 4 = 18
4 + 4 = 18
8 ≠ 18
Therefore -4 is not a solution.
3.
5 - 2(3(-4) - 1) = 31
5 - 2(-12 - 1) = 31
5 - 2(-13) = 31
5 + 26 = 31
Therefore -4 is a solution.
The answer to this question is Y=-9+4.

Answer:
64in
Step-by-step explanation:
first =2* second
second=2*third since the third is half of second
first =2*2*third=4*third
now lets put them all together
first+second+third=224
4*third+2*third+third=224
7*third=224 so the third part is 32
but we need the second piece
2*32=64
64 a month
12 months in a year
64 x 12 = 768
$768
