Answer:
=2x+10
Step-by-step explanation:
Let's simplify step-by-step.
8x+9−(6x−1)
Distribute the Negative Sign:
=8x+9+−1(6x−1)
=8x+9+−1(6x)+(−1)(−1)
=8x+9+−6x+1
Combine Like Terms:
=8x+9+−6x+1
=(8x+−6x)+(9+1)
=2x+10
Answer:
=2x+10
Answer:
One solution: (2.5,0)
Step-by-step explanation:
We can use substitution for the solution. Substitute y=2x-5 to -8x-4y=-20 so that you end up with -8x-8x+20=-20. Next you want to add like terms which will be -16x+20=-20, next you want isolate x by subtracting 20 from both sides and leaves you with -16x=-40. Divide -16 on both sides to fully isolate x and will leave you with x=2.5. Now substiture in 2.5 for x in y=2x-5 to get y=2(2.5)-5 which will then lead to y=0.
Answer:
8
Step-by-step explanation:
$120 because the fencing of the patio would use up eight squares and each square in the picture is 3 meters so we would need 24 meters of fencing to cover up the entire patio. Since it cost $5 for one meter, 5*24 is $120.
