Because the two angles on the right add to 180 degrees, we can create this system:
We can also prove that
, which, when solved, shows that
.
When plugged in to the original equation, we find that y = 105 degrees.
Answer: it’s 12
Step-by-step explanation:
<u>14 packs of pencils</u> will be needed. Every 2 children use a pack and 28/2=14. Of course there are other ways to solve it too.
When the multiples of the equations in a system is added or subtracted, the resulting equation together with any of the original equation will result in the same answer.
Hence, the system of equations
x + 4y = 2
7x = 14
will also have a solution of (2, 0).
Answer:
+ 8b + 11 + 6x + 5c
Step-by-step explanation:
Split 8b + 11 + 6x + 5c
into two 2-term polynomials
+ 11 + 8b and + 6x + 5c
This partition did not result in a factorization. We'll try another one:
8b + 11 and + 6x + 5c
This partition did not result in a factorization. We'll try another one:
8b + 6x and + 11 + 5c
This partition did not result in a factorization. We'll try another one:
8b + 5c and + 6x + 11
This partition did not result in a factorization. We'll try another one:
+ 5c + 8b and + 6x + 11
This partition did not result in a factorization. We'll try another one:
+ 6x + 8b and + 11 + 5c
All three partitions failed. Tiger finds no factorization
