Answer:
y=11
x=-4
Step-by-step explanation:
y =-x+7
2x-5y=-7
insert the first equation into the second like so...
2x+5x-35=-7
Now rearrange...
2x+5x=-7+35
Now solve...
7x=-28
x=-4
Now incert x in any equation...
y=4+7
y=11
Yes that answer is right.
Answer:
Its 255+x=180 => so x=105
Answer:
the answer is 50 degrees
Step-by-step explanation:
the sum of all three angles of a triangle is always 180 degrees.
first you have to combine all terms, equal it to 180, and then solve for x.
4x-20+2x+2x=180
8x-20=180
8x=200
x=25
then to find angle G you multiple x times 2 (2x)
2 × 25 = 50
