Step-by-step explanation:
i dont know
felling sorry
First you would distribute the -3
-3x+1+7x=27
Combine like terms
4x+1= 27
Minus 1 on both sides
4x= 26
Divide by 4
X= 6.5
Answer:
3. adjacent; 49
4. adjacent; 71
5. verticle; 41
6. adjacent; 14
Step-by-step explanation:
ok basically if the angles are next to each other, then they're adjacent and if they're across from eachother they're verticle.
to find 3:
set both equations equal to each other and solve because verticle angles are equal
to find 4:
add the 2 equations together and set it equal to 180 because adjacent angles add up to equal either a complementary angle or supplementary depending on the problem
3(x-4)(2x-3)=0
(x-4)(2x-3)=0
x=4
x=3/2
Answer: 13
