Hey there!
4x - 16 + 2x + 16 = 180 (linear pair)
4x + 2x - 16 + 16 = 180
6x = 180
x = 180/6
<u>x </u><u>=</u><u> </u><u>3</u><u>0</u><u>.</u>
Hope it helps ya!
Answer:$104.5
Step-by-step explanation:
cats=c
Dogs=d
2c+3d=455
d=82
Substitute d=82 in 2c+3d=455
2c+3(82)=455
2c+246=455
Collect like terms
2c=455-246
2c=209
Divide both sides by 2
2c/2=209/2
c=104.5
1 cat cost $104.5
