The correct answer is 3 and any number you can really think of that equals 6
40 + 2x - 30 + x + 20 = 180
3x + 30 = 180
3x = 150
x = 50
m<B = 2x - 30
m<B = 2(50) - 30
m<B = 100 - 30
m<B = 70
Answer:
$82.3
Step-by-step explanation:
82x25=2050
2050+90=2140
2140/26=82.3
You can just do the inverse operation. 39 divied by 10 = 3.9
so 3.9 *10 =39
