Answer:
$640
Step-by-step explanation:
192 = 0.3(x)
x = 192/0.3
x = 640
The property x^axb makes it x^a+b so x^5x-2 ,
Therefore x^-10 is final
Answer:
m∠XMN = 80°
Step-by-step explanation:
you know that:
4x + 5 + 6x - 10 = 145
solve for x:
10x - 5 = 145
10x = 150
x = 15
Use this information to solve for m∠XMN
6(15) - 10
90 - 10
80
m∠XMN = 80°
It is 42. It is easy like the bottom one
1/6 is already a fraction you can't reduce it anymore
