Answer:
391,660.6
Step-by-step explanation:
First we need to do what is in the parentheses. 56/23 equals 2.4. 4234 + 2.4 is 4236.4... 4236.4 times 94 is 398,221.6... Now 9 to the fourth power is 6561. x + 6561 is 398,221.6 so x equals 391,660.6... I hope this helps and please make me the brainliest. Thanks!

Answer:
x= -4 & y=-12
Step-by-step explanation:
multiply y=3x by 2
giving you 2y=6x
subtracting 2y=x+20 from 2y =6x
=> 5x=-20
dividing through by 5
=> x=-4
put x=-4 into y=3x
=> y=3(-4)
<em>y</em><em>=</em><em>-12</em>
Answer:
Step-by-step explanation:
Given
at 9 am temperature of the body is 
1 hr later temperature 
Temperature of room 
According to newtons law
