9/2{8-x}+36=102-5/2{3x+24}
you first use 9/2 to open brackets
9/2*8=36,
9/2*x=9/2x
36-9/2x=102-5/2{3x+24}
5/2*3x=15/2x+60
36-9/2x=-15/2x-60
36+60=15/2x+9/2x
96=12x you then divide and the answer obtained will be 8.
x=8
I think it's b but i'm not sure!
Answer:
( 5 - 2t ) < - 4
Step-by-step explanation:
The midnight temperature is 5 °C and the temperature is decreasing at the rate of 2°C per hour.
If t is the hours past midnight then after t hours the temperature will be ( 5 - 2t ).
Now, if this temperature is colder than - 4° C, then the inequality can be written as ( 5 - 2t ) < - 4 (Answer)
<h2>
Hello!</h2>
The answer is:
The correct option is:
B) 15
<h2>
Why?</h2>
To solve the problem, we need to use the Pythahorean Theorem. We know that we can use the theorem since we are working with a right triangle as we can see in the picture.
So, we are given the following information:

Now, using the Pythagorean Theorem, we have:

Hence, we have that the correct option is:
B) 15
Have a nice day!
