Answer:
x=7
Step-by-step explanation:
4(x-8)= -2(x-5)
4x+32= -2x+10
+2x +2x
6x-32=10
+32 +32
6x= 42
divide by 6 on both sides
x=7

Answer:
3/8
Step-by-step explanation:
1- 1/4 +(1/2 x 3/4)
1. subtract 1/4 to get 3/4 (how much time she has left in class).
2. multiply 3/4 by 1/2 to find how much half of 3/4 is.
3. Half of 3/4 is 3/8 so that's how much time she spent on the balance beam.
The answer is 3.1 because 4 is under 5
Answer:
The temperature at the start is 35F
The temperature of the room is 74F
<em></em>
Step-by-step explanation:
Given

Solving (a): The temperature at the start.
To do this, we set: 
So, we have:




<em>Hence, the temperature at the start is 35F</em>
<em></em>
Solving (b): The room temperature
We have:

To get the temperature of the room, we simply remove the exponential function.
So, we have:

<em>Hence, the temperature of the room is 74F</em>
