The answer should be 90.8 because when you add up all the temp. you get 454 then you divide by # of days which is five 
hope this helps :)
        
                    
             
        
        
        
Answer:
-16x-28
Step-by-step explanation:
Break it into little pieces; start with distributing the -7:
-7(5+x)
-35-7x
Now add the rest of the problem: 7-35-7x-9x
Combine like terms: 7-35               7x-9x
7-35=-28             7x-9x=-16x
Rearrange so the coefficient and variable are upfront, giving you:
-16x-28
 
        
             
        
        
        
Reason:
1. Given
2. Angles opposite by the vertex
3. Two pair of corresponding angles are congruent (∠C ≅∠E and <span>∠ABC≅∠DBE)</span>
        
                    
             
        
        
        
Answer:
θ ≈ 71.6°
Step-by-step explanation:
The angle between two lines with slopes m₁ and m₂ is:
tan θ = | (m₂ − m₁) / (1 + m₁m₂) |
Here, m₁ = -2 and m₂ = 1.
tan θ = | (1 − (-2)) / (1 + (-2)(1)) |
tan θ = | 3 / -1 |
tan θ = 3
θ ≈ 71.6°
 
        
             
        
        
        
<u>Equation/Question:</u>
Solve for b. 3(b + -2)-8=-5 what is the answer?
<u>Answer/Steps to answer:</u>
1.Simplify  b+-2 to b−2.
3(b−2)−8=−5
2. Add 8 to both sides.
3(b-2)=-5+8
3. Simplify  -5+8  to  3.
3(b-2)=3
4. Divide both sides by 3.
b-2=1
5. Add 2 to both sides.
b=1+2
6. Simplify  1+2 to 3.
b=3
