Answer:

[(1/12)(5/5) + (1/20)(3/3)](x hours) = 1

(5/60 + 3/60)x = 1

(8/60)x = 1 we can reduce 8/60 by dividing out a 4

(2/15)x = 1 x both sides by 15/2

x = 15/2

x = 7 1/2 or 7.5 hours

What does x equal <br>x + 2 4/5 equals 3 1/6
docker41 [41]
X is equal to 11/30 because, using basic moves, you subtract the 2 4/5 from either side to get x by itself. So 3 1/6 - 2 4/5 = 11/30. Then you are left with x = 11/30.

Abigail orders a large 2 topping pizza for $14 and a medium 1 topping pizza for$10. If all costs of a medium pizza are 80% of a
viktelen [127]
Hello!,

FRIST :<span>  </span><span>2 topping - $14 
1 topping - $10 

1 topping is $4. (You find the difference between the two.) 
That means that a medium pizza, with no toppings is worth $6. 
So for a large plain cheese pizza - 
$6.00/10x8 [80%] 
= 2.40 
So, a large cheese pizza would cost [$6.00+$2.40] $8.40. 

I wouldn't think there would be a difference in the surcharge for a toppings. But! 
1 topping is $4. 
4/10*8=0.4 
So the large topping would cost [$4.00+$0.40] $4.40 THANK YOU!</span>

PLEASE HELP!
Citrus2011 [14]

Answer:

  f(x) = (x +6)^3 +4

Step-by-step explanation:

f(x -h) +k is the function f(x) translated by (h, k). You want to translate the function by (-6, 4), so it will be ...

  f(x +6) +4 = (x+6)^3 +4

The translated function is ...

  f(x) = (x +6)^3 +4

  f(x) = x^3 +18x^2 +108x +220 . . . . . . with parentheses eliminated

_____

The graph shows the two versions of the translated function. One is dashed so you can see the other has the same graph.
