Answer:
So first you do $0.50 x 3 = 1.5
then you add that to $12.00
$12.00 + 1.5 = 13.5
13.5 is the cost of one pizza.
Since they bought 12:
The total cost of the 12 pizza is $162 <== not important
<u>13.5 divided by 8 is 1.687</u>
<u>round 1.56875 to the nearest cent 1.7 = $2</u>
so each slice costs $2
Answer:
1. 2x-20
2. 4(x+3)
Step-by-step explanation:
Answer:
The number of bags used is 2 bags
Step-by-step explanation:
The mass of the jellybeans in the jar = 2 lbs
The mass divided evenly into bags = 1 pound each
Therefore the operation applied to the jar of jellybean is a division by 1 lb/bag, therefore, we have;
The number of bags used = 2 lbs/(1 lb/bag) = 2 bags
Answer:
The third option is correct.
The domain of the function is given by

The range of the function is given by

Step-by-step explanation:
Sara bought a cell phone for $200 and its value has decreased at rate of $5 per month.
V(t) is the value of the phone and t is the number of months.
The domain of the function is the possible values of the number of months t.
The domain of the function is given by

The range of the function is the values of V(t) that we get after substituting the possible values of the number of months t.
The range of the function is given by

When the number of months is t = 0 then the value of the function is maximum V(t) = 200
When the number of months is t = 40 then the value of the function is minimum V(t) = 0
Therefore, the third option is correct.
Answer:
u=2/2a-1
Step-by-step explanation:
a=1/u +1/2
you find the LCM first which is 2u
a=2+u/2u
cross multiply
2au=2+u
subtract u from both sides
2au-u=2
u is common to the right hand side
u(2a-1)=2
divide through by 2a-1
u=2/2a-1
