Let the number of packages of hot dogs be D, and the number of packages of hamburgers be H. We can set up the equations:
1.60D + 5H = 23
D + H = 8 ---> which we can subtract D on both sides and get: H = 8 - D
1.6D + 40 - 5D = 23, -3.4D = -17, D = 5. The number of packages of hot dogs we buy are 5.
Now, we plug that into D + H = 8, and get 5 + H = 8. Subtracting by 5 on both sides of the equation, we get H = 3. So the number of packages of hamburgers we buy are 3.

Answer:
<h3>5ths</h3>
Step-by-step explanation:
Given that:
- Price of whole pizza (A) = 5 × 3 = $15
- Price of whole pizza (B) = 4.50 × 5 = $22.50
They make 8 whole pizzas.
Therefore
- Thirds (A) = 15 × 8 = $120
- Fifths (B) = 22.50 × 8 = $180
They'll make more money if they slice it into fifths.
180 - 120 = $60
Because if they slice it into thirds, total profit will be $60 less

Answer: y = 54(1.06)^t
Step-by-step explanation:
It is estimated that the population of bacteria will increase by 6% each hour. This is an exponential growth. The formula for determining exponential growth is expressed as
y = b(1 + r)^ t
Where
y represents the population after t years.
t represents the number of years.
b represents the initial population.
r represents rate of growth.
From the information given,
b = 54
r = 6% = 6/100 = 0.06
Therefore, the formula for the population of bacteria is
y = 54(1 + 0.06)^t
y = 54(1.06)^t
-2(4g-3)= 30
-8g+6= 30
-8g=30-6
-8g= 24
G= 24/-8
G= -3
