it would be 16 cause 7.2+9.6= 15.8
Answer:
70 different meals
Step-by-step explanation:
A menu offers a choice of 2 salads, 7 main dishes, and 5 desserts
There are 3 types of choices are given
each one have different choices. we need to select one salad, one main dish and one dessert
To find the number of different meals we multiply the different choices

so 70 different meals
Ok, first set this up as an equation with your given variables. You know that Sylvie bought 1 container of cream cheese, which is $2.95, and you know that Sylvie spent $7.50
<u>(my best assumption is this is the subtotal)</u><u /> on the cream cheese and 13 bagels. As an equation, it would come out as:

To start solving the algebraic equation, wou can subtract 2.95 on both sides, resulting as

Now, to get "b" by itself, you must divide
13 on both sides, resulting as

This will answer your question as the cost of 1 bagel would be
$0.35 per bagel.
<span> half life i= 78 hours
amount after 78 hours is 395 kg:
395 = 790e^(k*78)
Dividing by 790 and taking natural log
ln (395/790) = (k*78)
-0.6931 = 78k
-0.00888 = k
lets calculate how much is left after 18 hours:
Amount(18)
= 790e^(-0.00888*18)
Amount = 673.301 kg
hope this helps</span>
The answer to your question is 9.5
