1. This equation shows how the total number of appetizer recipes Carly knows depends on the number of weeks she attends culinary school. a = 2w. The variable w represents the number of weeks she has attended culinary school, and the variable a represents the total number of appetizer recipes she knows. After how many weeks of culinary school will Carly know a total of 8 appetizer recipes? *
Answer:
16 weeks
Step-by-step explanation:
Set up a proportion with the equation.
a = 2w
8
2 x 8= 16 then 16/1=16
so she was at school for 16 weeks.

please help im super behind and trying to get caught up
Answer:
x = -9
Step-by-step explanation:
multiply 2 on both sides which cancels out the 2 in the fraction and then do -1 times 2 and 2 times x (which is just 2x). After doing that your equation should look like 3x + 7 = 2x - 2
Collect your like terms (the numbers with an x variable go togther and the ones with an x have to be together) and rearrange it so it looks like: 3x - 2x = -2 - 7 after you have this written subtract 3 from 2 now because they're on the same side which leaves you with x (usually we leave out the one because it doesn't make a difference) so now you're left with x = -2 - 7 for this step subract -2 from 7 which leaves you with x = -9
Steps:
3x + 7 = 2x - 2
3x - 2x = -2 -7
x = -2 - 7
x = -9

Step-by-step explanation:
For lunch, a restaurant discounts prices on their menu by 15% and then applies a
10% sales tax to the discounted price. If Jade pays $18.70 after the discount and
sales tax are applied, what was the price of Jade's lunch on the menu?
A $17.48
B $19.35
C $19.68
D $20.00
Answer:
It would be D
Step-by-step explanation:
If you do the problem backward and apply the discount and taxes to 20$, then you get 18.70
The price of Jade's lunch on the menu will be;
⇒ $17.05
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
For lunch, a restaurant discounts prices on their menu by 15% and then applies a 10% sales tax to the discounted price.
And, Jade pays $18.70 after the discount and sales tax are applied.
Now,
Let the price of Jade's lunch on the menu = x
Since, A restaurant discounts prices on their menu by 15%.
Hence, The discounted price = x - 15x/100
And, Then applies a 10% sales tax to the discounted price.
Hence, The price = 10% of (x - 15x/100) + x
= 10/100 × 85x/100 + x
= 850x/10000 + x
= 17x/200 + x
= 217x/200
Since, Jade pays $18.70 after the discount and sales tax are applied.
Hence, We get;
⇒ 217x / 200 = 18.50
⇒ x = $17.05
Thus, The price of Jade's lunch on the menu will be;
⇒ $17.05

The Collatz conjecture is one of the most famous unsolved mathematical problems, because it's so simple, you can explain it to a primary-school-aged kid, and they'll probably be intrigued enough to try and find the answer for themselves.
Hi, you've asked an incomplete question. However, I inferred you need a brief explanation about The Collatz conjecture.
Explanation:
Put simply, what the Collatz conjecture unsolved problem entails is that if any positive number is picked and it is:
An even number (eg 2, 4, 6,...), then if they are divided by 2, the new number gotten should undergo the same process (that is to be divided by 2), it is believed your calculation would finally end up at 1. For example, let's pick the number 6, (6÷2=4; repeating the process 4÷2=1)An odd number, then if they are multiplied by 3 and 1 is added to the result, it is believed that your calculation would finally end up at 1.Need help ASAP!

A tanker truck fills the gas station's reservoir at the rate of 1212 gallons per minute. If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir? Round your answer to the nearest tenth. Enter your answer in the box.
Answer:
2.9 minutes
Step-by-step explanation:
Given
[tex]Rate = 12 gallon/minute[/tex]
[tex]Size = 35\ gallon[/tex]
Required
Determine the time spent
The rate is a ratio of size to time
So, it can be expressed as:
[tex]Rate = \frac{Size}{Time}[/tex]
Substitute values for Rate and Size
[tex]12 = \frac{35}{Time}[/tex]
Cross Multiply
[tex]12 * Time = 35[/tex]
Solve for Time
[tex]Time = 35/12[/tex]
[tex]Time = 2.9[/tex] (approximated)
