Answer:

Step-by-step explanation:

3/4x=15 you flip 3/4 to 4/3 and cancel it out on one side leaving x by itself then you multiply 4/3 by 15 and you get 60/3 and that equals 20 x=20

Answer:

9 grams

Step-by-step explanation:

<u>We can use these equations</u>:

y = ax

Here we know that y = 1800 and a = 2, so we will need to solve for x

Solving for x we get $x= \frac{y}{a}$ and plugging in our known values we get $x = \frac{1800}{2}$ and this simplifies to 900
This means one serving contains 900 mg of baking soda

We can now change the equation to solve for the total amount of baking soda required to serve 10 people

We know that a = 10 and x = 900
The equation is already solved for y, so plugging in our new values we have y = (10)(900) = 9000 mg
The recipe will require 9000 mg in order to serve 10 people

Now there are 1000 mg in 1 g, so converting mg to g we have 9000 mg is equivalent to 9 grams
