Answer:

Let's solve for a.

2(3x+4)=ax+b

Step 1: Flip the equation.

ax+b=6x+8

Step 2: Add -b to both sides.

ax+b+−b=6x+8+−b

ax=−b+6x+8

Step 3: Divide both sides by x.

−b+6x+8

Each of the 10 students in the baking club made 2 chocolate cakes for a fundraiser. They all used the same recipe, using C cups

8090 [49]

Answer:

The expression is C/20 cups of flour in one cake

Step-by-step explanation:

* Lets explain how to solve the problem

- There are 10 students

- Each one made 2 chocolate cakes

- They all used the same recipe

- The total amount of flour is C cups

* Lets change these information to equation

∵ There are 10 students

∵ Each student made 2 cakes

∴ The total number of cakes = 10 × 2 = 20 cakes

∵ The total amount of flour for the twenty cakes is C cups

- To find the amount of flour in each cake divide the total amount

of flour by the total number of the cakes

∴ The amount of flour in each cake = C/20

* The expression is C/20 cups of flour in one cake

Answer:

There are 240 boys.

Step-by-step explanation:

There are five boys to every three girls in an introductory Chinese course. Given that there are 384 students enrolled in total, we want to determine the amount of students which are boys.

Let b represent the number of boys and g girls.

Since the ratio is 5:3, we can write that:

$\displaystyle \frac{5}{3} = \frac{b}{g}$

And since the total number of students is 384:

$b + g = 384$

From the first equation, cross-multiply:

$5g = 3b$

Solve for g:

$\displaystyle g = \frac{3}{5} b$

Substitute:

$\displaystyle b + \left (\frac{3}{5} b\right) = 384$

Simplify:

$\displaystyle \frac{8}{5} b = 384$

Solve for b:

$\displaystyle b = \frac{5}{8}\left(384\right) = 240$

In conclusion, 240 of the total students are boys.
