Answer: 20 pieces of chocolate could be treated for 35 pieces of hard candy.

Step-by-step explanation:

Equation of direct proportion between two quantities x and y :

\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}

Put x_1=4,\ y_1=7,\ y_2=35, x_2=x

\dfrac{4}{7}=\dfrac{x}{35}\\\\\Rightarrow\ x=\dfrac{35\times4}{7}\\\\\Rightarrow\ x=20

Hence, 20 pieces of chocolate could be treated for 35 pieces of hard candy.

Answer:

\implies \dfrac{ -4x+7}{2(x-2) }

Step-by-step explanation:

The given expression to us is ,

\implies \dfrac{\frac{ 3}{x-1} -4 }{ 2 -\frac{2}{x-1}}

Now take the LCM as ( x - 1 ) and Simplify , we have ,

\implies \dfrac{\frac{ 3 -4(x-1) }{x-1} }{ \frac{2-2(2x-1)}{x-1}}

Simplifying further , we get ,

\implies \dfrac{ -4x+7}{2(x-2) }

Hence the second option is correct .

Bruno solved the following equation: 4x + one half(10x − 4) = 6 Step Work Justification 1 4x + 5x − 2 = 6 2 9x − 2 = 6 3 9x = 8
beks73 [17]

Answer:

Statement                                   Reason

1. 4x+5x-2=6                 1. Distributive Property

2. 9x-2=6                        2. Combine like terms

3. 9x=8                              3. Addition Property of Equality

4. x=\dfrac{8}{9}                               4. Division Property of Equality

Step-by-step explanation:

The given equation is

4x+\dfrac{1}{2}(10x-4)=6

Using distributive property, we get

4x+\dfrac{1}{2}(10x)+\dfrac{1}{2}(-4)=6

4x+5x-2=6

9x-2=6         (Combine like terms)

Using Addition Property of Equality, add 2 on both sides.

9x=6+2

9x=8

Using Division Property of Equality, divide both sides by 9.

x=\dfrac{8}{9}
