Answer:

$-10x+20+6x-1.2$

Step-by-step explanation:

The given expression is

$-2.5(4x-8)+1.2(5x-1)$

The missing step in the given problem is when we need to apply Distributive Property

$-2.5(4x-8)+1.2(5x-1)=-10x+20+6x-1.2$

Therefore, the right choice is B.

Remember that Distributive property is about "distributing" the outside element with each term inside the parenthesis.

Answer:

$\frac{8}{20}$

Step-by-step explanation:

We have been given that in the after school Dena, Shawn, and Amanda knit scarfs that are the same size with yellow, white, and blue yarn. Denas scarf is 2/5 yellow, Shawn's scarf is 3/5 , and Amanda's scarf is 3/4 yellow.

To make Amanda's argument true, let us compare each fraction by making a common denominator.

We can see that least common denominator of each fraction would be 20.

$\text{Dena's scarf}=\frac{2}{5}\Rightarrow\frac{2*4}{5*4}=\frac{8}{20}$

$\text{Shawn's scarf}=\frac{3}{5}\Rightarrow\frac{3*4}{5*4}=\frac{12}{20}$

$\text{Amanda's scarf}=\frac{3}{4}\Rightarrow\frac{3*5}{4*5}=\frac{15}{20}$

Since $\frac{8}{20}$ , therefore, Amanda's scarf has the most yellow.

$\\ \sf\longmapsto f(-5)$

$\\ \sf\longmapsto 5(-5)-2=-25-2=-27$

$\\ \sf\longmapsto f(-6)=5(-6)-2=-30-2=-32$
