$\rm \looparrowright - \frac{1}{4} (8 - 4 + 20x)$

Subtract the numbers

$\rm \looparrowright - \frac{1}{4} (4+ 20x)$

Factor out 4 from the expression

$\rm \looparrowright - \frac{1}{ \cancel4} \times \cancel4(1 + 5x)$

$\rm \looparrowright - (1 + 5x)$

When there is a - in front of an expression in parentheses, change the sign of each term in the expression to -

$\rm \looparrowright - 1 - 5x$

<em>Thus, Options A and F are correct!!~</em>

HELP ASAP!!! I SUCK AT MATH AND I DON’T understand this!!!

Answer:

Part A:

$\frac{13}{20}$

Part B:

$\frac{1}{39}$

Step-by-step explanation:

The total number of candies is 40.

10 + 14 + 4 + 12 = 40

14 are Butterfinger and 12 are Crunch.

14 + 12 = 26

$\frac{26}{40}$

$\frac{26}{40}=\frac{26/2}{40/2}=\frac{13}{20}$

$\frac{10}{40} =\frac{10/10}{40/10} =\frac{1}{4}$

40 - 1 = 39

$\frac{4}{39}$

$\frac{1}{4}$ × $\frac{4}{39}$

$\frac{1}{39}$
