If 6:2=8:x, then a. 6x = 16 b. 6x = 10 c. 2x = 48 d. 2x = 14

stellarik [79]

Answer:

6x = 16

Step-by-step explanation:

Given:

$\displaystyle \large{6:2 = 8:x}$

The equation can be rewritten as:

$\displaystyle \large{\dfrac{6}{2}=\dfrac{8}{x}}$

Multiply both sides by 2x.

$\displaystyle \large{\dfrac{6}{2}\cdot 2x=\dfrac{8}{x}\cdot 2x}$

Simplify the equation in simplest form.

$\displaystyle \large{6x=8\cdot 2}\\\\\displaystyle \large{6x=16}$

Therefore, the answer to this question is 6x = 16.

Eugene walked all the way to school at 3 mph then realized she forgot her math book (how could she?!), so she ran back at 7 mph.

Fynjy0 [20]

$\text{Answer: }1\frac{23}{40}\ miles\text{ far she live from school.}$

Explanation:

Since we have given that

Speed at which Eugene walked all the way to school = 3 mph

After realizing that she forgot her math book, she ran back

Speed at which Eugene walked back to her house = 7 mph

Let the distance between her house and her school be x

According to question,

$\frac{x}{3}+\frac{x}{7}=\frac{45}{60}\\\\\frac{7x+3x}{21}=\frac{3}{4}\\\\\frac{10x}{21}=\frac{3}{4}\\\\x=\frac{3\times 63}{4\times 10}=\frac{63}{40}=1\frac{23}{40}\ miles.$

Hence,

$1\frac{23}{40}\ miles\text{ far she live from school.}$
