Answer: =80/11

Step-by-step explanation:x=80-10x

We move all terms to the left:

x-(80-10x)=0

We add all the numbers together, and all the variables

x-(-10x+80)=0

We get rid of parentheses

x+10x-80=0

We add all the numbers together, and all the variables

11x-80=0

We move all terms containing x to the left, all other terms to the right

11x=80

x=80/11

x=7+3/11

Is 7/8 or 11/10 closer to 1? How did you decide anybody help please?

erik [133]

Let

A-----> $\frac{7}{8}$

B-----> $\frac{11}{10}$

C-----> $1$

we know that

Point A-------> Multiply numerator and denominator by $10$

$\frac{7*10}{8*10} =\frac{70}{80}$

Point B-------> Multiply numerator and denominator by $8$

$\frac{11*8}{10*8} =\frac{88}{80}$

Point C-------> Multiply numerator and denominator by $80$

$\frac{1*80}{1*80} =\frac{80}{80}$

Find the distance Point A to Point C

$\frac{80}{80} -\frac{70}{80} =\frac{10}{80}$

Find the distance Point B to Point C

$\frac{88}{80} -\frac{80}{80} =\frac{8}{80}$

therefore

$\frac{8}{80} < \frac{10}{80}$

Point B is closer to Point C

$\frac{11}{10}$ is closer to $1$

the answer is

$\frac{11}{10}$ is closer to $1$

Sin(angle) = opposite leg / hypotenuse

Sin(45) = Opposite leg / 28

Opposite Leg = 28 * Sin(45)

Opposite Leg = 14 SQRT(2) = 19.8
