Numerator:
the product of 5 and the sum of x and y = 5(x + y)

Denominator:
the product of negative 8 and x = -8x

So the quotient:

5(x + y)
------------
- 8x

Answer is the second one.

5(x + y)
------------
- 8x

Answer:

16. $y=7x$

17. $y=0.5x$

18. $y=3x$

19. $y=2x$

Step-by-step explanation:

Equation is $y=kx$ where k is a constant of proportionality.

16.

$\frac{y}{x}=\frac{10.5}{1.5}=\frac{14}{2}=\frac{24.5}{3.5}=\frac{35}{5}=7$

So, equation is $y=7x$

17.

$\frac{y}{x}=\frac{1}{2}=\frac{2}{4}=\frac{2.5}{5}=\frac{3.5}{7}=\frac{1}{2}=0.5$

Equation is $y=0.5x$

18.

$\frac{y}{x}=\frac{6}{2}=\frac{9}{3}=\frac{15}{5}=\frac{18}{6}=3$

Equation is $y=3x$

19.

$\frac{y}{x}=\frac{4}{2}=\frac{8}{4}=\frac{14}{7}=\frac{18}{9}=2$

Equation is $y=2x$

Two sides of a triangle have lengths 10 and 18. Which inequalities describe the possible lengths for the third side x?

puteri [66]

Let with X is denoted the length of the third side.
For a triangle the following statements must be true:
The sum of the lengths of any two sides of a triangle is greater than the length of the third side.
This means that this inequality can be written: X<10+18 ,X<28
