The answer is the slope of XV is 1.

The slope of UW is -1

The slopes of the diagonals are negative reciprocals

Denver gets 5/19 of the dog food.

natka813 [3]

Answer:

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

Step-by-step explanation:

If Denver gets $\frac{5}{19}$ of the dog food, then Engle and Fido share $\frac{14}{19}$ of the dog food. If Fido have $x$ of the dog food, then Engle have $\frac{4}{3}\cdot x$ such that:

$x + \frac{4}{3}\cdot x = \frac{14}{19}$

$\frac{5}{3}\cdot x = \frac{14}{19}$

$x = \frac{42}{95}$

Fido have $\frac{42}{95}$ of the dog food (44.211 %), Engle have $\frac{28}{95}$ of the dog food (29.474 %) and Denver have $\frac{5}{19}$ of the dog food (26.316 %).

Richard and Teo have a combined age of 26 . Richard is5 years older than twice Teo's age. How old are Richard and Teo?

loris [4]

Answer:Teo's age = 7 years ,Richard's age = 19 years

Step-by-step explanation:

Step 1

Let Teo's age be represented as x

Such that Richard 's age = 5 + 2x

and their combined ages equaling 26 can be expressed as

x + 5+ 2x = 26

Step 2 --- SOLVING

x + 5+ 2x = 26

3x+ 5= 26

3x= 26-5

3x= 21

x = 21/3

x = 7

Teo's age = 7 years

Richard's age = 5+2x= 5 + 14= 19 years
