The triangles are similar, find y

Luda [366]

Answer:

y = 3.6

x = 3.5

Step-by-step explanation:

The triangles are similar.

$\frac{3}{2.4} = \frac{x}{2.8} = \frac{4.5}{y}$

Find y:

$\frac{4.5}{y} = \frac{5}{4}$

$4.5 * 4 = 5y => 18 = 5y => y = 3.6$

Find x:

$\frac{x}{2.8} = \frac{5}{4}$

$2.8 * 5 = 4x => 14 = 4x => x = 3.5$

professor190 [17]

Answer:

$\large\boxed{k=\dfrac{2m+3}{7-r}\ \text{for}\ r\neq7}$

Step-by-step explanation:

$7k+2m=kr+4m+3\qquad\text{subtract}\ 2m\ \text{from both sides}\\\\7k+2m-2m=kr+4m-2m+3\\\\7k=kr+2m+3\qquad\text{subtract}\ kr\ \text{from both sides}\\\\7k-kr=kr-kr+2m+3\\\\7k-kr=2m+3\qquad\text{distribute}\\\\k(7-r)=2m+3\qquad\text{divide both sides by}\ (7-r)\neq0\\\\k=\dfrac{2m+3}{7-r}$
