Answer:

-14 =a

-9 = b

-12 = c

Step-by-step explanation:

In matrix addition we add the corresponding elements to make equations

-10 +-4 = a

-14 =a

3 + -12 = b

-9 = b

-9 + -3 = c

-12 = c

Using the following diagram, solve for x. Show work

Alex17521 [72]

Answer:

x = 7.5

Step-by-step explanation:

A line parallel to a side of a triangle and intersecting the other 2 sides, divides those sides proportionally, that is

$\frac{8}{10}$ = $\frac{6}{x}$ ( cross- multiply )

8x = 60 ( divide both sides by 8 )

x = $\frac{60}{8}$ = 7.5
