Answer:

x = 4

Step-by-step explanation:

Corresponding segments of similar triangles are proportional. Here, the similar triangles are ...

ΔABC ~ ΔADE

so the relationship between the sides is ...

BC/BA = DE/DA . . . . . . we put the unknown value in the numerator

x/4 = 12/(4+8)

x = 4(1) = 4

Y-x=4 and x is three times the value of y, what is the value of x+y?

slega [8]

Answer:

x+y=-8

Step-by-step explanation:

y-x=4

x=3y

y-3y=4

x=3y

-2y=4

x=3y

y=4/(-2)

x=3y

y=-2

x=3*(-2)

x=-6, y=-2 then

x+y=-6-2=-8

1 7/10 x 2/3 what is the product

Ludmilka [50]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{1 \frac{2}{15}}}}}}$

Step-by-step explanation:

$\sf{1 \frac{7}{10} \times \frac{2}{3} }$

Convert the mixed number into improper fraction

$\longrightarrow{ \sf{ \frac{10 \times 1 + 7}{10} \times \frac{2}{3}}}$

$\longrightarrow{ \sf{ \frac{17}{10} \times \frac{2}{3}}}$

To multiply one fraction by another, multiply the numerators for the numerator, and multiply the denominator for its denominator and reduce the fraction obtained after multiplication into lowest term

$\longrightarrow{ \sf{ \frac{17 \times 2}{10 \times 3}}}$

$\longrightarrow{ \sf{ \frac{34}{30}}}$

$\longrightarrow{ \sf{ \frac{17}{15} }}$

Convert the improper fraction into mixed number

$\longrightarrow{ \sf{1 \frac{2}{15} }}$

Hope I helped!

Best regards! :D
