Answer:

x = 1.75y + 0.25z

Step-by-step explanation:

Simplifying

4x + -7y = z

Solving

4x + -7y = z

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '7y' to each side of the equation.

4x + -7y + 7y = 7y + z

Combine like terms: -7y + 7y = 0

4x + 0 = 7y + z

4x = 7y + z

Divide each side by '4'.

x = 1.75y + 0.25z

Simplifying

x = 1.75y + 0.25z

The extensions of the legs AB and CD of a trapezoid ABCD intersect at point E. Find the lengths of the sides of △AED if AB=5cm,

Lynna [10]

Answer:

AE = 15 cm; ED = 18 cm; AD = 15 cm (given)

Step-by-step explanation:

ΔBEC ~ ΔAED so ...

AD/BC = AE/BE = (BE+AB)/BE = 1 + AB/BE

Substituting given numbers (lengths in centimeters), we have ...

15/10 = 1 + 5/BE

1/2 = 5/BE

BE = 10

Similarly, ...

1/2 = 6/CE

CE = 12

Then the unknown sides are ...

AE = AB + BE = 5 + 10 = 15 . . . cm

ED = CE + CD = 12 + 6 = 18 . . . cm
