Lös för x 7x + 60 = 5x + 120 *

x = 30

Step-by-step explanation:

We are to solve the equation  7x + 60 = 5x + 120 for x.

Start by grouping like terms together.  The x terms go on the left and the constants on the right:

7x - 5x = 120 - 60

This simplifies to 2x = 60.

Dividing both sides by 2, we get x = 30

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
