Step-by-step explanation:

Because the trapezoid is isosceles, the two diagonals are congruent. This can be shown by ASA.

ACD = BDC Properties of parallel lines.

DC = DC A line is equal to itself

DBA = CAB Property of parallel lines.

AC = DB Parts of Congruent triangles are congruent

3x + 15 = 7x - 9 Add 9 to both sides

3x + 15 + 9 = 7x

3x + 24 = 7x Subtract 3x from both sides.

24 = 7x - 3x

24 = 4x Divide by 4

24/4 = 4x/4

x = 6

Ria can paint a room in 4 hours. Destiny can paint the same room in 6 hours. How long would it take Ria and Destiny to paint the

Lerok [7]

Time taken by Ria to paint a room = 4 hours

Time taken by Destiny to paint a room = 6 hours

If they work together, they complete 1 job. So,

$\frac{1x}{4}+\frac{1x}{6}=1$

The LCD of 4 and 6 is 12

$\frac{3x+2x}{12}=1$

$\frac{5x}{12}=1$

$5x=12$

$x=\frac{12}{5}$

Hence, both of them can paint the room in $\frac{12}{5}$ hours or 2.4 hours.
