Given:

DE = (6x - 9) cm

EF = (4x + 4) cm

LM = 14 cm

MN = 16 cm

To find:

The value of x.

Solution:

<em>If three or more parallel lines intersect two transversals, then they cut off the transversals proportionally.</em>

$$\Rightarrow \frac{DE}{EF} =\frac{LM}{MN}$

$$\Rightarrow \frac{6x-9}{4x+4} =\frac{14}{16}$

Do cross multiplication.

$$\Rightarrow 16( {6x-9})=14 ({4x+4} )$

$$\Rightarrow 96x-144=56 x+56$

Add 144 on both sides.

$$\Rightarrow 96x-144+144=56 x+56+144$

$$\Rightarrow 96x=56 x+200$

Subtract 56x from both sides.

$$\Rightarrow 96x-56x=56 x+200-56x$

$$\Rightarrow 40x=200$

Divide by 40 on both sides, we get

$$\Rightarrow x=5$

The value of x is 5.

Chang made $156 for 13 hours of work at the same rate, how many hours would he have to work to make $108?

sdas [7]

Answer:

9 hours

Step-by-step explanation:

"At the same rate" means time and wages are proportional.

time/wages = t/$108 = (13 h)/$156

t = 108(13 h)/156 . . . . . . . . . . . . . . . units of dollars cancel

t = 9 h

Chang would have to work 9 hours to make $108.
