Please help me ive never done one like this

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.

Answer:

The answer is 17 to 16

Step-by-step explanation:

Because the if you add the kids who make food you get 170 and if you add the children who dont make food you get 160.

So.

170 to 160

you see what number they have in common and divide it by each.

170 divided by 10= 17

160 divided by 10= 16

our answer is: Ratio: 17 to 16
