Please help me!<br> Find WX.

Fynjy0 [20]

So WX is 7y +4 and XY is 21, and when you add those lines you get the whole thing, which is 12y so write that like an equation
12y = 7y+4+21
12y = 7y+25
5y = 25
y = 5

Lisa is 10 cm taller than her friend ian. Ian is 14 cm taller than jim. Every month, their heights increase by 2 cm. In 7 months

koban [17]

Answer: Ian's height = x+14 = 69+14 = 83 cm

Explanation :

Let the height of Jim be x

Let the height of Ian be x+4

Let the height of Lisa be x+4+10=x+14

Since their heights increase by 2cm every months

so after 7 months ,

Jim's height = x+14

Ian's height= x+4+14=x+18

Lisa's height= x+14+14=x+28

According to question,

Sum of Ian's and Jim's height = 170cm

$x+18+x+14 = 170\\2x+32 =170\\2x =170-32\\2x = 138$

⇒x = $\frac{138}{2}$

⇒ x= 69cm

∴ Ian's height = x+14 = 69+14 = 83 cm
