Answer:

x=(-9)

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

(−2/3)(9+x)=0

(−2/3)(9)+(−2/3)(x)=0(Distribute)

−6+−2/3x=0

−2/3x−6=0

Step 2: Add 6 to both sides.

−2/3x−6+6=0+6

−2/3x=6

Step 3: Multiply both sides by 3/(-2).

(3−2)*(−2/3x)=(3−2)*(6)

x=−9

Lisa and her daughter weigh 185 pounds all together. The ratio of lisa’s weight to her daughter weight is 4:1 . How much does li

frez [133]

Since the ratio of mother to daughter is 4:1, the weight of the mother and daughter together is five times the weight of the daughter.

In fact, if the daughter weights $d$ pound, the mother weights $4d$ pounds, and the total weight is $d+4d = 5d$ .

We know that this total is 185 pounds, so we have

$5d = 185 \iff d = \dfrac{185}{5} = 37$

So, the daughter weights 37 pounds.
