Answer:
x=5.2
Step-by-step explanation:
8x−14=7.7x+3x
Step 1: Simplify both sides of the equation.
8x−14=7.7x+3x
8x+−14=7.7x+3x
8x−14=(7.7x+3x)(Combine Like Terms)
8x−14=10.7x
8x−14=10.7x
Step 2: Subtract 10.7x from both sides.
8x−14−10.7x=10.7x−10.7x
−2.7x−14=0
Step 3: Add 14 to both sides.
−2.7x−14+14=0+14
−2.7x=14
Step 4: Divide both sides by -2.7.
−2.7x
/−2.7 =
14
/−2.7
x=−5.185185 or 5.2
Just divide by 12 because they're are 12 inches in a foot. 240 ÷ 12 = 20
Answer:
length=30 ft breadth=20 ft
Step-by-step explanation:
let lenght be x then breadth will be 2/3x
now, area=lenght×breadth
=>600 =(x×2/3x)
=>600=2/3x^2
=>x^2=900
=>x=30 (ft)
now length will be 30 ft
breadth will be 30×2/3 (ft) =20(ft) ✌️
