The error is in the second step they subtracted 3 from both sides but it was a 3x, which you can not do.
Correction.
9x+18+3x=1
12x+18=1
12x=-17
x=-17/12

Answer:

error is in second step.

Step-by-step explanation:

The given equation is 9x + 18 + 3x = 1

Now we will solve this equation and compare it with the given answer.

9x + 18 + 3x = 1

12x + 18 = 1

12x = (-17)

x = $(\frac{-17}{12})$

Now we find the error is in second step.

it takes 21 minutes for 5 people to paint 7 walls. how many minutes does it take 3 people to paint 10 walls

tensa zangetsu [6.8K]

21/7=3mins per wall with 5 people.
Because we assume that all of the people paint at the same rate, 3 X 5=15 mins for one person working alone.
15/3=5 mins per wall with 3 people X 10 people= 50 mins for 3 people to paint 10 walls.

The answer is 50 mins.

8.4.49 A cow is tethered to one corner of a square barn, 19 feet by 19 feet, with a rope 160 feet long. (See the illustration

SashulF [63]

Answer:

$20096 ft^2$

Step-by-step explanation:

We are given that

Length of rope=l=160 feet

Radius of quadrant of circle=r=160 feet

We have to find the maximum grazing area of the cow.

We know that

Area of quadrant of circle= $\frac{1}{4}\pi r^2$

Where $\pi=3.14$

Using the formula

Area grazed by cow= $\frac{1}{4}\times 3.14(160)^2$

Area grazed by cow= $20096 ft^2$
