Solve for x: the quantity of x plus 16 all over 3 = 3x (1 point) x = −7 x = −13 x = 8 x = 2
Hatshy [7]
<h2>The required value of x is equal to 2.</h2>

Step-by-step explanation:

We have,

\dfrac{x+16}{3}=3x

To find, the value of x in the given equation = ?

∴ \dfrac{x+16}{3}=3x

By crossmultiplication, we get

3(3x) = x + 16

⇒ 9x = x + 16

⇒  9x - x = 16

⇒  8x = 16

⇒  x = \dfrac{16}{8}

⇒  x = 2

∴ The value of x = 2

Thus, the required value of x is equal to 2.

The amount of time it takes p people to paint d doors varies directly with the number of doors and inversely with the number of
Talja [164]

Step-by-step explanation:

time ∝ number of door 1

time . ∝ 1/number of people. 2

compare equation 1 and 2

time . ∝ number of door / number of people

put k as constant

time = k number of door / number of people. 3

time =2. people=4 door = 10

putting in equation 3

2 = k (10)/(4)

2×4/10 = k

8/10 =k

4/5 =k

putting in equation 3

time= 4/5 number of door / number of people

now time =5 door= 25 people=?

5=4/5 (5)/ (number of people)

number of people =4/5 ×25/5

number of people= 4
