x=3 and y=2 because 6+6 = 12 and 2 times 3 is 6 :)
<h2>
The required value of x is equal to 2.</h2>
Step-by-step explanation:
We have,
To find, the value of x in the given equation = ?
∴
By crossmultiplication, we get
3(3x) = x + 16
⇒ 9x = x + 16
⇒ 9x - x = 16
⇒ 8x = 16
⇒ x = 
⇒ x = 2
∴ The value of x = 2
Thus, the required value of x is equal to 2.
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
Simplify the exponents
3-2=1 therefore it should be 1/7 the third answer. Hope that helps
