7 devide by k in algebric function = 7/k
The statement
no solutions represents the simplified form of the given equation 6x + 14 = 3(2x + 5). Hence Option A is correct
<u>Solution:</u>
Given, equation is 6x + 14 = 3(2x + 5).
We have to find the correct options that represents the simplified form of the given equation and correctly describes the solution.
So, now let us simplify the given equation
⇒6x + 14 = 3(2x + 5) ⇒ 6x + 14 = 6x + 15 ⇒ 6x – 6x + 14 = 15 ⇒ 14 ≠ 15
As L.H.S not equals with R.H.S, no value of x can satisfy the equation and there will be no solution for given equation.
Hence, option A is correct.
The price of gasoline in this week is 1.05g. Option C
Step-by-step explanation:
Given,
The price of a gallon of gasoline = g in last week.
The price of gasoline increased by 5% this week.
To find the price of gasoline this week.
Formula
If an original price of an object a increased by b% the final price will be = a×
So,
The price of gasoline in this week = g×1.05 = 1.05g
[ Please note: Here option C and E have same value. So, both are correct].
Decibel is directly proportional to number of cars passing the point. That is,
69 db ----- 139 cars
x db ----- 17 cars
x = number of cars passing the point per minute on a weekend.
Then,
x= (69*17)/139 = 8.43 db ≈ 8 db
