4x – 5 = 7 does not have an integer as its solution.
Solution
Transcript
False.
Consider the eqaution, 4x – 5 = 7
Transpose -5 to RHS then it becomes 5.
4x = 7 – 5
4x = 2
x = 2/4
x = ½
"hello students i am rita your mass leader tutor and today's question is three spraying machines working together can finish painting a house in 16 minutes how long will it take for five machines of the same capacity to do the same job so in this questions two things are given to us first of all number of machines number of machines and the second is time which is in minutes if there are three machines they paint a house in 60 minute and if there are five machines then how long will it take to finish the same work so in this question it is this is a case of indirect why it is a case of indirect it is a case of indirect variation indirect variation because if machines are increase then it takes less time to complete the same work and in indirect variation k is equal to x into y it means 3 into 60 is equal to 5 multiply x so 3 into 60 divided by 5 we got the value of x 5 5 and the 5 5 to the 10 it means the value of x is equal to 36 minute this is our answer i hope you like this video so please subscribe leto for more updates and do comment your questions thank you "
