Answer : The correct option is (A) 68.
Step-by-step explanation :
As we are given that:
LN = 6x - 5
LM = x + 7
MN = 3x + 20
Now we have to determine the value of MN.
According to the question:
LN = LM + MN
Now putting all the given values in this expression, we get:
6x - 5 = (x + 7) + (3x + 20)
6x - 5 = 4x + 27
6x - 4x = 27 + 5
2x = 32
x = 16
The value of MN = 3x + 20 = 3(16) + 20 = 48 + 20 = 68
Therefore, the value of MN is 68.
Answer:
if you make the 3.5 equal 7/2
and the 1.40 equal 7/5 its will be more easier
so7/5 × 7/2 its 4.9
sorry guys its not 4.9 i made mistake with 3.25 i was thinking that it was 3.50 any wwy
i have good method too
we can make 3.25 equal 13/4 and 1.40 equal 7/5 the multiply it
we will find 91/20 but we have problem its The 10 dont worry we can take the 10 from the both number and we will get 9.1/2 and We can devide easily now and the answer is 4.55
sorry iam trying so hard to speak engilish well sorry if u cannot understand me big respet for all the students
Let write these numbers into fractions. miles/time
You: 2/1
Your friend: 3/24= 1/8
You are running faster because you are 16 times faster
