Of means multiply

3/5 *n=30

3/5 5/3 cancels than you do 30 *5/3 =50

The answer is 50 you can check your answer by doing 3/5 *50=150/5 or 30 so it's correct .

#is5 how I got the answer well it say 10times a number so u know u gotta multiply 10by a number ,then it said increase by 9 there it then said the number was 59 so I said 10times 5 +9=59 in other words 10x +9=59
first your gonna bring over the 9 to the other side of the equation so ur gonna have 10x=59-9cause if it was positive first then the sign changed to negative when u brought it over to the other side so now u subtract 9from 59and u get 50so now u got 10x =50 so now ur gonna divide both sides by 10to get the x by itself so now on one side u got 10÷19x and the other side 50÷10 now u have x=5

One number is one more than a second number. Five times the first is 3 less than 6 times the second. Find the numbers.
TiliK225 [7]

The value of the first number is 9 , and

the value of the second number is 8 .

In the question ,

statements about two numbers is given ,

let the first number be x ,

let the second number be y .

According to the first statement " One number is one more than a second number "

translating it into the equation form , we get

x=y+1      ...(i)

According to the second statement which states " Five times the first is 3 less than 6 times the second "

translating it into the equation form , we get

5*x = 6*y - 3

5x = 6y - 3

Substituting the value of x from equation (i) , we get

5(y+1) = 6y - 3

5y + 5 = 6y - 3

6y-5y = 5+3

y = 8 ,

substituting  y=8 in the the equation (i) ,

x = 8 + 1

x = 9

hence the first number = 9  and the second number = 8 .

Therefore , the value of the first number is  9, and

the value of the second number is 8 .

C) If f(3x + 4)=5x + 8, find f '(x) and f(3)​
PIT_PIT [208]

Answer:

f(3x + 4) = 5x + 8

⇔ f(3x + 4) = \frac{5}{3}(3x+\frac{24}{5})

⇔ f(3x + 4) = \frac{5}{3}(3x+4+\frac{4}{5})

⇒ f'(x) = \frac{5}{3}(x+\frac{4}{5})

=> f(3) = \frac{5}{3}(3+\frac{4}{5})= \frac{19}{3}

Choose the correct answer
vivado [14]
This is actually called a mapping diagram but the answer is C.

Because the right circle represents the x variable and the left circle is the y variable. So you just follow the arrows. -3 is pointing to 4 so that's a pair or (-3,4)
