Two numbers are in ratio 5: 3,if the differ by 18 what are the numbers

45

27

Step-by-step explanation:

Let the larger number = x

Let the smaller number = y

5/3 = x/y

The numbers differ by 18

x - y = 18                      Add y to both sides

x = 18 + y                      Substitute for x in the ratio

5/3 = (18 + y)/y             Cross multiply

5y = 3(18 + y)               Remove the brackets

5y = 54 + 3y                Subtract 3y from both sides

5y - 3y = 54 + 3y-3y    Combine

2y = 54                        Divide by 2

2y/2 = 54/2    

y = 27

The smaller number is 27

x = y + 18

x = 27 + 18

x = 45

The larger number is 45

answer: can and shows the work

step-by-step explanation:

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
