Divide 15 in the ratio 3:2

1 answer:

7 0

One way of approaching this would be to add up 3 and 2, obtaining 5, and then multiplying 15 by 3/5:

15(3/5) = 9

Then write and solve the equation of ratios:

3 9
-- = ------
2 x

Then 3x=18, and x=6. Thus, 15 divides into 9 and 6, which has the ratio 3:2.

Solve the equation. 2(3x – 5) = 8

stiks02 [169]

You would distibute first distribute

6x-10=8

add 10 on both sides

6x=18

Then you divide 6 on both sides to get x by itself so

x=3

Winnie wrote the following riddle.I am a number between 60 and 100.My ones digit is two less than my tens digit.I am a prime num

Kazeer [188]

Answer:

Step-by-step explanation:

60<xy<100

y -2 =x

if it is prime

y cannot be even

so y could be 1,3,5,7,9

x would then be 9,1,3,5,7

but to be between 60 and 100

x must be 7 or 9

so the number must be 79 or 57

57 is not prime so

the number is 79

5 0
