One number is nine less than another. Their sum is twenty-seven. Find the numbers.

18 is the answer

9 and 18

Step-by-step explanation:

Let the unknown number be x

According to the question

(x-9) + x = 27

Solution:

(x-9) + x = 27

x-9+x = 27

x+x = 27+9

2x = 36

x = 36/2

x = 18

Now, let's find the another number by applying the value of x

(18-9) + 18 = 27

9 + 18 = 27

27 = 27

[Therefore, the first number is 9 and the second number is 18.]

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
