$15 I believe, apologies if incorrect!
By subtracting 25 from both sides, you get:
AB+CD-25=0
by subtracting CD from both sides, you get;
AB=25-CD
by subtracting AB from both sides, you get:
CD=-AB+25
Let’s start with “five more than a number x.” This translates to:
x + 5
This is “less than” 17, so we insert the corresponding symbol and add 17 to the right side of the equation:
x + 5 < 17
This is the translation of the inequality. Now we have to solve it. To do so, simply subtract 5 from both sides of he equation:
x + 5 ( – 5 ) < 17 ( – 5 )
x < 12
This is the solution to the translated inequality.
I hope this helps!
Answer:
The numbers are 5 and 20 respectively.
Step-by-step explanation:
Let two numbers are x and y.
According to question-
x + y = 25...............................(i)
Given x is smaller number and y is larger number.
then,
2 y - 3 x = 25..........................(ii)
To solve equation (i) and (ii)-
Firstly multiply by 3 in equation (i) and then add in equation (ii)-
<em> 3 x + 3 y = 75</em>
<em><u>- 3 x + 2 y = 25</u></em>
<em><u>5 y = 100</u></em>
<em>y = 20</em>
Put y = 100 in equation (i)-
We get,
<em>x = 25 - 20</em>
<em>x = 5</em>
<em>Therefore x = 5 and y = 20 .</em>
