X = 18
Step-by-step explanation:
Question: The sum of three numbers in order is 57. the equation that represents this is x (x 1) (x 2) = 57. which value of x from the set {16, 17, 18, 19} makes the equation true?
Answer: First you can use the equation to work out the value of x.
x + (x + 1) + (x + 2) = 57
Simplify the equation.
3x + 3 = 57.
Now solve the equation.
57 - 3 = 54
54/3 = 18
In short, The value of x is 18.
Answer:<em> 44 matches</em>
Step-by-step explanation:
<em>Let's take the given information</em>
<em>They won 37 matches</em>
<em>1/9th of their matches resulted in a draw</em>
<em>1/9 out of 90 is 9</em>
<em>You can take 90/9 and you will get 9</em>
<em>Now let us add 37+9 and you get 47</em>
<em>Now take 90-47</em>
<em>44 Matches lost</em>
<em>22/45 or 44/90</em>
27-9r
explaintion:
3•9+3•-3r
27+3•-3r=
27-9r
