Answer:
x=3cm
Step-by-step explanation:
This is a basic proportion question.
2/18 = x/27
Answer: There were 78 red apples at the party.
Step-by-step explanation:
This situation can be represented by the equation
x + 3x + 2(3x) = 130 where x is the number of green apples, 3x is the number of yellow apples and 2(3x) is the number of red apples.
Now solve for x
x +3x +2(3x) =130
4x + 6x = 130
10x = 130
x = 13
Now we know that x is 13 so put it into the expression for red apples and solve for the actual number of red apples.
2 * (3*13) = ?
2 * 39 = 78
<u><em>Answer:</em></u>
<u><em>x < -7</em></u>
<u><em>Step-by-step explanation:</em></u>
<em><u>Divide both sides by 3</u></em>
