Answer:
If 2/3 of the girls in class have brown eyes and 1/4 of the girls have blue eyes, what fraction of the girls in class have neither blue nor brown
Step-by-step explanation:
2 lines parallel, and 2 triangles have a common angle
So the smaller Δ is similar to the bigger Δ (AA Similarity)
9:(4x-2)+9=12:(3x+2)+12
9:4x+7=12:3x+14
9(3x+14)=12(4x+7)
27x+126=48x+84
21x=42
x=2
So the answer is x=2
Answer:
x=8
Step-by-step explanation:
5x+10+130=180
5x+140=180
5x=40
x=8
Answer:
In year 2013 annual maintenance done = $ 3,000,000
Out of this 85% is expected to renew in 2014 = 
= $2,550,000
Now Sales in 2013 = $3,000,000
60% of these sales = 
= $1,800,000
Now out of this 60%, 20% annual maintenance was expected to be paid
In 2014 = 
= $360000
So, Total annual maintenance in 2014 = 
= $2,910,000
Answer:
The mistake there is the expression shown is not in PEMDAS.
<em>PEMDAS rule states that the order of operation starts with the parentheses first or the calculation which is enclosed in brackets. Then the operation is performed on exponents(degree or square roots) and later we do operations on multiplication & division and at last addition and subtraction.</em>
Step-by-step explanation:
1 + 4 x 9 4 x 9 = 36
1 + 36 36 + 1 = 37
37
Always remeber to use multiplication first!
