Answer:
10 boys, 15 girls
Step-by-step explanation:
Original ratio: 2 boys/3 girls
let x be the scale factor of the ratio
2x plus 5 boys over 3x girls = 1 (because the # of boys/girls are the same)-------> 2x+5/3x = 1
Simplify: 2x+5=3x
Simplify: 5=x
plug x back into the original ratio: 10/15
Check: 10/15 = 2/3
10 boys + 5 boys = 15, 15/15 = 1

Answer:
C) m∠H = 85°
Step-by-step explanation:
<em>KL is the mid-segment of the triangle</em>, and is correlated with line GH, therefore, they are parallel. This means that <em>m∠K = m∠G and m∠L = m∠H</em>, because they are corresponding and on parallel lines.
By substitution, m∠H = 85°
To solve this you will be needing to use PEMDAS!
Parenthesis exponents multiply divide add subtract!
So first parenthesis...
609-78=531
So now we write the problem like this
10*80+531-10^2
Now exponents
10^2 is a exponent so that =10*10 which = 100
So we write it out again like this: 10*80+531-100
Now we need to multiply from left to write
So 10*80=800
Re-write it:
800+531-100
So now we need to add from left to write
800+531=1331
1331-100=1231
So your answer is 1231.
Does this help any?
