12 girls out of 30 were selected, so the ratio "selected:tried" if 12/30. This fraction can be simplified into

\dfrac{12}{30} = \dfrac{2}{5}

Similarly, 16 boys out of 40 were selected, so the ratio "selected:tried" if 16/40. This fraction can be simplified into

\dfrac{16}{40} = \dfrac{2}{5}

So yes, the ratio of the number of students on the team to the number of students trying out the same for both boys and girls

Which expression is equivalent to 2x^(2)+11x+5
beks73 [17]

Answer:

(x + 5)(2x + 1)

Step-by-step explanation:

Given

2x² + 11x + 5

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × 5 = + 10 and sum = + 11

The factors are + 10 and + 1

Use these factors to split the x- term

2x² + 10x + x + 5 ( factor the first/second and third/fourth terms )

= 2x(x + 5) + 1 (x + 5) ← factor out (x + 5 from each term

= (x + 5)(2x + 1) ← in factored form

What is the simplified form of the expression -2(-5x - 8)?
Deffense [45]

Answer: 10x+16

Step-by-step explanation:

Use the distributive property a(b+c)= ab+ac

so

-2(-5x-8) = (-2 * -5x) - (-2* -8)

=

10x-(-16)

=10x+16

Hope this helped!

What you need to know for this case is that the sum of the internal angles of a triangle is 180 °
 We then have the following equation that is given by:
 (2x) + (3x) + (4x) = 180
 Clearing x we have:
 9x = 180
 x = 180/9
 x = 20
 Therefore we have:
 m∠A = (40) °
 m∠B = (60) °
 m∠C = (80) °
 Answer:
 B) m∠B = 60 °
