Answer:

$0.76$

Step-by-step explanation:

Probability = Number of favorable outcomes / Number of possible outcomes

There are $16$ favorable outcomes ( the $8+8=16$ marables that are either blue or red).

There are 21 possible outcomes ( the $8+5+8=21$ total marables).

P (draw a blue or red marable) $=\frac{16}{21}$ ≈ $0.76$

2n-7/3 = 15 solve for n

WITCHER [35]

$2n- \frac{7}{3} =15$
$2n- \frac{7}{3} =15$ common denominator is 3
$3(2n- \frac{7}{3} )=3*15$ distributhing 3 through parantheses
$3*2n- \frac{3*7}{3}=3*15$
$3*2n-7=3*15$
$6n-7=45$ add7
$6n=45+7$
$6n=52$ divide by 6
$n= \frac{52}{6}$ simplify
$n=8 \frac{2}{3}$ ⇒ $\frac{26}{3}$

The given equation has no solution when C is equal to what number?<br><br> 2x+C(8+x)=16

3241004551 [841]

Answer:

$-2$

Step-by-step explanation:

When $C=-2$ , the variable $x$ will be removed from the equation ( $2x-2x=0$ ). Therefore, we are left with $-16\neq 16$ . Thus, when $C=-2$ , the given equation has no solutions.

x-18=44

x=44-18
