Answer:

x = 42

Step-by-step explanation:

$\frac{18}{15}$ = $\frac{x}{35}$ ⇔ $\frac{6}{5}$ = $\frac{x}{35}$ ⇔ $\frac{6*7}{5*7}$ = $\frac{x}{35}$ ⇒ x = 42

Someone help. pls and ty answer only if u know the answer pls

zmey [24]

Answer:

It is not permitted the denominator to be zero as we can't divide by zero.

Non- permissible values are:

ab² = 0
a = 0, b = 0

3n + 1 = 0
n = -1/3

4 - a = 0
a = 4

x² - x - 12 = 0
(x - 4)(x + 3) = 0
x = 4 or x = -3

10x³ - 92x² + 18x = 0
2x(5x² - 46x + 9) = 0
x(5x - 1)(x - 9) = 0
x = 0, x = 1/5, x = 9

Pls answer! I don’t know math @ all

The probability that the outcome is a sum that is a multiple of 6 or a sum that is a multiple of 4 is $\frac{5}{12}$ .

Solution:

Total number of outcomes N(S) = 36

Let A be the sum that is a multiple of 6 and

B be the sum that is a multiple of 4.

Sum that is a multiple of 6 = (1, 5), (2, 4), (3, 3), (4, 2), (5, 1), (6, 6)

N(A) = 6

Sum that is a multiple of 4 = (1, 3), (2, 2), (2, 6), (3, 1), (3, 5),

(4, 4), (5, 3), (6, 2), (6, 6)

N(B) = 9

$$P(A)=\frac{N(A)}{N(S)}$

$$P(A)=\frac{6}{36}=\frac{1}{6}$

$$P(B)=\frac{N(B)}{N(S)}$

$$P(B)=\frac{9}{36}=\frac{1}{4}$

Probability that the outcome is a sum that is a multiple of 6 or a sum that is a multiple of 4:

$P(A \cup B)=P(A)+P(B)$

$$P(A \cup B)=\frac{1}{6} +\frac{1}{4}$

$$=\frac{2+3}{12}$ (Make the denominator same)

$$=\frac{5}{12}$

Hence the probability that the outcome is a sum that is a multiple of 6 or a sum that is a multiple of 4 is $\frac{5}{12}$ .
