Answer:

x = -13/5

Step-by-step explanation:

8+3(2x-7) = 11x

8 + 6x - 21 = 11x

Answer:

$12 is the sale price of shirt.

Explanation:

Calculate the percentage of sale

[tex]\sf \rightarrow \sf \dfrac{15}{20} *100[/tex]

[tex]\sf \rightarrow \sf 75 \%[/tex]

Then find the sale price of shirt

original price * percentage of sale

$16 * 75%

$12

Answer:

$12

Step-by-step explanation:

First, calculate the sale discount as a percentage using the given information about the pants.

[tex]\sf percent\:change=\dfrac{|final\:value-initial\:value|}{initial\:value} \times 100[/tex]

[tex]\implies \sf percent\:change=\dfrac{|15-20|}{20} \times 100=25\%[/tex]

Therefore, the clothes are on sale with a 25% discount.

This means they are 75% of the original sale price, as 100% - 25% = 75%

To find the sale price of the shirt, we simply need to find 75% of the original selling price of the shirt:

  75% of $16

= 0.75 × $16

= $12

Using ratios of original price : sale price, where x is the sale price of the shirt:

pants → 20 : 15

shirt → 16 : x

Therefore, as the ratios are the same:

   20 : 15 = 16 : x

⇒ 20/15 = 16/x

⇒ 20x = 16 · 15

⇒ 20x = 240

⇒ x = 240 ÷ 20

⇒ x = 12

Answer:

Below in bold.

Step-by-step explanation:

The 3 angles of a triangle sum to 180 degrees, so:

if one angle is x degrres the other id 2x, and:

x + 2x + 60 = 180

3x = 180 - 60 = 120

x = 120/3 = 40

So m<B = 40 and m < A = 80 degrees.

Answer: should be 74?

15 males and 20 females would maximize the total number of animals

The table is given as:

                           Males      Females    Time available

Environment a    20 min      25 min       800 min

Environment b    20 min      15 min       600 min

Represent the male with x and the female with y.

The time available is limited i.e. ≤

So, the constraints are:

20x + 25y ≤ 800

20x + 15y ≤ 600

Solve the above system of inequalities graphically (see attachment)

(x, y) = (15,20)

Hence, 15 males and 20 females would maximize the total number of animals

The probability value represented by P(A) is 0.325

The given parameters are:

P(B) = 0.4

P(A and B) = 0.13

Given that the events A and B are independent, we have:

P(A and B) = P(A) * P(B)

So, we have:

0.13 = P(A) * 0.4

Divide both sides by 0.4

P(A) = 0.325

Hence, the probability value of P(A) is 0.325
