Stadium has 48,000 seats seats sell for $30 in section 8 $24 in section B and $18 in section C the number of seats in section a

Naddika [18.5K]

Answer:there are 24,000 sears in section A, 14,600 in section B and 19,400 in section C.

Step-by-step explanation:

Step 1

let the number of seats in section B = x

and the number of seats in section C.=y

Given that the number of seats in section A is the sum of seats in sections B and C, we can then say A =x + y

From the given question, We have that

seatsA + seatsB + seatsC = 48,000 which also equals

(x+y) + x + y = 48,000

2x + 2y = $48,000

2(x+y) = 48,000

x + y = 48,000/2 =24,000 which also equals

B+C =24,000

Now the number of seats in section A =24,000 and the sum of seats in sections B and C is 24000.

We now have

B+C = 24,000------ eqn (1)

Also

since we already have the number of seats for Section A, We will find Section B and C

A +B+C =1,239,600,

$30 x 24,000 + 24B + 18C= 1,239,600

720,000 + 24B + 18C= 1,239,600

24B + 18C= 1,239,600-720,000

24B + 18C= 519,600--------- eqn 2

Step 2 We will now solve with the following equations

B+C = 24,000------ eqn (1)

24B + 18C= 519,600--------- eqn 2

Multiply eq(1) by 24 (both sides). Then subtract eq(2) from it:

24B + 24C = 576,000-------eqn (3)

24B+ 18C = 519,600-- ---eqn(4)

6C = 576,000- 519,600

6C=56,400

C= 9,400

TO get B.

B+C = 24,000

B= 24,000 - 9,400

B=14,600

Therefore, there are 24,000 sears in section A, 14,600 in section B and 19,400 in section C.

26-38+(-3) what is the answer.

Norma-Jean [14]

So basically, first just do this step by step, or subtract 38 from 26 first.

26 - 38 is basically -(38 - 26), or -12.

So then, it becomes -12 + (-3)

A - and a + becomes - because you're adding negative 3.

-12 - 3

Which then becomes -15.

A bag contains 6 gray tiles and 3 blue tiles. Jenny reached into the bag and picked a tile

Arisa [49]

Answer:

The probability that Jenny picked a gray tile with her second pick given that she picked a blue tile with her first pick = 0.25

Step-by-step explanation:

i.) there are 6 gray tiles and 3 blue tiles

ii) the probability that Jenny picked a blue tile first is given by

$\frac{number\hspace{0.1cm} of \hspace{0.1cm} blue\hspace{0.1cm} tiles }{total \hspace{0.1cm}number\hspace{0.1cm} of \hspace{0.1cm}tiles\hspace{0.1cm} } = \frac{3}{9} = \frac{1}{3}$

iii) the probability that Jenny picked a gray tile with her second pick without replacing the first tile $\frac{number\hspace{0.1cm} of \hspace{0.1cm} blue\hspace{0.1cm} tiles }{total \hspace{0.1cm}number\hspace{0.1cm} of \hspace{0.1cm}tiles\hspace{0.1cm} } \times \frac{number\hspace{0.1cm} of \hspace{0.1cm} gray\hspace{0.1cm} tiles }{total \hspace{0.1cm}number\hspace{0.1cm } of \hspace{0.1cm}tiles\hspace{0.1cm} - 1 } = \frac{3}{9} \times \frac{6}{8} = \frac{1}{3} \times \frac{3}{4} = \frac{1}{4} = 0.25$

The probability that Jenny picked a gray tile with her second pick given that she picked a blue tile with her first pick = 0.25

Pls help! i don't understand this! it would rlly help if someone were to explain

shusha [124]

Answer:

C 1

Step-by-step explanation:

x-1/x-2 - x^2+4x-4/(x-2)(x+6)

rewrite: (x-1)(x+6)-(x^2 + 4x - 4)/(x-2)(x+6)

expand x^2+6x-x-6-x^2-4x+4/(x-2)(x+6)

collect like terms (x^2-x^2)+(6x-x-4x)+(-6+4)/(x-2)(x+6)

simplify x-2/(x-2)(x+6)

cancel x-2 and get 1/x+6

but that is the only answer I can get from this, so I believe many one, just because of the numerator
