Value of the expression will be 7

<u><em>Explanation</em></u>

Given value of the variables are : p= \frac{1}{2} and q=7

Given expression: 8p+3q-18

So, <u>plugging the values</u> of p and q into the above expression, we will get...

8p+3q-18\\ \\ = 8(\frac{1}{2})+3(7)-18\\ \\ =4 + 21-18\\ \\ =25-18\\ \\ =7

So, the value of the expression will be 7.

A stadium has 50,000 seats. Seats in section A cost $30, seats in section B cost $24, and seats in section C cost $18. the numbe
svetoff [14.1K]

Answer:

Section A = 25,000 seats

Section B = 14,600 seats

Section C = 10,400 seats

Step-by-step explanation:

Total Seats = 50,000

Seats in Section A cost = $30

Seats in Section B cost = $24

Seats in Section C cost = $18

Total sales from the event = $1,287,600

No. of Seats in section A = No. seats in Section B + No. seats in Section C

A = B + C

or, 2A = 50,000

A = 25,000 seats @ $30/seat = $750,000

B + C = 25,000

24B + 18C = 537,600

24B + 18(25,000 - B) = 537,600

24B + 450,000 - 18B = 537,600

6B = 87600

B = 14,600

C = 10,400

Hence;

A = 25,000 seats

B = 14,600 seats

C = 10,400 seats

What is 1 7/8 Times 2 1\3
slamgirl [31]
We need to convert the mixed fractions into improper fractions.

1*8 = 8 
8+7 = 15

15/8 

2*3 = 6
6+1 = 7

7/3

Now we can finish and multiply

\frac{15*7}{8*3}

15*7 = 105
8*3 = 24

Simplify 105/24

105/24

24*4 = 96

105 - 96 = 9

4 is the whole number, and 9 is the numerator.

4  9/24

Simplify that,

9/3 = 3
24/3 = 8

4  3/8

Answer: 4\frac{3}{8}

Please help me it’s due tomorrow
Ierofanga [76]

Answer:

8 units

Step-by-step explanation:

so there is something called Pythagorean thereon and it states that a^2+b^2=c^2

and 6 is either a or b

and c is ten so

6^2+b^2=10^2

36+b^2=100

b^2=64

here you need to find the square root in order to delete the power so

\sqrt{b} =\sqrt{64\\\\

b=8

or

x=8
