Step-by-step explanation:

9x-7=-7

add 7 to both sides

9x=0

plug in 0 for x in the equation

9(0)-7=-7

9×0=0

A stadium has 50 comma 00050,000 seats. Seats sell for ​$3030 in Section​ A, ​$2424 in Section​ B, and ​$1818 in Section C. The
Mariulka [41]

A= B+C

As given, A+B+C = 50000 seats

A+(B+C) = 50000

2A = 50000

A= 25000 seats

Now section A sells seats at $30 each

So, 25000\times30=750000

Now, B+C = 25000

B = 25000-C

B sells at $24 and C sells at $18

So, 24B+18C = 538800

Now as section A incurs an amount of $750000 from booking, so B and C will incur 1288800-750000 = 538800 where $1288800 is the total booking amount.

24B+18C = 538800

24(25000-C)+18C=538800

600000-24C+18C=538800

6C = 61200

C = 10200

Now, B = 25000-C

B = 25000 - 10200 = 14800

Hence, section A has 25000 seats

Section B has 14800 seats

Section C has 10200 seats

What are two fractions equal to 2/5?
Georgia [21]
Two fractions that are equal to 2/5 are 4/10 and 6/15. In order to find fractions that are equal to it, just multiply both the numerator and the denominator by any number. I multiplied them by 2 and 3, to keep things simple.

2 x 2 = 4
2 x 5 = 10
4/10

2 x 3 = 6
5 x 3 = 15
6/15

Hope this helps!
