Alright, here's one for Algebra:
Wewaii [24]
Let x= number rows
Then x + 5 = number of seats per row

x(x+5) = 126
X^2 + 5x = 126
x^2 + 5x -126 = 0; now factor or use quadratic:
(x+14)(x-9) = 0; so the answers are either -14, or 9, and since -14 is not possible in this case because you can't have a negative number of rows, the answer is 9 rows.

Check work: number of rows = 9, number of seats per row = 9+ 5= 14, and 9 x 14 = 126

A girl found dress fo £65.50 and there was an 15% sale on
Alika [10]

Answer: $65.50 - 15% = 55.675


Step-by-step explanation:

Conversion a decimal number to a fraction: 65.50 = 655

10

= 131

2

Conversion a decimal number to a fraction: 9.825 = 9825

1000

= 393

40

Subtract: 65.5 - 9.825 = 131

2

- 393

40

= 131 · 20

2 · 20

- 393

40

= 2620

40

- 393

40

= 2620 - 393

40

= 2227

40


The common denominator you can calculate as the least common multiple of the both denominators - LCM(2, 40) = 40
