Answer:

  • AB = 9x - 2
  • BC = 6x + 13

Since both have equal length

9x - 2 = 6x + 13

9x - 6x = 13 + 2

3x = 15

x = 15/3

x = 5

Length of BC = 6(5) + 13 = 43 cm

Step-by-step explanation:

Solution,

AB=9x-2

BC=6x+13

Now,

AC=AB+BC

=9x-2+6x+13

=15x+11

10. The sum of two numbers is 6 less than twice the first number. Their difference is 10 less than four times the second number.
Ilya [14]

Answer:

10 and 4.

Step-by-step explanation:

Let x be the first number.

Let y be the second number.

x + y = 2x - 6

x - y = 4y - 10

x = 4y - 10 + y

x = 5y - 10

(5y - 10) + y = 2(5y - 10) - 6

6y - 10 = 10y - 20 - 6

6y - 10 = 10y - 26

6y - 10y = -26 + 10

-4y = -16

y = 4

x - (4) = 4(4) - 10

x - 4 = 16 - 10

x - 4 = 6

x = 6 + 4

x = 10
