Answer:

x = 11

Step-by-step explanation:

Lines are parallel. 5x + 10 and 10x + 5 are supplements of each other.

Move 5x+ 10 to the corresponding position on the figure. It will be next to 10x + 5 and form a linear pair with 10x + 5. A linear pair form a straight angle or two supplementary angles. Supplementary angles = 180°

Therefore 5x +10 + 10x + 5 = 180°

15x + 15 = 180°

15x = 180 - 15

15x = 165

x = 11

kkurt [141]

Answer:

a) 1/24 do total

Step-by-step explanation:

We have that:

The total is 1.

The first friend gets 1/4 of the total.

The second friend gets 1/3 of the total

The third friend gets 3/8 of the total.

The remaining is x.

$\frac{1}{4} + \frac{1}{3} + \frac{3}{8} + x = 1$

The least common multiple between 4, 3 and 8 is 24. So

$\frac{6 + 8 + 3*3 + 24x}{24} = 1$

$23 + 24x = 24$

$24x = 1$

$x = \frac{1}{24}$

So the correct answer is:

a) 1/24 do total
