Work out the size of angle y.

y = 38

Step-by-step explanation:

exterior angle of a triangle = sum of its interior opposite angles

129 = 91 + y

y = 129 - 91

y = 38

y = 38°

Step-by-step explanation:

y + 91° = 129° (opp. ∠s = ext. ∠)

y = 129° - 91°

y = 38°

In a triangle, the two opposite angles of an angle equals to the exterior angle that is adjacent to that angle on a straight line.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
