Answer:
D
Step-by-step explanation:
Because trinomial is a expression which consists of three terms
Y= (2x-20)/ 5 then you replace y so with a simple calculation u get x than u replace x with it value to get y as simple as that
Answer: [6x]
Step-by-step explanation:
(8 - 9x) = [1x]
(-10 + 7x) = [17x]
(14 - 16x) = [2x]
(12 - 24x) = [12x]
12x - 2x - 17x - 1x =
10x - 16x = [6x]
Answer:
r = 15
Step-by-step explanation:
10(8r + 23) = 1430
Divide both sides by 10.
8r + 23 = 143
Subtract 23 from both sides.
8r = 120
Divide both sides by 8.
r = 15
