Answer:
16x- 20y=20
Step-by-step explanation:
20y-20y =0
so answer is 16x
The pair of numbers that would have 20 as their lcm is 4 and 5
X²-3x-10=0
x²-(5-2)x-10=0
x²-5x+2x-10=0
x(x-5)+2(x-5)
(x-5)(x+2)
Answer:
Approximately 7.9 feet.
Step-by-step explanation:
cos 10 = x / 8 where x is the required distance.
x = 8 cos 10
= 7.878 feet.
Answer:
x = 3
Step-by-step explanation:
Since ΔABC is isosceles with ∠A = 100° then the base angles are equal, that is
∠C = ∠B , that is
14x - 2 = 12x + 4 ( subtract 12x from both sides )
2x - 2 = 4 ( add 2 to both sides )
2x = 6 ( divide both sides by 2 )
x = 3
