It is 2.56 because per pound equals the amount
Since the sides are congruent so are the angles (SSS) so 3x+3x+3x=180 because all the angles in a triangle add up to 180 degrees
9x=180
X=20
So the answer is x =20
Answer:
4
Step-by-step explanation:
I did 60,000 divide by 30 days equal 2000
2000 divide by 500 equals 4

Answer: b = 17</h3>
====================================================
Explanation:
The line must go through the point (5,2) which means x = 5 and y = 2 pair up together.
We'll plug these x and y values into the equation and solve for b.
y = -3x+b
2 = -3(5)+b
2 = -15+b
2+15 = b
17 = b
b = 17
The equation y = -3x+b turns into y = -3x+17
this the answer of . Factorise : 625y ^ 2 + 400y - 36 + 20z - z ^ 2
