Answer:
-2
Step-by-step explanation:
x + 3 = 2x + 5
-2 = x
Answer:
Step-by-step explanation:
(x-2)/2 = -3
x - 2 = -6
x = -4
(y + 2)/2 =4
y + 2 =8
y = 6
(-4, 6)
Answer:
60 chickens
Step-by-step explanation:
We assume the 140 refers to the number animals (heads, noses, bodies, whatever). If all of those were chickens, there would be 280 legs. There are 160 legs more than that.
Since each pig that replaces a chicken adds 2 legs, there must be 160/2 = 80 pigs. That leaves 140 -80 = 60 chickens.
Answer:
Slope = 1/9
Step-by-step explanation:
Use the formula for the slope of a line given two points. I've attached a photo to remind you what the formula is.
m is the slope of the line.
(x1, y1) = (-4, 4) and (x2, y2) = (5, 5)
So plug in the numbers into the formula, which yields:
m = 
m = 
80% decrease. because 1% of 300 is 3 which you multiply 3*20 and which means 20 percent equals $60 the leftover percent is the decrease
