Answer: Last equation (D)
Step-by-step explanation:
Since they want the perpendicular slope, we must take the negative reciprocal if the slope in the equation given. So the negative reciprocal of -1/3 is 3 so that takes out the first and third equation. Now we have to use point slope which is y - y1= m (x - x1) . Doing this gives us y - 5 = 3(x+2) which is the last equation.
Answer:
196 inches.
Step-by-step explanation:
We have been given that an ant can travel at a constant speed of 980 inches in every 5 minutes.
To find the distance traveled by ant in one minute we will divide total distance traveled by time taken to travel that distance.
Therefore, ant travels 196 inches in one minute.
Number of boys=x
number of girls=y.
We can suggest this system of equations:
x/y=8/7 ⇒x=8y/7
x+y=195
this system of equations can be solve by substitution method.
(8y/7)+y=195
least common multiple=7
8y+7y=1365
15y=1365
y=1365/15
y=91
x=8y/7
x=8*91 / 7
x=728/7
x=104
Answer: there were 104 boy campers and 91 girl campers.
4/5 of his total trip is 480...
4/5x = 480
x = 480 / (4/5)
x = 480 * 5/4
x = 2400/4
x = 600 <=== total distance is 600 miles
