Answer:
6 miles per gallon
Step-by-step explanation:
Given : An experimental vehicle was able to travel 3/8 miles on 1/16 gallon of water.
To Find: At this rate, what was the mileage in miles per gallon of water for this vehicle?
Solution:
Since An experimental vehicle was able to travel 3/8 miles on 1/16 gallon of water.
So, the mileage in miles per gallon of water for this vehicle:




Thus the mileage of water for this vehicle is 6 miles per gallon
Meter B is the answer....
Answer:
a) 3 b) y = 3x + 11
Step-by-step explanation:
a)
In order to find the gradient (slope), find the change in y or change in x (rise/run).
-2 - 2 / 7 - (-5)
-2 - 2 / 7 + 5
-4/12 = -1/3
Now that we know the gradient of line AB is -1/3, take the opposite reciprocal of that to find the gradient perpendicular to line AB.
-1/3 ⇒ 3
b)
Take point C's values and the perpendicular gradient found earlier and substitute them into the point-slope form equation.
y - 5 = 3(x - (-2))
y - 5 = 3(x + 2)
y - 5 = 3x + 6
y = 3x + 11
Ryan's marbles = x
Marie has 4 times less marbles then Ryan would have if he lost 15 marbles (it means he would have x-15)
So, Marie marbles = (x-15):4
If Ryan lost 75 marbles (it means he would have x-75), he would have 1 1/2 times as many marbles as Marie.
We got an equation:
Multiply both sides by 8:

Add 600 and subtract 3x on both sides:

Divide both sides by 5:

Answer: Ryan have 111 marbles.
