<span>3 tanks because he can do 400 miles on tank, and he's goin 1,100 miles, he does 400 miles with first tank, next tank he gets to 800 miles, and then he uses 3/4 of last tank to get to 1,100, he will then have 100 miles left on the tank though.</span>
Answer:
Step-by-step explanation:
x and y are supplementary angles, so their sum is 180°.
x+y = 180°
x is 16° less than three times y
x = 3y - 16°
(3y-16°) + y = 180°
4y = 196°
y = 49°
x = 3y-16° = 131°
Answer:The average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.
Step-by-step explanation:
Answer:
x=1 y=3
Step-by-step explanation:
3x+y=6 is the same as y=6-3x
2x-y=-1 is the same as y=2x+1
set them equal to each other
6-3x=2x+1
5x=5
x=1
substitute the value of x into either equation
y=2(1) +1
y=3
