Formula: Distance = rate * time
570 = (R+(R-18))*3
570 = (2R - 18)*3
190 = 2R-16
208 = 2R
R = 104
Eastbound Train: 86mph
Westbound Train: 104mph
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:
Step-by-step explanation:
X=4
4×4=16
Considering High School level question, answer can be written as:
A system of 2 linear equations is [two] dimensional. It is a graph of [two] lines. The solutions can be [unique] solution if the graph intersects. [No] solution if the lines are parallel - meaning they have the same slope, or [Infinitely many] solutions if they are the same line.
Explanation:
when two lines are drawn on a two-dimensional plane then there are only three possible cases:
Case1: lines will intersect
In that case you will get a unique solution at the intersection point.
Case2: lines are parallel but don't touch each other
In that case there will be no point which lies on both lines so No solution.
Case3: lines are overlapping.
In that case all the points lies on both lines so infinitely many solutions.
I'm pretty sure your answer should be $4.50 for each drink. I multiplied the price of the popcorn (3.75 including the tax) by 4, since there are 4 people, which gave me 15. Then take 15 out of 33.00 which gave me 18. Divide 18 by 4 (number of people) and get 4.5 or 4 1/2 which equals out to $4.50 for each drink.
3.75 · 4= 15
33.00 - 15= 18
18 ÷ 4= 4.5 or 4 1/2
Hope this helps! =^-^=
