Answer:
21
Step-by-step explanation:
you do what is parenthesis first so you would do 3 times 2 which is 6 then do 3 times 5 which is 15 well 15 plus 6 equals 21
Y = 2/1x + 6
I did the work in this photo:
Draw a diagram to illustrate the problem as shown below.
Let v = speed of the westbound car, mph
Because the eastbound car travels 4 mph faster than the westbound car, its speed is (v+4) mph.
After 2 hours,
the westbound car travels 2v miles west, and the eastbound car travels 2(v+4) miles east.
Because they become separated by 208 miles, therefore
2v + 2(v+4) = 208
4v + 8 = 208
4v = 200
v = 50 mph
The westbound car travels at 50 mph.
The eastbound car travels at v+4 = 54 mph
Answer: The eastbound car travels at 54 mph.
Answer:
B. y = -5/2x +3/2
Step-by-step explanation:
5x + 2y = 3
We want to get this in the form
y = mx +b where m is the slope and b is the y intercept
Subtract 5x from each side
5x -5x+ 2y =-5x+ 3
2y = -5x+3
Divide by 2
2y/2 = -5x/2 +3/2
y = -5/2 x +3/2
