Answer:
50 mph, 62 mph
Step-by-step explanation:
Their total speed is found from ...
speed = distance/time
speed = (364 mi)/(3.25 h) = 112 mi/h
If s is the speed of the slower car, then ...
s + (s+12) = 112 . . . . . their total speed is 112 mph
2s = 100 . . . . . . . . . . simplify, subtract 12
s = 50 . . . . . . . the speed of the slower car
s+12 = 62 . . . . the speed of the faster car
1/2 for the dime and 0 for the die
The answer to that question is K or the constant of proportionality is 2/3.

Answer:
13 =x
z =88
Step-by-step explanation:
7x+1 is a vertical angle to 9x -25
That means they are equal
7x+1 = 9x-25
Subtract 7x from each side
7x-7x+1 = 9x-7x-25
1 = 2x-25
Add 25 to each side
1+25 =2x-25+25
26 = 2x
Divide by 2
26/2 = 2x/2
13 =x
7x+1 and z are supplementary angles, which means they add to 180
7x+1 +z = 180
We know x
7(13) +1 +z = 180
91 +1 +z = 180
92 +z = 180
Subtract 92 from each side
92-92 +z = 180-92
z =88
