Answer:
30 mins
Step-by-step explanation:
<em>speed = distance/ time </em>
speed of car A
= 20/ 12 km/ min
= 5/ 3 km/ min
also, speed of car A = speed of car B
speed of car B = 5/ 3 km/ min = 50km / time taken (in mins)
=> t = 30 mins
Hey there! :)
Answer:
y = 11.
Step-by-step explanation:
Set both of the equations equal:
5x - 9 = x² - 3x + 7
Rearrange the equation:
0 = x² - 3x - 5x + 9 + 7
Combine like terms:
0 = x² - 8x + 16
Factor:
0 = (x -4)²
Solve for x:
0 = x - 4
x = 4.
Plug this into an equation to solve for 'y':
y = 5(4) - 9
y = 20 - 9
y = 11.
Answer:
it marked the bike up by 69 percent
Step-by-step explanation:
Answer:
M is not parellel to N because they do not create supplementary angles with the lines that it passes through.
J and K are parallel to each other because they create supplementary angles with line m
supplementary angles add up to 180 and if parallel lines create supplementary angles with the line they cross then they are parallel to each other if that makes sense
105+75=180
Step-by-step explanation:
Answer:angle m
