Step-by-step explanation:
x2 - x - 6 = 0
x2 - 3x + 2x - 6 = 0
x(x - 3) + 2(x - 3) = 0
x - 3 = 0. x + 2 = 0
x = 3 x = - 2
Option no 2 and 5 are the correct answer
Step-by-step explanation:
Let x be the miles Kenyon ran on tuesday
Let y be the miles Kenyon ran on thursday
Given,
Mon + Tues + Wed + Thu = 8mi
also given,
Now we have x + y = 5.2 as equation 1 and -x + y = 0.4 as equation 2
Using equation 1,
Substitute this equation into equation 2.
Substitute y = 2.8 into equation 1.
Therefore Kenyon ran 2.4 miles on tuesday, and ran 2.8 miles on thursday.
Direct variation is constantly proportional (constant multiple)
Answer:
a) y = - 1/2 x
Answer:
x = 175 units
Step-by-step explanation:
x is to (49 + 576) as 49 is to x
x/ 625 = 49/x cross multiply
x^2 = 30625
x=175
Whoever travels at the faster rate will arrive first.
We need to find and compare two unit rates:
11 miles
------------ = 0.917 miles per minute
12 min
26 miles
--------------- = 1.083 miles per min
24 minutes
It's obvious that Marisol is driving faster. She will thus be first to arrive at the concert.
