Answer:
0.556
Step-by-step explanation:
such easy math
We have that
<span>10x - 4 = 2 ( ? )
</span>I proceed to replace the missing value with the given expression
case a-------------> <span>5x - 4
</span><span>then
</span>10x - 4 = 2 (5x-4 )--------> 10x - 4 = 10x-8--------> is not solution
case b-------------> 5x - 2
then
10x - 4 = 2 (5x-2 )--------> 10x - 4 = 10x-4--------> is solution
case c-------------> <span>10x - 4
</span>then
10x - 4 = 2 (10x - 4 )--------> 10x - 4 = 20x-8--------> is not solution
case d-------------> <span>10x - 8
</span>then
10x - 4 = 2 (10x - 8 )--------> 10x - 4 = 20x-16--------> is not solution
the answer is the option b) 5x - 2
It will take her 12 minutes to run a full mile
first you convert to slope intercept form
3x+y = 5 is the same as y = -3x+5
x - 4y = 32 is the same as y = 4x-8
then you graph
(starting with the y-intercepts as your first points)
the point where the two lines intercept is your solution.
