Answer:
the batteries and the newspaper
Step-by-step explanation:
its the batteries and the newspaper because he didn't intend to get that when he went to the store. It was an impulse. Note the impulse purchase.
Value of x=-225
Value of y=71.33
Explanation
:
2x/3-2x/5=-60 (1)
0.2x+0.9y=19.2 (2)
(2x*5-2x*3)/(3*5)=-60
(10x-6x)/15=-60
4x/15=-60
4x=15*-60
4x=-900
x=-900/4=-225
consider (2)
0.2x+0.9y=19.2
substitute the value of x in (2)
0.2*-225+0.9y=19.2
0.9y=19.2+45=64.2
y=(64.2)/(0.9)=71.33
The y-intercept (or line intercept) is 1, and the slope is 3
4*2/5 = 22/5
16*1/2 = 33/2
22/5 ............. 1 min
33/2 ..............x min
x = 33/2 : 22/5 = 33/2 x 5/22 = 165/44 = 3,75 min
