Answer:
$-5.04 a
Step-by-step explanation:
I believe that a box of 50 for $23.59 would be a better deal because 23.50 divided by 50 would equal 0.47, or in this case, 47 cents. 44.95 divided by 100 equals 0.4495, or 4495 cents. I think I'm wrong, but you can take this answer if you'd like
Answer:
2/19
Step-by-step explanation:
x+2 (9x) = 2
x+18x=2
19x=2
19x/19=2/19
2/19
Answer:
7/11
Step-by-step explanation:
Answer:
p= 2.5
q= 7
Step-by-step explanation:
The lines should overlap to have infinite solutions, slopes should be same and y-intercepts should be same.
Equations in slope- intercept form:
6x-(2p-3)y-2q-3=0 ⇒ (2p-3)y= 6x -2q-3 ⇒ y= 6/(2p-3)x -(2q+3)/(2p-3)
12x-( 2p-1)y-5q+1=0 ⇒ (2p-1)y= 12x - 5q+1 ⇒ y=12/(2p-1)x - (5q-1)/(2p-1)
Slopes equal:
6/(2p-3)= 12/(2p-1)
6(2p-1)= 12(2p-3)
12p- 6= 24p - 36
12p= 30
p= 30/12
p= 2.5
y-intercepts equal:
(2q+3)/(2p-3)= (5q-1)/(2p-1)
(2q+3)/(2*2.5-3)= (5q-1)/(2*2.5-1)
(2q+3)/2= (5q-1)/4
4(2q+3)= 2(5q-1)
8q+12= 10q- 2
2q= 14
q= 7
