Answer:
15/60.
Step-by-step explanation:
25/100 is 1/4 so a 4th of 60 would be 15. 1/4 = 1/4
1)-3=z+4
z=-4-3=-7
answer is C
2)z-4=-8
z=-8+4=-4
answer is C
3)6.4=4x
4x=6.4/4
x=1.6
answer is B
4)-9=r/4
r=-9×4=-36
answer is D
5)-9=3/8n
n=-9×3/8
n=-24
answer is A, I guess, because there are two = signs, so perhaps this is a mistake and there should be - instead of =
You need to come up with an array of answers for x and y that will be greater than 0.
x+4y>0. example if x is -1 and y is 1 will this be correct.
-1+(4*1)>0, -1+4>0. 3>0? Yes
if x is 1 and y is -1 then the equation becomes 1+(-4)>0 -3 is not>0 so it's not in the array
x could be -3 and y 1
You will plot a line to show all the answers.

25% of $35 is 8.75, so the price would be $26.25. plus tax, the final price would be $27.825 or $27.83. if that doesn't work, try $27.82
(i was wrong before, this should be right now)
