Answer:
$57.75
Step-by-step explanation:
If 11 books cost $42.35,
11b=42.35
b=42.35/11
b=3.85
15 books will cost 15b.
15b
= 15*3.85
= 57.75.
15 Books will cost $57.75.
Answer:
77) YES , 78) YES , 79) NO , 80) YES
Step-by-step explanation:
77) 12/4=3 and 18/6=3 so YES
78) 30/6=5 and 40/8=5 so YES
79) 36/25=1.44 and 48/40=1.2 so NO
80) 15/5=3 and 13.8/4.6=3 so YES
You have to do 18/108 then move the decimal point over two places and then the answer would be 16%.
Answer:
60
Step-by-step explanation:
Answer:
5) y=-3x+1 6) y=1/2x-1
Step-by-step explanation:
5) y-y1=m(x-x1)
y-(-5)=-3(x-2)
y+5=-3(x-2)
y=-3x+6-5
y=-3x+1
------------------
6) y-y1=m(x-x1)
y-1=1/2(x-4)
y=1/2x-4/2+1
y=1/2x-2+1
y=1/2x-1
