20 dived by 60 equals 0.3
2nd one, y=2x+3
so subsitute y with 2x+3 in other equation
2x-(2x+3)=7
2x-2x-3=7
0-3=7
-3=7
false
no solution
(also, the slopes of the lines are the same and therefor they are paralell and differnet y intercepts so never intersect)
no solution
12 - 3 = 9
So there are 9/12 cookies left.
So then John ate 3/12 cookies.
3/12 = 1/4
Convert into a decimal. .
1/4 = 0.25
0.25 = 25%
So, James bought 12 cookies and ate 3 of them. He ate 25% of the cookies.
There is 6 regular packs and 6 value packs so add those (6+6=12). Divide 12 by 2 (because there's 2 socks in a pair) and get 6. Then divide 402 by 6 and get 67 pairs. Do the same for the second location.
Answer:
H in terms of c is H = 5c³.
Step-by-step explanation:
Given that:
H = 40 and c = 2
H varies directly to the cube of c.
Which means that,
H ∝ c³
Let,
k be the proportionality constant.
H = kc³
Putting H=40 and c=2
Dividing both sides by 8,
Now,
H in terms of c.
H = 5c³
Hence,
H in terms of c is H = 5c³.
