Answer:
y = 156
Step-by-step explanation:
The equation for direct variation is
y = kx
65 = k*5
Divide each side by 5
65/5 = k
13 =k
The equation is y = 13x
Let x = 12
y = 13*12
y = 156
All numbers are whatever you want them to be except k, k is 14 so 8•14=112 112 subtract -2 equals 114 Do not find out what L is or the k at the end and now that youre reading this I wanna tell you Im in 5th grade and I have no clue what Im talking about so good luck!
20 is the answer

Answer:
1:4; C
Step-by-step explanation:
If you roll two cubes, they have 6 sides meaning 6 is the highest number. That's 2 more then 4 so I will subtract to two from each which makes it certain I will roll two dice less then 4. Removing two from each is 4 ergo the answer is 1:4
Answer:
- Small cups were 98
- Large cups were 57
Step-by-step explanation:
Ashley sold small cups of lemonade for $1.25 and;
Large cups of lemonade for $2.50
The total number of cups = 155 cups
Total sales = $265
Let number of small cups sold be (s) and a number of large cups sold be (l)
This forms a simultaneous equation below:
s + l = 155 ... (i)
1.25s + 2.5l = 265 ... (ii)
Multiplying (i) by 1.25 and (ii) by 1 we get:
1.25s + 1.25l = 193.75 ... (i)
1.25s + 2.5l = 265 ... (ii)
Subtracting (i) from (ii) we get:
0s + 1.25l = 71.25
1.25l = 71.25
l = 71.25 ÷ 1.25 = 57
So the number of large cups = 57 and;
the number of small cups = 155 - 57 = 98
