A:b = 4:5
b:c=3:2
b was 5 then it was 3, so you have to find the common multiple which is 15.
you’d have to times the 4 (a) by 3 since that 5x3 is 15
you’d have to times the 2 (c) by 5 since 5x3 is 15 again.
therefore the answer would be
a:b:c
12:15:10
I hope this makes sense it was kinda hard to explain sorry :)
Answer:
The image that is correct is the one with yellow starting at positive 4 and green at negative 4. The solution is anything less than positive 4.
Factor out the common term 4
-4(2x - y) = 24
Divide both sides by -4
2x-y= - 24/4
Simplify24/4 to 6
2x -y = -6
Subtract 2x from both sides
-y = -6 - 2x
Multiply both sides by -1
y = 6 + 2x
Answer:
You can buy 7 waffle cones.
Step-by-step explanation:
Let sundae = x
Let waffle cones = y
4.25x + 3.75y ≤ 50
4.25 (5) + 3.75y ≤ 50
21.25 + 3.75y ≤ 50
3.75y ≤ 28.75
y ≤ 7.666666666
* round to the nearest whole to get 7
