Answer:
4
Step-by-step explanation:
The ratio of green : pink = 32 : 56 = 4 : 7
After 7 pink are given away, then
ratio = ? : 49 = 4 : 7 ← ratio has to be the same
Using proportion
=
( cross- multiply )
7? = 196 ( divide both sides by 7 )
? = 28
Thus the ratio = 28 : 49 = 4 : 7
Thus 32 - 28 = 4 green should be given
Use any letter "x" is the usual one but since you have 2 you can use 2 different ones.
95,500
95,498 498 is closer too 500 than 490 if its 5 or move go up a level if its 5 or less go down a level
Answer:
No
Step-by-step explanation:
Say the price of 1 apple is x and the price of 1 orange is y. Then, we can write the two equations:
4x + 4y = 10
6x + 6y = 15
We can try to solve this by elimination, which means getting rid of one variable so that we're left with only 1 variable to solve for. Multiply the top equation by 3 and the bottom equation by 2:
3 * (4x + 4y) = 10 * 3 ⇒ 12x + 12y = 30
2 * (6x + 6y) = 15 * 2 ⇒ 12x + 12y = 30
Subtract the bottom equation from the top:
12x + 12y = 30
- 12x + 12y = 30
______________
0 + 0 = 0
Since we result in 0 = 0, that means any values of x and y we put into the equations will work, so we cannot find a unique price.
Hope this helps!
