Answer:
Step-by-step explanation:
Well, the ratio of yellow beads to blue beads is 4:5. The best way I think is to guess and check multiplying the ratio by integers. You need between 15 and 20.
4 : 5 ( = 9 too little )
8 : 10 ( = 18 just right)
12 : 15 ( = 27 too much)
So per necklace, 8 yellow beads and 10 blue beads would be needed.
I hope this helps :-)
Answer:
-y = 3x - 4
Step-by-step explanation:
- - 3x to get - y + 2 = - 3x
- - 2 to get - y = - 3x - 2
- Replace the - 2 with 4 from the points
- Make it a negative
Answer:
2y-x= -10
3y-x = 18
Step-by-step explanation:
The correct option is . 2y-x = -10 , 3y-x = 18
one half x − 5 = 1/2 (x-5)
one third x + 6 = 1/3 *(x+6)
1/2 x-5 = 1/3x+6 =y
y= 1/2x-5
y = 1/3x+6
Now,
y=x/2 -5 equation 1
y = x/3 +6 equation 2
By taking L.C.M of the first equation we get:
y=x/2 -5
y= x-10/2
Now multiply both terms by 2.
2y=x-10
2y-x= -10
Now lets solve second equation:
Take L.C.M of the second equation:
y = x/3 +6
y=x+18/3
Multiply both sides by 3
3y= x+18
3y-x = 18
Therefore the system of equations we get is:
2y-x= -10
3y-x = 18 ....
