Step-by-step explanation:
4x+5y=4 (equation 1)
2x-y=9 (equation2)
solving equation 1 and 2 and multiplying equation 2 by 2
4x+5y=4
4x-2y=18
- + -
________
7y= -14
y= -2
putting the value of y in equation 2
2x-y=9
2x+2=9
2x=7
x=3.5
Answer:
w=7.8

Answer:
The weight of sunflower seeds in each snack bag is 1/16 of a pound
Step-by-step explanation:
Here, we want to know the weight of sunflower seeds in each snack bag.
The total weight bought is 9/16 pound and the division is into 9 bags

9/16 divided by 9
= 9/16 * 1/9 = 1/16
There all kinds so it would keep going on with nines
Let the number be x
3x - 5 = 14
3x = 19
X = 6 1/3 or 6.333333...
