Answer:
x=10, y=5
Step-by-step explanation:
For substitution, you always want to get the variable alone. The second equation (x-2y=0) will be easier to substitute into the first equation.
x-2y=0
x=2y
You can substitute 2y as x on the first equation (x+4y=30).
2y+4y=30
6y=30
y=5
Plug y=5 into any equation.
x+4(5)=30
x+20=30
x=10
Since Sydney has planted 5/9 of her flowers and there were 63 flowers that are left unplanted, the first thing we are going to determine is the number of flowers that were planted. To do this, we just have to do the cross multiplication process.
So 5/9 x ?/63 = 35. Therefore, the number of plants planted were 35. To start, Sydney has a total of 100 flowers to be planted. That would be 35 + 65 is 100.
Count by 1s or 5s. Write the first five numbers you would count, starting at 15.Starting by 1s
1. 16
2. 17
3. 18
4. 19
5. 20
Next is by 5s
1. 20
2. 25
3. 30
4. 35
5. 40
20 - 13.76 = 6.24
The change after spending $13.76 would be $6.24.
