Answer:
x=3 y=1
Step-by-step explanation:
x+y=4
y=-x+4
plug in the y
2x-(-x+4)=5
2x+x-4=5
3x=9
x=3
plug in x=3 into first equation to find y
y=-(3)+4
y=-3+4
y=1
Answer:
The black tulle is the better buy
Step-by-step explanation:
You will need to find the unit rate for the tulle...in other words cost per 1 yard to see which is the better buy.
You also need to make sure they are in the same units. So, we will convert the 3 yards to feet....which will be 9 feet
5.63/9 = 0.62555 per foot
3.58/6 = 0.59666 per foot

5% of sold is tax
22.00=tax
therefor
22.00=5% of total
5%=5/100=1/20

22.00=1/20 times totl
multiply both sides by 20/1 to clear fraction
440.00=total
cost of items is $440.00
