Answer:
x=5
y=4
Step-by-step explanation:
The sides with the 2 bars are equal so
7x-4 = 31
Add 4 to each side
7x-4+4 = 31+4
7x = 35
Divide each side by 7
7x/7 = 35/7
x =5
The sides with 3 bars are equal
4y+8 = 24
Subtract 8 from each side
4y+8-8 = 24-8
4y = 16
Divide by 4
4y/4 = 16/4
y =4
Answer:
Yes.
Step-by-step explanation:
Yes, because we can replace x^3 by another variable, say y:
x^9 - 5x^3 + 6 = 0
Let x^3 = y, then we have x^9 = (x^3)^2 = y^2:
y^2 - 5y + 6 = 0 which is quadratic from.
So he has to sell it at 19.5+2=21.5 dollars
so assume19.5=100%
the markup is 2 dollars
2=x%
find x if 19.5=100%
so since they are proportionite
19.5:100 and 2:x
if we make them fractions and flip one of them then multiply we will get 1 since
2/4=1/2
2/4 times 2/1=4/4=1 so
19.5/100 times x/2=19.5x/200=1
19.5x/200=1
multiply both sides by 200
19.5x=200
divide both sdies by 19.5
x=10.256 aprox
x=10.3% markup
