38b + 61t = 791.50....multiply by 27
54b + 50t = 923.....multiply by -19
-------------------
1026b + 1647t = 21370.5 (result of multiplying by 27)
-1026b - 950t = - 17537 (result of multiplying by -19)
------------------add
697t = 3833.50
t = 3833.50 / 697
t = 5.50 <=== cost of each towel
38b + 61t = 791.50
38b + 61(5.50) = 791.50
38b + 335.50 = 791.50
38b = 791.50 - 335.50
38b = 456
b = 456/38
b = 12 <== cost of each bed sheet
so the cost of 1 towel and 1 bed sheet is : 12 + 5.50 = 17.50
Answer:
hello
3 x + 50 = 6 x - 10
3 x - 6 x = - 10 - 50
- 3 x = - 60
x = 20
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
When there as a remainder, polynomial division does not result in a polynomial. The set of polynomials is not closed for <em>division</em>.
1/5(t+2)=5/8
First you do 1/5 times t+2
1/5t+2/5=5/8
Then you subtract 2/5 from both sides
1/5t+2/5 - 2/5 = 5/8 -2/5
Simplify that and you get
1/5t = 9/40
Divide both sides by 1/5 (multiply by the reciprocal)
And you get 9/8 or 1 1/8
I hope this helped!
