Answer:
Each steamer costs $2.5 and each party hat costs $1.5
Step-by-step explanation:
Let the cost of 1 steamer =x
Let the cost of 1 party hat =y
Three rolls of streamers and 15 party hats cost $30
Two rolls of streamers and four party hats for $11.
We solve the two equations simultaneously.
Multiply equation 1 by 2 and equation 2 by 3
6x+30y=60
6x+12y=33
Suntract
18y=27
y=1.5
From 6x+30y=60
6x+30(1.5)=60
6x+45=60
6x=60-45=15
x=2.5
Since x=2.5 and y=1.5
Each steamer costs $2.5 and each party hat costs $1.5
We have the expression:( x - 2 ) / ( x + 9 ) ( x - 5 )We have to find how many values of x must be excluded. The rule is : denominator must never equal zero. Anything divided by zero is undefined.x + 9 ≠ 0, x ≠ - 9x - 5 ≠ 0, x ≠ 5.Answer: Two values must be excluded, x = - 9 and x = 5.
8 1/4 pounds converted to ounces is 132 ounces. 1 pound is 16 ounces, so all you have to do is multiply the number of pounds by 16.
