16<2(3x-1)<28 divide all terms by 2
8<3x-1<14 add 1 to all terms
9<3x<15 divide all terms by 3
3<x<5
x=(3,5) in interval notation
On a number line, it would be a line segment from 3 to 5 with open circles at 3 and 5.
On a coordinate system graph, it would be an infinitely high shaded plane between the vertical lines x=3 and x=5
Answer: 
r=26
Step-by-step explanation:
Given: Mrs. Morton rewards her students on behave well by putting 3 marbles into a marble jar.
If the jar contains 24 marbles. and r represent the number of additional times the class is rewarded then the required equation will be
If we solve it, we will get the minimum the jar contains 24 marbles.
To solve equation, subtract 24 from both sides, we get
Hence, the minimum whole number of additional times they need to be rewarded so they can have a party=26

Answer: $252.68
Step-by-step explanation:
Find 12.75% of 249 by using formula T= A + (A•I/100)
T=249+(249•12.75)/100)= 31.75 (taxes)
Then add taxes to room cost;
249+31.75= 280.75
Then you’d apply the coupon of 10% by using; Discount = Original Price x Discount %/100
Discount = 10% or 10/100=0.1
Discount = 280.75 x 0.1
= $28.08
Now you’d find the final price by;
Final Price = Original Price - Discount
Final Price = 280.75 - 28.075
Final Price = $252.68
Answer: 2
Step-by-step explanation:
3•(-1)^3 - (-1)^3 + 5•(-1)^3 - 9•(-1)^3
3•(-1) - (-1) + 5•(-1) - 9•(-1)
-3 +1 -5 +9= 2
