Identify a pattern and find the next three numbers in the pattern below.
5, 10, 15, 20....
What is add 5: 25, 30, 35
Evaluate 3t(t+2)-3t2 for t=19
What is 114?
Solve (m-2) - 5 = 6
What is 13?
Solve 57-4t > 13
What is t<11.
Solve
abs(3x)=18
What is x= 6 and -6?
Name the subsets to which the number below belongs.
2 7/8
What is Real & Rational?
Simplify -(3a-2b)-3(-a-b)
What is 5b?
Solve 7y + 4=3-2y
What is -1/9?
Solve 2(m-3)+7<21.
What is m<10?
Solve
abs(3x+4)=-3
What is no solution?
Name the subsets of numbers the value below belongs to.
-.35
What is Real and Rational?
Evaluate 3(x-4) + 2x-x2 for x=6
What is -18?
Solve 2(x+4)=8
What is 0?
Solve 7x> -35 and 5x<or equal to30.
What is -5<x<or equal to 6?
Solve
abs(3x+5) -2=5xWhat is 3/2?
Name the property shown below.
(3+6)+5=(6+3)+5
What is Commutative for Addition?
Simplify 5(a-2b)-3(a-2b)
What is 2a-4b?
Is the equation always, sometimes or never true and why?
6x-12+2x=3+8x-15
What is Always True because you have the same equation on both sides and 0=0.
Solve 4x<16 or 12x>144.
What is x<4 or x>12?
abs (3x-6) +3 < 15
What is -2<x<6?
Name the property shown below.
5(1)=5
What is Identity for Multiplication?
Write the algebraic expression for
ten less than twice the sum of s and t
What is 2(s+t)-10?
Solve the equation for x.
x/a -5=b
What is x= a(b+5) or x=ab+5a where a is not equal to zero.
The following always, sometimes or never true and why.
-7(3x-7)+21x>or equal to 50?
What is never true because 49 is never greater than or equal to 50.
Write an absolute value inequality to describe the situation below.
Suppose you used an oven thermometer while baking and discovered that the oven varied between -5 and 5 degrees from the setting. If your oven is 350 degrees, let t be the actual temperature.
What is abs(t-350)<or equal to 5.
