This is a test
constraint, inequality, equation, expression, angle
angle
x+3=9
x=
x=6
4x=20
x=5
How do 4, 3, -5, and 10 degrees all compare to -23 degrees.
(use greater than, equal to, less than)
They are GREATER THAN -23.
Current President?
Joe Biden
A mathematical sentence that shows that two expressions are equivalent (has an equal sign)
(Example: 2x=6
constraint, inequality, equation, expression, angle
equation
6 + x =14
x=
x=8
x/6=9
x=54
Write x is greater than 25 degrees as an inequality
x > 25
First President?
George Washington
A mathematical phrase that contains operations, numbers, and variables (letters) but NO EQUAL SIGN
(Example: 2x+3)
constraint, inequality, equation, expression, angle
expression

x=34
7x=119
x=17
write y is less than 100 as an inequality
y < 100
Which president survived an assassination attempt 69 days into his term?
Joe Biden, Barack Obama, Franklin D. Roosevelt, Ronald Reagan
Ronald Reagan
A mathematical sentence that shows the relationship between quantities that are NOT equal (Example words: greater than, less than; look like alligator mouths)
constraint, inequality, equation, expression, angle
inequality
n-61= 14
n=
2.4x=33
x=13.75
Give me an answer that t could be if the inequality says
t>3
any number bigger than 3 would be correct.
