The school had a budget of $500 to go on the band field trip. The students are selling cakes for $10 each for the rest of the money. The cost of the field trip is more than $1500. Write an inequality that represents the scenario.
$500 + 10x > $1500
What inequality does this represent?
x≤20
What equation does this represent?
x=20
What inequality does this represent?
x<20
Solve: 8x − 1 = 23 − 4x
x = 2
Solve and represent on a number line: 7 -2x < 17
x > -7
Solve: -5 -5x -10 > 25
x< -8
Solve −5x − 7 = 108
x = -23
What is this sign "≤" called?
less than or equal to
What is this sign ">" called?
more than
Solve: 5 + 4x − 7 = 4x − 2 − x
x = 0
