Answer:
A literal equation is an equation which consists primarily of letters. Formulas are an example of literal equations.
About 10 songs because if you add up all ten numbers of all the songs then you divide, then you divide again you will get 10 songs
25 because $518 ( their total ) divided by $21 ( the amount for EACH uniform) is 24.6 which isn’t possible so round it to 25
Multiply both sides by 2 to clear the fraction.
-3x + 6 <= 24
subtract 6 from both sides.
-3 x <= 18
divide both sides by -3, since you're dividing an inequality by a negative number you have to change the direction of the inequality sign.
x >= -6
