Zander bought 3 hats for $7 each and 2 shirts for $9 each. How much did Zander spend

16

Step-by-step explanation: because you add $7 and $9 together

39

Step-by-step explanation:

If Zander bought 3 shirts you are multiplying 7 and 3 which gives you 21 so he bought 3 hats for $21 and then he spent 9 dollars on 2 shirts so 9 times 2 which gets you $18 so then you do $21+$18 which gives you the answer which is 39

c is the correct answer

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
