The molina family went to a concert together. they got 4 concert tickets for 25$ each ,3 t shirt for 15$ each and a poster for 10$ write an expression for the total cost then find the total cost

4(25) + 3(15) +10 = $155

Step-by-step explanation:

first you plug in the information so since there are 4 tickets for $25 each, that part of the expression would be 4(25). Next you add the t-shirts so since there are three for $15 each that part of the expression would be 3(15). Lastly you add the poster. since there is only one and it costs $10 you would just add 10. This makes your expression 4(25) + 3(15) +10. (the parenthesis mean you multiply the number inside by the number outside).

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
