A. make a table, chart or list
B. work backwards
C. use a formula
D. look for a pattern

b

Step-bystep explanation:

when subtracting you could reverse it and add so add back the 2.50 to the 5 and if he spent half of what he had left the that would mean he had another 5 dollars. in total he had 12.50$

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
