Answer: Turbo jet pack: 6d + 7; x-ray vision glasses: 2d-5; Invisible shield: 10d + 1
Step-by-step explanation:
There’s not really any math needed because it’s put into words.
I will show you how to do first one but it is simple addition and subtraction.
7y + 5 + (3 - y)
We just combine like terms
7y - y + 5 + 3
6y + 8
I will do the second one for subtraction
5 + 5q - (3q - 9)
since the subtracroon sign is outsiDr patenthesis you have to apply it to both terms
5 + 5q - 3q + 9
since it was -9 it became --9 which is +9
so:
5q - 3q + 5 + 9
2q + 14
