What type of answer will 2.25 + .75 have? explain.

the answer will have a decimal but there is no such thing as type of answer.

there are many ways to answer this

It will have a whole number answer of 3

Step-by-step explanation:

When you ad the 2 numbers you start with the number farthest to the right. So you add 5 and 5 to get 10. You then carry the 1 and now you add 1+2+7. First just add the 7 and the 2 to get 9. Add the 1 after that and you get 10 again. Carry the 1 onto the 2 and now you have 2+1. 2+1= 3

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

b. 2 and 4
