Find the sum of (8a + 2b - 4 ) and ( 3b - 5 )
please help !!!

Step-by-step explanation: (8a + 2b + -4) = (3b + -5)

Reorder the terms:

(-4 + 8a + 2b) = (3b + -5)

Remove parenthesis around (-4 + 8a + 2b)

-4 + 8a + 2b = (3b + -5)

Reorder the terms:

-4 + 8a + 2b = (-5 + 3b)

Remove parenthesis around (-5 + 3b)

-4 + 8a + 2b = -5 + 3b

Solving

-4 + 8a + 2b = -5 + 3b

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 8a + 4 + 2b = -5 + 4 + 3b

Reorder the terms:

-4 + 4 + 8a + 2b = -5 + 4 + 3b

Combine like terms: -4 + 4 = 0

0 + 8a + 2b = -5 + 4 + 3b

8a + 2b = -5 + 4 + 3b

Combine like terms: -5 + 4 = -1

8a + 2b = -1 + 3b

Add '-2b' to each side of the equation.

8a + 2b + -2b = -1 + 3b + -2b

Combine like terms: 2b + -2b = 0

8a + 0 = -1 + 3b + -2b

8a = -1 + 3b + -2b

Combine like terms: 3b + -2b = 1b

8a = -1 + 1b

Divide each side by '8'.

a = -0.125 + 0.125b

Simplifying

a = -0.125 + 0.125b

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
