2Y - 1.7 =3.3 <br><br> HELP !!!!!
bogdanovich [222]

Answer:

2.5

Step-by-step explanation:

Simplifying

2y + -1.7 = 3.3

Reorder the terms:

-1.7 + 2y = 3.3

Solving

-1.7 + 2y = 3.3

Solving for variable 'y'.

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

Add '1.7' to each side of the equation.

-1.7 + 1.7 + 2y = 3.3 + 1.7

Combine like terms: -1.7 + 1.7 = 0.0

0.0 + 2y = 3.3 + 1.7

2y = 3.3 + 1.7

Combine like terms: 3.3 + 1.7 = 5

2y = 5

Divide each side by '2'.

y = 2.5

Simplifying

y = 2.5

Please answer below :-)
Serjik [45]

Answer:

B. 88.8

Step-by-step explanation:

let x represent class y

(x+71.2)/2=80   multiply each side by 2

x+71.2=160      subtract 71.2 by both sides

x=88.8

or

trial an error

replace x with each of the numbers and see if it plugs in.

example:

(80.5+71.2)/2=80

151.7/2=80

75.85=80?

false. incorrect

another example:

(88.8+71.2)/2=80

160/2=80

80=80?

true. correct
