Help ?//////////////
Alik [6]
The correct answer is that Hector placed Puppy 3 at -3.4 instead of at -0.75.
So A would be your correct answer. -3/4 is equivalent to -0.75. Think of it like money. 4 quarters equals $1.00. 3 quarters is 75 cents, or .75 which is this. Don’t forget the signs though. God bless you.

Uhh help lol<br> 5.3x + y = 28.5 <br> 4.2x + 3.1y = 27.2<br> find x and y
navik [9.2K]

Answer:

x = 5, y = 2

Step-by-step explanation:

First, isolate y in the top equation.

y = -5.3x+28.5

Next, substitute y in the bottom equation.

4.2x + 3.1(-5.3x + 28.5) = 27.2

5.3x + y = 28.5

Simplify.

4.2x + -16.43x + 88.35 = 27.2

Combine like terms.

-12.23x + 88.35 = 27.2

Isolate x on one side.

-12.23x = -61.15

Isolate x.

x = 5

Substitute x into 5.3x + y = 28.5

5.3(5) + y = 28.5

Simplify.

26.5 + y = 28.5

Isolate y.

y = 2

x = 5 \\y = 2
