Bianca wrote the steps for her solution to the equation 2.3 + 8(1.3x – 4.75) = 629.9. she left out the description for the last step.

what is the missing step of her solution?

add 10.4 to both sides.
add negative 10.4 to both sides.
multiply both sides of the equation by 10.4.
divide both sides of the equation by 10.4.

I believe dividing is always the last step.

Option 4th is correct  the last step would be divide by 10.4 to get the value of x.

Step-by-step explanation:

We have been given an expression:

2.3+8(1.3x-4.75) =629.9  

We will solve the above equation for x

First distribute the parenthesis  over 8 we get:

2.3+10.4x -38=629.9

Now, subtract 2.3 on right hand side of the above equation we get:

10.4 x -38 =629.9-2.3

10.4 x=627.6+38

10.4 x=665.6

Hence, the last step would be divide by 10.4 to get the value of x

therefore, option 4th is correct.

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
