Find the error in the solution, and then solve it correctly.

We could find the error first, but if we solve the equation, we can compare our answers to find the error. So,

7x + 12 + 3x = 8

10x + 12 = 8

10x = -4

x = -4/10

x = -2/5.

When we compare the two, we see that our second line is vastly different, and we can easily isolate the mistake, finding that it occurs when they disregard the variable in the 3x term and subtract 8 by 3 rather than combining the terms 3x and 7x together.

Answer:

x=-4/10 = -2/5

Step-by-step explanation:

7x+12+3x=8

(7x+3x) =8-12

10x=-4

x=-4/10

x= -2/5

Joe, Luis, Albert and Lupe want to share 3 oranges so that everyone gets an equal amount. How much orange will each child get? ~
Blababa [14]

Answer:

Half an orange

Step-by-step explanation:

It would be half an orange because it says 4 other people. Joe, Luis, Albert, and Lupe. And it says 3 oranges so that everyone would get an equal amount. So if you think about it, theirs no other way to let everyone have an equal piece. So you would have to split them in half and through the left overs away that cant be shared.

zzz [600]

Answer:

7.125

Step-by-step explanation:

Convert each fraction to a decimal  

1/4=.25 = 8.250

1/2=.5 = 6.500

5/8=.625 = 6.625

Then, add all of them together

8.250+6.500+6.625=21.375

Lastly, divide by 3 because that's how many values you have

21.375/3=7.125
