Seven students cut 5 3/4 inches of thread from a spool for a school project. what number represents the change in the amount of the thread on the spool?
a.) -40 1/4b.) -35 3/4c.) -29 3/4d.) -26 1/4

The Option A is correct.i.e.,  

Step-by-step explanation:

Given: Length of thread a student cuts = inches

           total no. of student that cut thread = 7

To find: Number which represent change in amount of thread on spool.

Length of thread a student cuts =

                                                     =

                                                     = inches

Length of thread 7 student cuts =

                                                     =

                                                     =   inches  (Coverting into mixed fraction)

So, negative of length  that 7 student cut from spool is the number represent change in amount of thread.

Therefore, The Option A is correct.i.e.,  

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
