Julia worked 15 hours more than james last month. if julia worked 8 hours for every 4 hours that james worked how many how’s did they each work

Step-by-step explanation:

Julia worked 8 hours for every 4 hours that James worked.  This  shows that for every hour James work, Julia works double the time ie . 2 hours.

Julia worked 15 hours more than James last month.

Julia worked 30hours and James worked 15 hours

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

why can't you?
