Kim has stamps only from the u. s. and france in her collection. she has 4 times as many stamps from the u. s. as france. which is an expression for the number of stamps in her collection using f for the number of stamps from france?

f

4+ f

4f

5f

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

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
