a truck holds at most 20.000 lb. there are 18 boxes on the truck. eaxh weighs 750 lb. how many additional boxes can the truck hold? graph the solution show your work

6

Step-by-step explanation:

750 x 18 = 13,500lb

Remaining weight until truck is full = 20,000 - 13,500 = 6,500

6,500 ÷ 750 = 8.66666666667

You cannot have 8.666... of a box and therefore, the answer = 6

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
