Charlie has installed 65% of the tiles for a tile floor. If he installed 120 tiles how many tiles are there total?

185 tiles

Step-by-step explanation:

120÷65=1.846...

1.846...×100=184.615...

round up=185

185

Step-by-step explanation:

let total tiles be x

x of 65% =120

65x/100 = 120

65x= 12000

x= 184.62~185

answer: ouch. thats difficult

step-by-step explanation:

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
