Chloe swam 40 laps in the pool, but this was only 50% of her total swimming workout. how many more laps does she still need to swim?

40

Step-by-step explanation:

50% is equal to 1/2 so if we multiply 40 by 2 you get 80 then subtract what she already did and you get 40.

hope this helped

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
