It takes cindy 3/4 of an hour to complete a puzzle how many puzzles can cindy finish in three hours

She can finish 4 puzzles.

Step-by-step explanation:

3/4+3/4=1 1/2

1 1/2+ 1 1/2= 3(hours)

That means that there are four 3/4s and that also means she does 4 puzzles in 3 hours.

Hope this helps!^_^

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.
