What’s 3 11/12 - 1 4/12

2 7/12

Step-by-step explanation:

1st do 3-1=4

1112−412=?

The two fractions have like denominators so you can subtract the numerators.

Then:

11−412=712

This fraction cannot be reduced.

Therefore:

1112−412=712

Solution by Formulas

Apply the fractions formula for subtraction, to

1112−412

and solve

(11×12)−(4×12)12×12

=132−48144

=84144

Reduce by dividing both the numerator and denominator by the Greatest Common Factor GCF(84,144) = 12

84÷12144÷12=712

Therefore:

1112−412=712

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
