If matrix A is a 3x4 and matrix B is a 5x3, what are the dimensions of BA?

I don't know if this is right but 27

Step-by-step explanation:

Because 3 x 4 = 12 so that's A, and 5 x 3 = 15 so that's B. Add them together and get 27 for BA

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
