j = 5

Step-by-step explanation:

-3 would have to be -3/1 or 3/-1

y1-y2 -3-6

____ _____

x1-x2 -2

-9/-2 we need -9/3 to get to -3 so if we substitute =the blank for 5, -2 +5 is 3 and we get the answer

How many 1-in. cubes can fit into a 2 by 4 by 2 in.<br>prism?

wel

Answer:

Step-by-step explanation:

The dimensions of the base of the prism are 4" by 2"; the height is 2".

Looking at the base, we see that (4)(2), or (8) 1" cubes would cover it exactly and wholly. We'd have a 3-dimensional prism with one layer of 1" cubes.

Now if we add a second layer right on top of the first layer, we'd have used (16) 1" cubes.

2 1/4 ⋅ 1 2/3<br> as a mixed number

Gemiola [76]

Answer:

$3\frac{3}{4}$

Step-by-step explanation:

We have two mixed numbers and are asked to multiply them together.

2 1/4 * 1 2/3

First we convert the mixed numbers into improper fractions to make it easier for us. So follow the MA rule.

Multiply the whole number by the denominator and add the numerator.

2 1/4 * 1 2/3

9/4 * 5/3

Now multiply across,

$\frac{9*5}{4*3}$

$\frac{45}{12}$

Now we need to convert this back into a mixed number.

So how many times does 45 go into 12?

3 times, and 3 are left.

$3\frac{3}{4}$
