Answer:

5 7/24

Step-by-step explanation:

First, you need to make the denominators the same. When you multiply 6 with 4 you get 24, and if you multiply 8 with 3 you get 24. Then you have to multiply the numbers you multiplied with the denominators with the numerator. So, 5 x 4 is 20 and 3 x 1 is 3. Once you put all the numbers together it should look like this: 3 20/24 and 9 3/24. In order to find the answer, you have to subtract the numbers from each other. Which would look like this: 9 3/24 - 3 20/24. But as you can see you can't subtract 3 from 20. So you have to carry the 9. This means you have to subtract 9 from 1, and then you have 27 for the numerator, this then makes it possible to subtract from 20. So then the fractions subtracted from each other is 7 and the whole numbers subtracted from each other is 5 (because the 9 is now 8 since we subtracted one from it). Whole numbers subtracted from each other: 5. Fractions subtracted from each other: 7/24. Add it together you get 5 7/24.  

Numerator - the number above the fraction, ex 3 in 3/4

Denominator - the number below the fraction, ex 4 in 3/4

This question is the on I need help with
allsm [11]

let's recall that there are 16oz in 1 lbs, so then 12lbs is 12*16 = 192oz, plus 5, that makes it 197oz, so then 12lb 5oz is really 197oz.

likewise, 7lb is 7*16 = 112oz, plus 10 that makes it 122oz.

197 - 122 = 75 oz

and 75 oz is just 16+16+16+16+11, 4lbs and 11 oz.

just olya [345]

Answer:The first one is 2.333333333

Step-by-step explanation:Simplifying

5(2 + -1j) + (2j + -3) = 0

(2 * 5 + -1j * 5) + (2j + -3) = 0

(10 + -5j) + (2j + -3) = 0

Reorder the terms:

10 + -5j + (-3 + 2j) = 0

Remove parenthesis around (-3 + 2j)

10 + -5j + -3 + 2j = 0

Reorder the terms:

10 + -3 + -5j + 2j = 0

Combine like terms: 10 + -3 = 7

7 + -5j + 2j = 0

Combine like terms: -5j + 2j = -3j

7 + -3j = 0

Solving

7 + -3j = 0

Solving for variable 'j'.

Move all terms containing j to the left, all other terms to the right.

Add '-7' to each side of the equation.

7 + -7 + -3j = 0 + -7

Combine like terms: 7 + -7 = 0

0 + -3j = 0 + -7

-3j = 0 + -7

Combine like terms: 0 + -7 = -7

-3j = -7

Divide each side by '-3'.

j = 2.333333333

Simplifying

j = 2.333333333
