Answer:

2 3/4

3 5/28

Step-by-step explanation:

First, Find the common denominator of 4 and 7 which is 28. 28 will be the denominator of your difference.Then, now time to multiply, now you multiply 7 by 21 because you multiplied 7 by 4 to get 28. You do the same for the others one but a bit different because this time you multiply 4 by 3= 12 now you have 21/28 and 12/28. Now you add 21 and 12 not 28 because you don't multiply denominators in this case. After that you get 33/28, this is an improper fraction so you divide. 28 goes into 33 once so you have a whole number 1 then you have 5 left over making it the numerator. Result 1 5/28, because you have the whole number 2 left from the equation you add it ending up with 3 5/8

Hope this helps :D !!

Evaluate 3^2 + (5-2) X 4 - 6/3

muminat

Answer:

The result is 19

Step-by-step explanation:

$3^{2} + (5-2)x4 - 6/3$

Step 1: Parenthesizing (5-2)=3

$3^{2} + 3x4 - 6/3$

Step 2: Exponentiation $3^{2}=9$

$9 + 3x4 - 6/3$

Step 3: Multiplication and division 3x4=12 and 6/3=2

$9 + 12 - 2$

Step 4: Addition and subtraction 9+12=21, and 21-2=19

21-2

The operations are ordered from highest to lowest in the order:

1. Parenthesizing,

2. Factorial,

3. Exponentiation,

4. Multiplication and division,

5. Addition and subtraction.

Hope this helps!

What is the slope of the line that contains these points?

seraphim [82]

Answer:

Step-by-step explanation:

The slope =

difference in y coordinates of 2 points / difference in coordinates of corresponding x coordinates.

So taking the first 2 points:

The slope = (18-10) / 0 - (-1)

= 8/1

= 8.

This is confirmed by slope between the second and third points

slope = 26-18/ (1-0) = 8.
