Remember to use PEMDAS (Parenthesis, Exponents, Multiply, Divide, Add, Subtract)

Solve Parenthesis first
(12 ÷ 4 + 4)
(3 + 4)
(7)
7 is the value of the part of the expression that should be completed first

Use the order of operations: PEMDAS: parentheses first, then exponents, multiplication, division, addition, subtraction

=18÷360×(12÷4+4)−6+3
working inside the parentheses, do the division first

=(12÷4+4)
=3+4
=7

ANSWER: The parentheses should be completed first. The value inside the parentheses is 7.

Hope this helps! :)

Answer: 5.43

Step-by-step explanation:

To find the Mean, sum the values and divide by the number of values

=9.6 + 2 + 4.1 + 8 + 5.9 +2 + 3.7 + 6 + 7.6/9

= 48.9/9

=5.43

I hope this helps.

What is the slope form equation?
CaHeK987 [17]

Answer:

y= mx +c

Step-by-step explanation:

The point- slope form of an equation is

y= mx +c, where m is the gradient and c is the y-intercept.

You can find the value of m by using the gradient formula.

gradient =  \frac{y1 - y2}{x1 - x2}

Then substitute the value of m found into the equation. Next substitute a pair of coordinates the line passes through to find the value of c. Substitute the value of c and you will obtain the point-slope form equation of the line.

<u>Here's an example.</u>

Point-slope form of an equation passing through (1, 2) and (5, 6).

① Finding gradient, m.

m =  \frac{6 - 2}{5 - 1}  \\ m =  \frac{4}{4}  \\ m = 1

② Substitute value of m into equation.

y= 1x +c

y= x +c

③ Substitute a pair of coordinates.

when x=1, y=2,

2= 1 +c

c= 2 -1

c= 1

Thus the equation of the line is y= x +1.

Could someone please help
ololo11 [35]
Ok so when you add fractions, the denominators have to be the same, therefore: (whole numbers you can still add)

5(1/2)+5(1/2)= 10(2/2), which equals to 11.

5(1/2) is also 5.5, since 1/2 is 50/100.

5.5 + 5.5 = 11
