How do you know the correct order in which to evaluate algebraic expressions?

6 0

To evaluate algebraic expressions there is no order. You just need to follow something called pemdas. The way to remember this is

p = please
e = excuse
m = my
d = dear
a= aunt
s = sally

So just remember Please excuse my dear aunt sally or pemdas.

P = parentheses (Apply from left tor right)
E = exponent (Apply from left tor right)
M = multiplication (Apply from left tor right)
D = division (Apply from left tor right)
A = addition (Apply from left tor right)
S = subtraction (Apply from left tor right)

Then solve!

Hope this helps!! xD

In solving algebraic expressions, there is an order in which to solve it.

1) perform the operation inside the parenthesis first
2) then perform the operation with the exponents
3) apply multiplication and division from left to right of the equation.
4) apply addition and subtraction from left to right of the equation.

Remember this: PEMDAS for easier recall. (parenthesis, exponents, multiplication, division, addition, subtraction)

What is the coefficient of (-2/3x)(3y)(-2x)

dolphi86 [110]

Answer:

The coefficient is equal to $4$

Step-by-step explanation:

we have

$(-\frac{2}{3}x)(3y)(-2x)$

we know that

The coefficient is equal to

$(-\frac{2}{3})(3)(-2)=4$

$(-\frac{2}{3}x)(3y)(-2x)=4x^{2}y$

The office manager of a small office ordered 140 packs of printer paper based on average daily use, she knows that the paper wil

Mandarinka [93]

slope intercept form is y=mx+b

So slope intercept form is The office manager of a small office ordered 140 packs of printer paper based on average daily use, she knows that the paper will last about 80 days

(A) Lets make a table

X axis represents the Number of days paper used

y axis represents the packs of printer paper used

x y

days packs of printer paper used

0 0 (0 days , 0 packs used)

80 140 (in 80 days , 140 packs paper used)

The graph is attached below

(B) To find Equation of a line we use points (0,0) and (80,140)

$slope = \frac{y_2-y_1}{x_2-x_1} = \frac{140-0}{80-0} = \frac{7}{4}$

y intecept is (0,0)

so b= 4

Slope intercept form of a line i y=mx + b

m is the slope and b is the y intercept

So slope intercept form of line becomes

$y= \frac{7}{4} x$

Standard form is Ax + By =C

$y= \frac{7}{4} x$

Multiply both sides by 4

4y = 7x

Now subtract 7x on both sides

-7x + 4y =0 is the standard form

$y= \frac{7}{4} x$

$y= \frac{7}{4}(30)= 52.5$

Total 140 packs of printer paper

52.5 packs of paper used

Packs of paper remaining after 30 days = 140- 52.5= 87.5
