Noah says that 9x − 2x + 4x is equivalent to 3x because the subtraction sign tells us to subtract everything that comes after 9x

.
Elena says that 9x − 2x + 4x is equivalent to 11x because the subtraction only applies to 2x.



Do you agree with either of these claims?

Answer:

Noah's claim is correct

Step-by-step explanation:

B O D M A S - Brackets, Over, Division, Multiplication, Addition and Subtraction, this means that you must do the addition first.  

2x+ 4x = 6x

9x - 6x = 3x

Noah is correct as the - sign tells us that you have to subtract everything after the 9x

Hope this is ok and helps a little bit

How to solve (8.76 x 109)(6.52 x 10-3)/13.27 x 105?
SVEN [57.7K]
Use PEMDAS:
P = parenthesis
E = exponents
M = multiplication
D = division
A = addition
S = subtraction


First, start with the parenthesis:
(8.76 * 109)(6.52 * 10 - 3) / 13.27 * 105
(954.84)*(62.2) / 13.27 * 105

Then do ALL multiplication:
59,391.048 / 1,393.35

Now do all division:
42.62

So, your final answer is 42.62

Without sketching the graph, find the x intercepts and y-intercepts of the graph of the equation 2x+3y=12 What isjare the x-inte
den301095 [7]

Answer:

x-intercept: (6,0)

y-intercept:  (0,4)

Step-by-step explanation:

The x-intercepts lay on the x-axis and therefore their y-coordinate is 0.

To find the x-intercept, you set y to 0 and solve for x.

2x+3y=12

Set y=0.

2x+3(0)=12

2x+0    =12

2x         =12

Divide both sides by 2:

 x          =12/2

 x          =6

The x-intercept is (x,y)=(6,0).

The y-intercepts lay on the y-axis and therefore their x-coordinate is 0.

To find the y-intercept, you set x to 0 solve for y.

2x+3y=12

2(0)+3y=12

0+3y    =12

3y         =12

Divide both sides by 3:

 y          =12/3

 y           =4

The y-intercept is (0,4).

A recipe includes 66 cups of flour and two thirds 2 3 cup of buttermilkbuttermilk. Write the ratio of the amount of flour to the
beks73 [17]

Answer:

The ratio of the amount of flour to the amount of buttermilk=99:1

Step-by-step explanation:

Step 1: Determine quantity for each recipe

Quantity of flour=66 cups

Quantity of buttermilk=2/3 cups

Step 2: Calculate the total quantity of recipe

The expression for the total quantity is;

T=f+b

where;

T=total quantity of recipe

f=quantity of flour

b=quantity of buttermilk

In our case;

T=unknown

f=66 cups

b=2/3 cups

replacing;

T=(66)+(2/3)=66 2/3 cups

Step 3: Determine fraction of each

fraction of buttermilk=(2/3)/(66 2/3)=1/100

fraction of flour=66/(66 2/3)=99/100

Step 4: Determine ratio of flour to buttermilk

Amount of flour:amount of buttermilk

(99/100):(1/100)

The ratio of the amount of flour to the amount of buttermilk=99:1
