Jackie made an error when trying to determine the value of the expression.
Here are the steps she used. Describe the error that Jackie made.
2/3 (3/5 - 3/4) + 1/2 ➗ 1/4
Step 1: 2/3 (- 3/20) + 1/2 ➗ 1/4
Step 2: - 1/10 + 1/2 ➗ 1/4
Step 3: - 1/10 + 1/8
Step 4: 1/40

help :,)

Answers

Answer 1

Answer: The real answer is 19/10 or 1 and 9/10

Step-by-step explanation:

Jackie added 1/2 and 1/4 to get 1/8 but in order of operation you have to multiply and divide first . So she should have divided 1/2 by 1/4 and then added that with -1/10 .

Step-by-step explanation:

You have 8 cups of flour. It takes 1 cup of flour to make 24 cookies. The function c(f) = 24f
represents the number of cookies, c, that can be made with f cups of flour.

What domain and range are reasonable for the function?

What do the x-intercept and y-intercept of the graph above represent in this situation?

Answers

Answer:

y = c(f) = 24x so range is 24  domain is 1 the  x intercept and y intercept do not count as an adding value in the equation so in order for  y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1

Step-by-step explanation:

Given (1, 24) (8, c(f))  = 24 (8) = 192  = (1, 24) (8, 192)  Then use formula y2-y1/x2- x1 = 192-24/ 8-1 = 168/7 = 24  slope  = 24    equation = (f) = 24x The domain is all values of x that give real numbers as answers, and that is everything except 0, since 1/0 is illegal The range is all the values of y that can be reached from real values of x.

Answer:

y = c(f) = 24x so range is 24  domain is 1 the  x intercept and y intercept do not count as an adding value in the equation so in order for  y = c(f) = 24x we need to make x a condition that x=1 and therefore x represents 1

Answers

Answer:

A. 8

Step-by-step explanation:

Use PEMDAS

E for exponents (4^2)/(2^1)

4^2 = 4 * 4 = 16

2^1 = 2

D for division

16/2 = 8

So the answer is A

Hi!

Let's solve it together.

4^2 is just 4x4,

4 x 4 = 16

Next, 2^1.

2^1 is just 2, so the answer is 2.

Now, we divide 16 and 2.

16 ÷ 2 = 8

So, the answer is A.Hope this helps!~~~PicklePoppers~~~

Rewrite 1/5 barrel 1/2 hour as a unit rate

Answers

The answer is B, 2/5 barrel/hour.

Hope this helps! ☺️

Unit rate of (1 /5 barrel) / (1/2hour) is equals to (2/5) barrels /hour.

What is unit rate?

"Unit rate is defined as the representation of the ratio of the two different units with value of the denominator equals to 1."

According to the question,

Given,

[tex]\frac{\frac{1}{5} barrel}{\frac{1}{2} hour}[/tex]

⇒ (1 / 2) hour = ( 1/ 5) barrel

⇒ 1 hour = ( 2 / 5) barrel

⇒( 2 / 5) barrel per 1 hour

Therefore,

Unit  rate of given value is rewritten as

[tex]\frac{2}{5}[/tex] barrel / hour

Hence, Option(B) is the correct answer.

Answer:  234

=========================================================

Explanation:

The symbol that looks like an "E" is the uppercase greek letter sigma. It's used for summation. Specifically we are adding terms of the form -4+5n. What we do is replace n with values from the set {2,3,4,...,9,10}. After evaluating each item, we add up the results to get our final answer.

If n = 2, then -4+5n = -4+5*2 = 6 which is the first term.

If n = 3, then -4+5n = -4+5*3 = 11 is the second term

and so on until you reach n = 10.

A table is a handy way to keep track of everything (see below). Adding everything in the second column leads to the final answer of 234.

Please help me solve this: y=8x 4x+y=48

Answers

Answer: x=4, y=32

Step-by-step explanation:

y=8x

4x+y=48

Plug in 8x for y in the equation

4x+8x = 48

Add like terms

12x= 48

Divide both side by 12

12x/12=48/12

x= 4

Then plug 4 back into the original equation in place of x

4(4)+y=48

16+y=48

Minus 16 from both sides

y= 48-16

y= 32

Answer: (4,32)

Answer: x = 4

Step-by-step explanation: 48 divided by 12 = 4

4 x 4 = 16

Y = 8x

8 x 4 = 32

32 + 16 = 48
