Answer:
The first term should be positive
She did not distribute the -4 properly
She added [tex]\frac{2}{7}[/tex] to negative -4 instead of multiplying
Step-by-step explanation:
In order to tell where she is wrong we should solve the question our selves. we are going to get the following......
[tex]-4(-3x + \frac{2}{7})= -4(-3x) + (-4)(\frac{2}{7} )= 12x - \frac{8}{7}[/tex]
So now we see that the three things she did wrong are.
The first term should be positive
She did not distribute the -4 properly
She added [tex]\frac{2}{7}[/tex] to negative -4 instead of multiplying
Hope this helps :)
Answer:
1, 4
Step-by-step explanation:
1. the product of two negatives are positive and they didn't do that, so yes.
2. the second term should NOT be positive, so they are correct on that.
3. they distributed the -4 correctly but added wrong, so they are correct on that.
4. -4+2/7=3 5/7 2/6(-4)=-4/3. They added instead of multiplying, so they are wrong.
5. they did simplify completely. they just did it wrong.

The perimeter of this shape is 30 feet. What is the length of the missing side?
Answers
Answer:
The answer is 4ft.
Step-by-step explanation:
If you add:
7ft + 3ft + 5ft + 11ft = 26ft
Then if you take away the whole perimeter of the shape by the sides added so far:
30ft - 26ft
It would equal:
30ft - 26ft = 4ft
4ft is the answer.
The value of the length of the missing side is 4 ft and this can be determined by using the arithmetic operations.
Given :
The perimeter of this shape is 30 feet.
The following steps can be used in order to determine the length of the missing side:
Step 1 - The arithmetic operations can be used in order to determine the length of the missing side.
Step 2 - Let the length of the missing side be 'x'.
Step 3 - So, the perimeter of the given figure is given below:
[tex]30 = x+ 7 +3+5+11[/tex]
Step 4 - Simplify the above expression in order to determine the value of 'x'.
[tex]x=30-26\\x = 4[/tex]
So, the value of the length of the missing side is 4 ft.

Explain when it is appropriate to use a benchmark percent in solving a problem.
Answers
Answer:
The most common benchmark percents are 0%, 10%, 25%, 50%, 75% and 100%.
These benchmark values are sometimes used when estimating a solution involving percentages.
Real-World Example
If an item costs $36.00 and there is a 7% sales tax, the benchmark of 10% can be used to mentally estimate the sales tax of the item.
10% of 36, done mentally, is 3.6.
Since 7% is a bit less than 10%, the sales tax will be a bit less than $3.60.Step-by-step explanation:

For the sum of (5.2 x 10^4 ) and (6.95 x 10^4 ) in scientific notation, why will the power of 10 be 10^5 ?
Answers
Answer:
12.15 *10^4
=1.215 *10^5
it must be like that so as to express it in standard form
The sum of (5.2 × 10⁴) and (6.95 × 10⁴) in scientific notation will be 12.15 × 10⁴.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The numbers in the scientific notation will be given as,
(5.2 × 10⁴) and (6.95 × 10⁴)
Then the sum of the numbers will be
⇒ (5.2 × 10⁴) + (6.95 × 10⁴)
⇒ (5.2 + 6.95) × 10⁴
⇒ 12.15 × 10⁴
The sum of (5.2 × 10⁴) and (6.95 × 10⁴) in scientific notation will be 12.15 × 10⁴.

A local movie theater sells two bag sizes of popcorn. Both bags are in the shape of a rectangular prism. Bag A measures 4" long, 3.5" wide and 6" tall. Bag B holds twice as much popcorn as Bag A. If Bag B is 8" long and 3" wide, how tall is Bag B?
Answers
Answer:
the height of bag b is 7
Step-by-step explanation:
first, find the volume of bag a.
volume formula:
length * width * height = volume
length = 4
width = 3.5
height = 6
substitute the values into the formula
4 * 3.5 * 6 = volume
84 = volume
the volume of bag A is 84
next, find the height of bag b
volume formula:
length * width * height.
length = 8
width = 3
volume = 168 (84 * 2)
8 * 3 * h = 168
24h = 168
24h/24 = 168/24
h = 168/24
h = 7
the height of bag B is 7
