i need help factoring polynomials and knowing the steps to reach the answer. 1) x² - 7x + 10 as well as 2) 6r² + 19r - 20

Answer:

40000 and 12.5% respectively

Step-by-step explanation:

soln:

given,

cost price(c.p)=320000

selling price(s.p)=280000

loss(l),loss percentage(l%)=?

we know,

l=c.p-s.p

or,l=320000-280000

•°•l=40000

now,

l%=l/c.p*100%

or,l%=40000/320000*100%

•°•l%=12.5%

Answer:

Step-by-step explanation:

307 divided by 7 is the number of students in each bus with the remainder 6. As the 6 students cannot be fit into the bus and had to travel by car.

Thus we can conclude that:

307= 7x + 6 (6 extra students)

Take away 6 on both sides

7x = 301

i hope this helps i tried my best

x= 43

There are 43 students on each bus.

Answer:

62 people on each bus

Step-by-step explanation:

316-6=310.

310÷5=62 so there will be 62 people riding on each bus.

Answer:

D is the answer

Step-by-step explanation:

A filled circle means "or equal to" in which this case the symbol is less than or equal to, making the dot filled. Since 2 is greater than x, the line would start on the two and continue farther down the line to show that anything 2 or greater is more than x.

Answer:

Answer:

2

Step-by-step explanation:

We will use the KFC method to figure out the answer:

3/5 ÷ 2/1

We keep the first fraction

3/5 ÷ 2/1

Flip the last fraction (swap the numbers)

3/5 ÷ 1/2

Change the sign (to a multiplication symbol)

3/5 x 1/2

Then, finally, to solve for the answer, we multiply across (3 x 1 and 5 x 2).

3 x 1 = 3

5 x 2 = 10

The answer is 3/10 because it cannot be simplified any further.

letters = 46536

Answer:

-6

Step-by-step explanation:

Plug in (-1) for y: -3(-1) - 9

Simplify: Negative x Negative = Positive

-3(-1) = 3 so... 3-9

3 - 9 = -6

-3y - 9 is equivalent to -6

Answer:

Step-by-step explanation:

-3(-1)-9

3-9=-6

-6≠-9

-6 is not equivalent to -9

The solution is Option C.

The value of the number 2,070,000 written in scientific notation is

A = 2.07 x 10⁶

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as A

Now , the value of A is

A = 2,070,000

Now , to write the number in scientific notation ,

Multiply the number 207 with powers of 10

So , the value of A will be

A = 207 x 10⁴

Now , the number 207 can be written as 2.07 x 10²

On simplifying the equation , we get

A = 2.07 x 10² x 10⁴

A = 2.07 x 10²⁺⁴

A = 2.07 x 10⁶

Therefore , the value of A is 2.07 x 10⁶

Hence , the value of the number is 2.07 x 10⁶

Answer:

$3.53

Step-by-step explanation:

hot dogs = $1.25 each

2 hot dogs = 1.25 × 2

= $2.50

A serving of onion rings = $2.99

Drink = $0.98

Total amount with Karen = $10.00

how much change will Karen receive?

Total cost = 2 hot dogs + A serving of onion rings + Drink

= $2.50 + $2.99 + $0.98

= $6.47

Karen's change = Total amount with Karen - Total cost

= $10.00 - $6.47

= $3.53

Answer:

x=-1

Step-by-step explanation:

3(x−4)=15x

Use the distributive property to multiply 3 by x−4.

3x−12=15x

Subtract 15x from both sides.

3x−12−15x=0

Combine 3x and −15x to get −12x.

−12x−12=0

Add 12 to both sides. Anything plus zero gives itself.

−12x=12

Divide both sides by −12.

x=  

−12

12

​  

Divide 12 by −12 to get −1.

x=−1

Answer:

[tex]3(x- 4)=15x[/tex]

[tex]3x-12=15x[/tex]

[tex]3x-12+12=15x+12[/tex]

[tex]3x=15x+12[/tex]

[tex]3x-15x=15x+12-15x[/tex]

Answer:

is the answer 7ft?

Step-by-step explanation:

i am not completely sure

Set up a ratio of the height over the distance to the mirror/

X/5 = 28/7

Cross multiply:

7x = 140

7? = 140

Divide both sides by 7

? = 140/7

? = 20

The answer is 20 feet

10

The slope of all parallel lines is equal. 10 is the slope in the equation y = 10x - 20, so the slope of a line parallel to it has to be 10 also.

Answer:

yes it's on a 1.5 scale factor.....I think. The question you put at the top threw me off at first but the picture makes sense. I'm not entirely sure if this is right but if you adjust the triangle to be the same way as the other one then you will see which sides correspond to each other. Each number can be multiplied by 1.5 to get the number that is on the side of the other triangle that corresponds with it....if that makes any sense
