12. Let's factor x2−9x+8

x2−9x+8

The middle number is -9 and the last number is 8.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -9

Multiply together to get 8

Can you think of the two numbers?

Try -1 and -8:

-1+-8 = -9

-1*-8 = 8

Fill in the blanks in

(x+_)(x+_)

with -1 and -8 to get...

(x-1)(x-8)

15. Let's solve your equation step-by-step.

(x−2)(x−3)=2

Step 1: Simplify both sides of the equation.

x2−5x+6=2

Step 2: Subtract 2 from both sides.

x2−5x+6−2=2−2

x2−5x+4=0

Step 3: Factor left side of equation.

(x−1)(x−4)=0

Step 4: Set factors equal to 0.

x−1=0 or x−4=0

x=1 or x=4

Sorry I wasn't able to do 13 and 14 but hope this helps! :)

Answer:

x + y = 1042

1.50x + 0.75y = 1140

Step-by-step explanation:

If there was a total of 1,042 fares paid then x + y would be equal to that because x is the number of regular fares paid and y is the number of reduced fares paid.

If there was a total of $1,140 made from the fares then we can use 1.50x + 0.75y. We put the 1.5 in front of the x because each fare paid costs $1.50, same with Y each reduced fare paid is $0.75. So both of those need to be added up to get $1,140.

Answer:

x < -7

Step-by-step explanation:

2(4x + 1) < 3(2x - 3)

Distributive Property:

8x + 8 < 6x - 6

Subtract on Both Sides:

8x + 8 < 6x - 6

- 6x       -6x

--------------------

2x + 8 < - 6

      -8    -8

---------------

2x < -14

Divide on Both Sides:

2x < -14

Answer:

17 miles away

Step-by-step explanation:

if you draw, you get a right angle triangle.

use pythagorean theorem

c² = a²+b²

c² = 15² + 8²

c² = 225 + 64

c= sqrt(289)

c = 17

Answer:

Orange rose = 2/9

Step-by-step explanation:

In order to find probability of picking one item, you add all the possible things you could choose. So, 3+2+4 equals a total of 9 outcomes, and that would be your denominator for your fraction of probability. From there it's really easy. Just put the amount of things your trying to find the probability for in the numerator spot.

Ex.

There are 9 total roses so that would be the denominator (?/9)

To find out the probability for picking an orange rose, you'd put the 2 in as the numerator because that is the total number of orange roses you have (2/?)

Then just put the two together (2/9).

Step-by-step explanation:

getcalc.com's fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.

50/400 0.125 12.5%

49/400 0.1225 12.25%

48/400 0.12 12%

47/400 0.1175 11.75%

Answer:

fraction to decimal calculator to find what's an equivalent decimal for the fractional number 48/400.

0.12 is a decimal and 12/100 or 12% is the percentage for 48/400.

Step-by-step explanation:

A fraction consists of two numbers and a fraction bar:

48/400

The number above the bar is the numerator: 48

The number below the bar is the denominator: 400

Divide the numerator by the denominator to get fraction's value:

Val = 48 ÷ 400

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% = p/100 = p ÷ 100.

Calculate fraction's value.

Divide the numerator by the denominator to get fraction's value:

48/400 =

48 ÷ 400 =

0.12

Note:

100/100 = 100 ÷ 100 = 100% = 1

Multiply a number by the fraction 100/100,

... and its value doesn't change.

Calculate the percent value:

0.12 =

0.12 × 100/100 =

(0.12 × 100)/100 =

12/100 =

12%;

Answer:

  10^3, 0.001

Step-by-step explanation:

Given:

  1/(10×10×10)

Find:

  The equivalent representations among the options ...

  10^-3, 0.01, 0.001, 10^3

Solution:

The denominator is 10×10×10 = 1000, so the fraction is 1/1000.

The decimal representation of that is 0.001. In exponential form, it is ...

  1/10^3 = 10^-3

Equivalents among the offered choices are 10^-3 and 0.001.

Answer:

eric = 15

chris 7

Step-by-step explanation:

Let the questions Chris answered correctly be represented by c

Let the questions Eric answered correctly be represented by e

They both got 22 questions right. This can be represented by this equation :

c + e = 22 --- eqn 1

Chris scored 8 less than Eric. This can be represented by this equation :

c = e - 8 --- eqn 2

Substitute for c in eqn 1  

e - 8 + e = 22 .

collect like terms

2e = 30

solve for e

e = 15

Substitute for e in eqn 2

c = 15 - 8 = 7
