Answer:

£800

Step-by-step explanation:

when you recuce the price of something by 30%, it is 70% of the original (100% minus whatever percent reduction).

.7x=560 where x is the original price of the tv

560/.7=800

I need help with this problem and would really appreiciate a short explanation too.<br> 15 PTS
inysia [295]

okay. the point has an x and y value. place them into the equation.

1=m(1)+b

m=slope, and theequation tells you that slope is 7.

1=7(1)+b

now you need to figure out what b is.

1=7(1)+b

^

1= 7 +b

-7 -7

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

-6=B

b is 6. now place it into the equation, replacing the x and y values back.

y=7x-6.

write 7 and 6 in the boxes (the negative for the six has already been provided)

nignag [31]

Answer:

Step-by-step explanation:

Note that one equation has -2y and the other has +2y. The fastest solution is to add the equations together. The two  terms will cancel out, eliminating the y terms.

Nikolai has a jar filled with 120 marbles. he has 72 red marbles, 17 blue marbles, 13 green marbles, and 18 purple marbles. what
asambeis [7]
To find the probability of both of these occurring, you will multiply the probability of choosing a blue marble by the probability of choosing a purple marble (with no replacement after the first one).

Probability of choosing a blue marble:  17/120
Probability of choosing a purple marble: 18/119

17/120 x 18/119 = 3/140

You will have a 3/140 chance of both of these occurring.

The measures of the angles of a triangle are in the extended ratio 4 : 5 : 6. What is the measure of the smallest angle?
anyanavicka [17]
<span>The sum of the interior angles of a triangle is 180 degrees
</span>
4x + 5x + 6x = 180
15x = 180
x = 180/15
x = 12

<span>The measure of the smallest angle = 4x = 4*12 = 48</span>°
