Alice and Claire go apple picking. When they are done, Claire has 3 times as many apples in her basket as Alice has in hers. (No

ElenaW [278]

Answer:

6 apples, 21 apples, 30 apples respectively

Step-by-step explanation:

Let us first start by writing expressions so that we can easily solve for the problems below.

Let us suppose Alice is x. In this case, Claire has 3 times Alice's apples, so 3x.

1. If Alice has 2 apples (x), then Claire has 3x

3*2=6 apples

Claire has 6 apples.

2. If Alice has 7 apples (x), then Claire has 3x

3*7=21 apples

Claire has 21 apples.

3. If Alice has 10 apples (x), then Claire has 3x

3*10=30 apples

Claire has 30 apples.

I hope this helps! Please let me know if you have any further questions :)

The circle given by : x^2 + y^2 - 6y - 12 = 0 can be written as:

deff fn [24]

Step-by-step explanation:

Given equation of circle is,

${x}^{2} + {y}^{2} - 6y - 12 = 0 \\ by \: compairing \: it \: with \: \\ {x}^{2} + {y}^{2} + 2gx + 2fy = 0 \: we \: get \\2 g = 0 \: or \: g = 0 \\ 2f= - 6 \\ or \: f= - 3 \\ c = - 12$

again the another form of circle is,

${x}^{2} + {(y - k)}^{2} = 21 \\ or \: {x}^{2} + {y}^{2} - 2ky + {k}^{2} - 21 = 0 \\ by \: compairing \:it \: with \: \\ {x}^{2} + {y}^{2} + 2gx + 2fy = 0 \: we \: get \\ g = 0 \\f = - k \\ c = {k}^{2} - 21$

now equating the values of f in both equations,

-k=-3

i.e. k=3

therefore k=3

Lakshmi has 11 more20-rupee notes than 10-rupee notes. If she has Rs 550 in total, how many notes of each kind does she have?

olganol [36]

Answer:

10rupee notes are 11

20rupee notes are 22

Step-by-step explanation:

Let 10-rupee note be x

20-rupee note will be x + 11

The equation will be

10x + 20(x + 11) = 550

10x + 20x + 220 = 550

30x = 330

x = 330/30 = 11 = 10rupee notes

y = 11+11 = 22 = 20rupee notes
