Answer:

x = 40°

y = 65°

n = 65°

Step-by-step explanation:

6:

70 + 70 = 140

180 - 140 = 40

7:

55 + 60 = 115

180 - 115 = 65

8:

180 - 50 = 130

130 / 2 = 65

ss7ja [257]

Answer:

Mid point:

= ( \frac{3 +  - 5}{2} , \:  \frac{1 + 8}{2} ) \\  = ( - 1, \: 4.5)

distance:

=  \sqrt{ {( - 5 - 3)}^{2} +  {(1 - 8)}^{2}  }  \\  =  \sqrt{64 + 49}  \\  =  \sqrt{113}  \\  = 10.6 \: units

slope:

=  \frac{1 - 8}{ - 5 - 3}  \\  =  \frac{ - 7}{ - 8}  \\  =  \frac{7}{8}

Aunty Joan packs a packet of sweets to Alice and Olivia. Alice and Olivia share sweets in the ratio 7:3. Alice gives 3 sweets to
aivan3 [116]

Initially, Alice had 28 sweets and Olivia 12 sweets.

Step-by-step explanation:

First assume that Aunty Joan has x number sweets.

Alice and Olivia shared the x sweets in a ration of 7:3, this means

Alice had 7/10 x sweets and Olivia had 3/10 sweets.

Alice gives 3 sweets to Olivia, Alice will remain with ;

\frac{7}{10} x-3

Then the new ratio changes to 5:3 which means Alice will have 5/8 x number of sweets.

Equate the number of sweets for Alice in the two cases, which is

\frac{5}{8}x=\frac{7}{10} x-3\\ \\\frac{7}{10} x-\frac{5}{8} x=3\\

\frac{56x-50x}{80} =3\\\\\\\frac{6}{80} x=3\\\\\\6x=80*3\\\\\\x=240/6\\\\x=40

So there were 40 sweets at first

Using the ratio of 7:3 then

Alice had 7/10 *40 = 28 sweets

Olivia had 3/10*40= 12 sweets

Alice gave Olivia 3 sweets, so she will remain with 28-3 =25 sweets. Olivia will now have 15 sweets.The new ratio will be 25:15 simplified as 5:3.
