Answer: b = 69

The slashes mean the opposite angles are the same. This is and isosceles triangle, which mean two sides are the same and one is not.

A triangle = 180

We know one angle is 42 and the other two angles are the same.

Subtract 42 from 180

180 - 42 = 138

Now the 138 is going to two sides but we know they are equal so we can divide 138 by 2

138 divided by 2 = 69

So b = 69

The cost of 1 purse and 1 watch is £27.
EastWind [94]
1 purse and 1 watch is 27€
2 purse and 1 watch is 41€

So we can see the watch is constant means 1 watch is every time but purse is increase by 1 in the next expression

So 41-27 = 14€ is one purse
because the watch is every time one, so the next value increase is by purse

1purse and 1watch = 27
We know,
1 purse is 14€
So 27-14=13€ is one watch

We can check by
1 purse is 14 so two purse is 14*2=28
28+13=41
Which is same as they said in second expression

Hope it help you!¡

A line has a slope of -5/3. Through which two points could this line pass?
ladessa [460]
If there is no other context, you could use the points (0,0) and (3,-5) because you move down 5 and to the right 3.

Kala purchased a prepaid phone card for $30. Long distance calls cost 9 cents a minute using this card. Kala used her card only
Romashka [77]

Answer:

The call lasted 13 minutes

Step-by-step explanation:

In this question, we are told to find the number of minutes a call lasted.

The initial amount on the card is $30 and after making a phone call just once, the balance went down to $28.83

What was used would be 30 - 28.83 = $1.17 or simply 117 cents

Now these long calls come at a cost of 9 cents per minute and we have a total of 117 cents here; the number of minutes is thus 117/9 = 13

This means Kala spent 13 minutes on the call
