Help with this algebra question
Degger [83]
We have:
 3x + 4y = 12
 The first thing we should do in this case is clear and.
 We have then:
 4y = -3x + 12
 y = (- 3x + 12) / (4)
 Rewriting:
 y = (- 3/4) x + 3
 We evaluate now for x = 4
 y = (- 3/4) (4) + 3
 y = -3 + 3
 y = 0
 The ordered pair is:
 (x, y) = (4, 0)
 Answer:
 
y = (- 3/4) x + 3
 
(x, y) = (4, 0)

Where r is the radius of the circle.

2. You know the radius of the circle B, therefore, when you susbtitute it into the formula, you obtain that the area of the circle B is:

A_B=(17ft)^{2}\pi=907.92ft^{2}

Sue has 20 biscuits in a tin There are 12 plain biscuits 5 chocolate biscuits 3 currant biscuits Sue takes at 2 random biscuits
vagabundo [1.1K]

Answer:

111 / 190

Step-by-step explanation:

Total biscuits = 20

Plain, P = 12

Chocolate, C = 5

Currant, K = 3

Assume without replacement :

Probability that biscuit are of the same type :

P(plain) :

12 / 20 * 11 / 19 = 132 / 380

P(chocolate) :

5/ 20 * 4 / 19 = 20/ 380

P(currant) :

3/20 * 2 /19 = 6 / 380

Therefore,

Probability that biscuit is of the same type :

P(plain) + P(chocolate) + P(currant)

132/380 + 20/380 + 6/380

158 / 380 = 79 / 190

Therefore, probability that biscuit aren't of the same type :

1 - P(biscuit is of same type)

1 - 79/190

(190 - 79) / 190

111 / 190
