Answer:

x=31

y=6

Step-by-step explanation:

2x+3y=80

x+y=37

solve by elimination:( multiply second equation by 2) to eliminate x

2x+3y=80

2x+2y=74

subtract the two equations:

2x+3y-(3x+2y)=80-74

2x+3y-3x-2y=6

y=6 (3 point basket)

substitute: x+y=37, x=37-6=31

x=31 (2 point shot)

Answer:

2 point shots: 31

3 point shots: 6

Step-by-step explanation:

to get the 3 point shots:

2x+3(37-x)=80

2x+111-3x=80

x=31

31+y=37

y=6 --> 3 point shot

to get the 2 point shots:

2(37-y)+3y=80

74-2y+3y=80

y=6

x+6=37

x=31 --> 2 point shot

First you find out what 20% of 30 is (30 * 0.20 = 6)
Then you take 30/6 to get your answer (30/6 = 5)

In the circle, m arc BC = 72°. The diagram is not drawn to scale. <br><br>What is m angle BCP
QveST [7]

Answer:

Measure of ∠BCP is 36°

Step-by-step explanation:

Given the circle in which measure of arc BC is 72°

we have to find the measure of angle BCP.

m∠BOC=∠2=72°

By theorem angle subtended at the centre is twice the angle formed at the circumference of circle.

∴ ∠2=2∠1 ⇒ 72=2∠1

⇒    ∠1=36°

By alternate segment theorem which states that

The angle formed between a chord and a tangent through one of the end points of chord is equals to angle in alternate segment.

⇒ ∠3=∠1=36°

Hence, measure of ∠BCP is 36°

Option D is correct

Anon25 [30]

Answer:

8=41

7=49

10=41

9=49

Step-by-step explanation:

angle 8 is given and since 7 and 8 make 90 then 7 =49 because 90-41=49. 10 and 8 are the same size (at least it looks like it) therefore 7 and 9 are the same too. So that is how I got the answers.
