Answer:

x=60 degrees

Step-by-step explanation:

The sum of angles in a triangle is 180 so if all angles in the triangle are equal, you just do 180 divided by 3 to get 60.

What is the point of intersection when the system of equations below is graphed on the coordinate plane?

lesantik [10]

Multiply the first equation by -2 gives:_
-2y = -8 + 2x

2y = 8 - 2x

adding these 2 equations:-

0 = 0

This shows that the 2 equations are equal so there are infinite solutions

PSYCHO15rus [73]

Answer:

A) $\dfrac{11}{23}$

B) $\dfrac{88}{345}$

Step-by-step explanation:

A survey of 46 college athletes found that

24 played volleyball,
22 played basketball.

A) If we pick one athlete survey participant at random, the probability they play basketball is

$P_1=\dfrac{22}{46}=\dfrac{11}{23}$

B) If we pick 2 athletes at random (without replacement),

the probability we get one volleyball player is $\dfrac{24}{46}=\dfrac{12}{23};$
the probability we get another basketball player is $\dfrac{22}{45}$ (only 45 athletes left).

Thus, the probability we get one volleyball player and one basketball player is

$P_2=\dfrac{12}{23}\cdot \dfrac{22}{45}=\dfrac{88}{345}$

The greater of two numbers is one less than eight times the smaller . Their sum equals 98

Kitty [74]

B>a

b=8a-1

and we are told that 98=a+b so a=98-b, using this value for a in the equation above gives you:

b=8(98-b)-1

b=784-8b-1

b=783-8b

9b=783

b=87, and since a+b=98, a=11

so a and b are 11 and 87
