Answer:

The exterior angles need to equal 360 degrees.

You have 70 + 65 + 75 = 210

So 2x + 3x need to equal 360 - 210 = 150

5x = 150

x = 150 /5 = 30

2x = 2 *30 = 60

3x = x *30 = 90

An interior angle and an exterior angle need to equal 180 degrees.

The largest interior angle would need to correspond with the smallest exterior angle.

The smallest exterior angle is 2x which equals 60 degrees.

The largest interior angle would be 180 - 60 = 120 degrees.

mixer [17]

Answer:

2162.2 degrees Celsius

Step-by-step explanation:

Celsius (°C) = (Fahrenheit - 32) / 1.8

3924-32 = 3892

3982 / 1.8 = 2162.2222222222222222222222

Lina20 [59]

Answer : Z = 5

Step-by-step explanation :

62 = 9z + 17

-17 -17

45 = 9z

/9 /9

5 = z

Plug it back in :

62 = 9(5) + 17

62 = 45 + 17

62 = 62

Which is the approximate solution to the system y = 0.5x + 3.5 and y = −A system of equations. y equals 0.5 x plus 3.5. y equals
Elena L [17]

Answer:

The approximate solution of the system of equations is the point (-2.7,2.1)

Step-by-step explanation:

we have

y=0.5x+3.5 -----> equation A

y=-\frac{2}{3}x+\frac{1}{3} -----> equation B

Solve the system by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (-2.714,2.143)

see the attached figure

therefore

The approximate solution of the system of equations is the point (-2.7,2.1)

vagabundo [1.1K]

Answer:

1 1/6

Step-by-step explanation:

2 2/3 = 2+2/3

1 1/2 = 1+1/2

So (2 2/3) - (1 1/2)=2+2/3-(1+1/2)=

2+2/3-1-1/2=1+(2/3-1/2)=1+(4-3)/6=1+1/6=
