It's really simple actually, but sorry I can't come up with an equation. You can just add or multiply students per bus and students per car until you get to 195. Each bus can hold 45 students, so 45 x 4 = 180. Each car can hold 5 students, so 5 x 3 = 15. In total, 15 + 180 = 195 students.

Answer:

x = -3

Step-by-step explanation:

System of equations has been given as,

y = 2x + 8

y = [tex]-\frac{2}{3}x[/tex]

Since, solution of the system of equations is the point of intersection on the graph.

Therefore, point of intersection or solution of the system will be,

(x, y) = (-3, 2)

This common point will satisfy both the equations.

And x = -3 will also both the equations.

Answers

Answer:

y=24; Angle 1: 61 degrees; Angle 2: 58 degrees; Angle 3: 61 degrees

Step-by-step explanation:

-11+3y+34+y+37+y=180 The sum of all the angles in a triangle is 180 degrees.

60+5y=180 Combine like terms

5y=120 Subtract 60 from 180

y=24 Divide 120/5

Angle 1: -11+ 3(24)= 61 degrees

Angle 2: 34+24=58 degrees

Angle 3: 37 + 24= 61 degrees

Answer:

The measure of angle two is 47 degrees (first triangle), and the measure of angle four is 42 degrees (second angle)

Step-by-step explanation:

Remember that all triangles have a full measurement of 180 degees.

Since measure one is is 65 degrees, we need to add 65 and 68, which is 133 degrees.

Now we subtract 180 - 133 = 47.

The measure of angle two is 47 degrees.

Since the angle of measure three is 89 degrees, we need to add 89 + 49, which is 138 degrees.

180 - 138 = 42.

Your answer must be in the form of a fraction.

Answers

x = 2/5

good luck

You need to get x by itself to solve

So to get rid of 5/2, you need to multiply both sides by the reciprocal or 2/5...

5/2*2/5 = 1 which we don't write and 1*2/5 = 2/5

So now you'd have x =2/5
