Answer:

mAOB = 139 degrees

Step-by-step explanation:

1) By supplementary angles, you can set up the equation:

mAOB + mBOC = mAOC = 180

8x + 51  + (6x - 25) = 180

2) Solve for x:

14x + 26 = 180

14x = 154

x = 11

3) Substitute x into 8x + 51 to get mAOB:

8(11) + 51

=88 + 51

=139

A rectangular prism with a volume of 3 cubic units is filled with cubes with side lengths of 1/4 unit how many 1/4 unit cubes do
Julli [10]

Answer:

192 cubes

Step-by-step explanation:

So all we need to do is:

1) Find the area of 1 cube.

2) Divide the large prism volume with this.

SO 1)

the volume of cube = Length * width * height = (1/4)^3 = 1/64

SO 2)

the volume of prism / the volume of cube = 3/(1/64) = 192

Answer: 192 cubes

Hayley so 20 tickets to the school play for total of $225. Early bird tickets were $10 regular priced tickets are $15. Wright an
alexandr402 [8]

System of Equations

For the problem to solve we'll use the following variables:

x = number of the early bird tickets sold

y = number of the regular tickets sold

Haley sold a total of 20 tickets, thus:

x + y = 20 [1]

Early bird tickets cost $10 and regular tickets cost $15, thus the total money collected is:

10x + 15y = 225

Dividing by 5:

2x + 3y = 45 [2]

We have to solve the system of equations [1] and [2].

Multiply [1] by -2:

-2x - 2y = -40 [3]

Add [3] to [2]:

-2x - 2y +2x + 3y = -40 + 45

Simplifying:

y = 5

Substituting in [1]:

x + 5 = 20

Subtracting 5:

x = 20 - 5

x = 15

Solution: Hayley sold 15 early bird tickets and 5 regular-priced tickets

The order pair solution is (15,5)
