Answer:

8. (A) x = 8 , 10. (C.) x = 3

Step-by-step explanation:

Number 8 you could do 75 - 35 = 40

so what can you multiply 5 by (x) to get 40? you would multiply 5 by 8 or (x) and get 40

then add 35 + 40 to get 75 degrees which is the parallel angle to the other 75 degrees.

Number 10 you just want to get them to the same number.

so you would do ( 97 - 3 ) to get the ANSWER 87.

so x = 3

What does the pair of equations y = 5, z = 6 represent? In other words, describe the set of points (x, y, z) such that y = 5 and

stiks02 [169]

Answer:

Option b.

Step-by-step explanation:

The set of points (x, y, z) such that y = 5 and z = 6.

So, all pairs are in the form of (x,5,6).

where, x can be any real number.

It the set of points (x,y,6), y and z-coordinates are constant.

So, the pair of equations y = 5, z = 6 represents a line parallel to x-axis and the distance of this line from xy-plane is 6 units and from xz plane is 5 units.

Therefore, the correct option is b.

Jon had 45 dollars in his account. He made 7 dollars

creativ13 [48]

First, 150-45 because we already know he had 45 dollars so we are left with 105$ so next you do 105$ divided by 7$ which gives you 15 hours. The answer is 15 hrs :)
