Ok, for this one...  see the picture

Step 1:  Find angle R by adding angle Q and P then subtract from 180 (all angles add to 180).  That gives us R angle of 70 degrees.

Step 2:  Find angle QRX by subtracting angle R from 180 (the 2 angles that make up the straight line will add to 180).  180 - 70 = 110 degrees.

Step 3:  Find y by setting the equation to the answer we found in step 2.
y + 25 = 110
y = 85 degrees

Check out the picture.  It should help.

What is the unit rate of y = 2/3x ? ( must satisfy the definition of unit rate )
Nat2105 [25]
The unit rate is 2/3 because in the line y=2/3x, 2/3 is the slope (y=mx+b). The slope of the line is pretty much the definition of a unit rate because the unit rate is a constant addition or subtraction over and over. In addition, it is a straight line(y=mx+b) and the values are going up at a constant rate of 2/3.

Help!!! Quick!!! Plzzzzz!!!

Answer:

x = -8

y = 9

Step-by-step explanation:

to solve this expression using simultaneous equation, we would say let

y =9............................................. equation 1

 6x + 5y =-3............................................equation 2

substitute equation 1 into equation 2

-3 = 6x + 5y............................................equation 2

6x + 5(9) = -3

6x + 45 = -3

collect the like terms

6x = -3-45

6x = -48

divide both sides by the coefficient of x which is 6

6x/6 = -48/6

x = -8

therefore y = 9

x = -8
