q= 6
r= 7
work--
Multiply 1st column by -2:
-30q+8r=-124
5q+8r=86
Subtract 2nd column from the first column:
-35q= -210
Solve for q:
q=6
Subtract q=6 by any of the two equations, so:
-30q+8r=-124
-30*6+8r=-124
Solve for r:
r=7
Answer:
Step-by-step explanation:
by the property of corresponding angles (2x +16) and (3x-12) will be equal
working uot from the equation 3x-12 = 2x+16 we get x=28
and we know that 3x-12 and y are supplementry as they form a linear pair
from that we will get the equation - 3x-12 + y = 180 and we know the value of x sowe will get y as 108
I believe the statement that is always true is
A. Vertical angles are congruent
Answer:
Step-by-step explanation A line of best fit is often useful to attempt to represent data with the equation of a straight line in order to predict values that may not be displayed on the plot.n:
Answer:
11. ∠B ∠ABC ∠CBA ∠2
17. QR = 12
Step-by-step explanation:
11. ∠B ∠ABC ∠CBA ∠2
17. Given: PS = 18 PR = 15 PQ ≅ RS
It would be good if you could draw a picture for yourself
So, RS = PS - PR
= 18 - 15 = 3
RS = PQ = 3
QR = PS - RS - PQ
= 18 - 3 - 3
= 12
