Answer:
14
Step-by-step explanation:
7*2y+27
14y+27
14 is coefficient of variable y
Answer:
y = -1
x = 9
(9, -1)
Step-by-step explanation:
1) Since "x" equals <em>-4y+5, </em>substitute that into the bottom equation for x: -4y+5+2y=7
2) Combine like terms: -2y+5=7
3) Subtract 5 from both sides: -2y=-2
4) Divide both sides by -2: y=-1
Now you have figured out that <em>y= -1 </em>
1) Substitute <em>-1 </em>for <em>y </em>in the top equation: x=-4(-1)+5
2) Solve: x=4+5
3) x=9
Now you have figured out that <em>x=9 </em>

The final answer is (9, -1)

The answer is (A) SSS. The triangles share one side and it is indicated that the other two are congruent.
Answer:
ABQ = 139
BCR is the same as QBC since they are alternate interior angles
BCR = 41
Step-by-step explanation:
CBQ and SCB are same side interior angles so they add to 180
2a-9 + 5a +14 = 180
Combine like terms
7a +5 = 180
Subtract 5 from each side
7a = 175
Divide by 7
7a/7 = 175/7
a = 25
ABQ is the same as SCB since they are corresponding angles so
ABQ = SCB = 5a+14 = 5*25+14 = 125+14 = 139
BCR is the same as QBC since they are alternate interior angles
BCR = QBC = 2a-9 = 2*25 -9 = 50-9 = 41
