Answer:
189
Step-by-step explanation:
45% x2= 90%
10% of 90= 9
90+90=180
plus that 10%
180 + 9 = 189
sorry if I'm wrong I'm trying
Answer:
9y= -9-2x
y=-(2/9)x-1
Step-by-step explanation:
Answer:

Step-by-step explanation:
To find the inverse of a function, swap the places of the x and y variables and solve for y again.

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
