Answer:
Step-by-step explanation:
7x + 11 = 74
7x = 63
x = 9
answer is B
We can solve for both x and y of System A and B to compare the values of x.
System A. Multiply by 4 the first equation and add both equations,
12x + 8y = 12
+ -2x - 8y = -1
We will be left with equation,
10x = 11
The value of x is 11/10
System B. Multiply the first equation by -2 and add the equations,
2x + 28y = -2
+ -2x - 8y = -1
We will be left with 20y = -3. Substitute the value of y to any of the equations. This gives a value of x equal to 11/10.
The answer therefore is that both systems will have the same value of x's.
Hence , smallest solution is -6

Answer:
a= 140 b=140 c= 40 d= 140
Step-by-step explanation:
a b and d are congruent to the given angle and d is supplimentary to c so 140 +40 = 180
