Well 500 mm = 50 cm so if you add both segments together you will get a 50+30=80cm segment
Answer:
B
Step-by-step explanation:
You have to evaluate the power and calculate the sum or difference in order to get the answer
Answer:
No solution
Step-by-step explanation:
y=x-1 and y-x=-9
1st make sure both equations are in slope intercept form
since the 2nd equation isn't, you change it by adding x to both sides and rewrite it as y=mx+b so
y-x=-9
+× +×
y=×-9
now you have y=x-1 and y=x-9
substitute the y with the other equation
x-1=x-9
subtract x from both sides since you can't have the variable on both sides
now you've got -1 = -9
and since that equation isn't true, it has no solution.
