Answer:
25%
Step-by-step explanation:
percent error is found by the equation(measured-real)/real x 100
20 is the measured value and 16 is the real value
(20-16)/16 x 100
4/16 x 100
0.25 x 100
25
hope this helps!
Step 1: Rewrite the equation
-14+6b+7-2B=1+5b
Step 2: Combine like terms
-14+6b+7-2b=1+5b
-7+4b=1+5b
Step 3: To isolate b, first add 7 on both sides
-7+4b=1+5b
+7 +7
_________
4b=8+5b
Step 4: Again, trying to isolate b, subtract 5b on both sides
4b=8+5b
-5b -5b
_______
-b=8
Step 5 (final step): Because the variable cannot be negative for a final answer, multiply each number by -1.
-1(-b=8)
b= -8
Final Answer: b=-8

Answer: Interior Angle
Step-by-step explanation:
The angle BAD is fully enclosed, it is on the inside
Answer:
Option D (4, -5)
Step-by-step explanation:
This question can be solved by various methods. I will be using the hit and trial method. I will plug in all the options in the both the given equations and see if they balance simultaneously.
Checking Option 1 by plugging (-4, -5) in the first equation:
-2(-4) + 6(-5) = -38 implies 8 - 30 = -38 (not true).
Checking Option 2 by plugging (-5, 4) in the first equation:
-2(-5) + 6(4) = -38 implies 10 + 24 = -38 (not true).
Checking Option 3 by plugging (1, -6) in the second equation:
3(1) - 4(-6) = 32 implies 3 + 24 = 32 (not true).
Since all the options except Option 4 have been ruled out, therefore, (4,-5) is the correct answer!!!
Answer:
In mathematical statements, it can be expressed as y = kx. This reads as “y varies directly as x” or “y is directly proportional as x” where k is constant in the equation. Example: y is directly proportional to x, when x = 15, y = 30.
