Answer:x=7
Step-by-step explanation:
Steps down below. Remember that angles on a straight line add up to 180 degrees
Here is the solution:
-3x-42<span> > 3
Add the numbers
-3x > 45
Divide both sides of the inequation by -3 and flip the inequality sign.
x < -15
So the answer is: </span>x < -15

Answer:
The measurement was off by 0.7%
Step-by-step explanation:
To find the relative error in the measurement, start by finding the difference.
36 - 35.75 = 0.25
Now divide that by the actual measurement of the door.
0.25/35.75 = 0.7%
Answer:
B
Step-by-step explanation:
eliminating systematic measurement errors caused by errors in the measuring instrument used to compare the quantity being measured with a standard.
The elimination method is the process of solving the system of equations, by cancelling unknowns in the system. This makes more simple to solve and easy to solve for the resting unknowns.
Equation solving. A solution is an assignment of expressions to the unknown variables that makes the equality in the equation true. In other words, a solution is an expression or a collection of expressions (one for each unknown) such that, when substituted for the unknowns, the equation becomes an identity .
