Answer: 15
Step-by-step explanation: To evaluate an expression, we plug the value of the variable into the expression and simplify.
Since we have 7 - 2x and x is -4, we have 7 - 2(-4).
Simplifying from here, 2(-4) is -8 so we have 7 - (-8).
Now, remember that a a minus sign followed by a
negative sign turns the two signs into a plus sign.
So 7 - (-8) can be thought of as 7 + (+8) which is 15.
Answer:
John Roberts must serve a minimum of 12, 543 days to surpass John Mrshall's record of justice.
Step-by-step explanation:
John Marshall = 2079 + 10, 463 = 12, 542 days
Now, we have to add 1 more day to pass John Marshall because if we do not, we would only be on the same level as John Marshall and NOT EXCEEDING him.
Answer:
1025
Step-by-step explanation:
3075/3=1025
18 - (8 - 3 • (2t + 5)) = 0
6t + 25 = 0
3.1 Solve : 6t+25 = 0
Subtract 25 from both sides of the equation :
6t = -25
Divide both sides of the equation by 6:
t = -25/6 = -4.167
Final answer is
t = -25/6 = -4.167
That's an awfully broad question. Could you not be more specific?
A basic example: Suppose you are told that sin theta = 1/2. Solving this equation would require finding the measure of the angle theta. In this case the answer would be "30 degrees," or "pi/6 radians."
