Answer and explanation:
Since x = number of true or false questions correct
And y = number of multiple choice questions correct
And each question for x =2 points
each question for y=3 points
since she then needs a total score of more than 93 to pass, we add up total correct questions and
Inequality equation = 2x +3y >93
Answer:
- 40
Step-by-step explanation:
When a = 4, and x = -4:
Evaluating algebraic expressions simply involve substituting the given values for <em>a</em> and<em> x</em> into the expression, -9a + x.
Hence, -9a + x = -9(4) + (-4) = -36 - 4 = -40
Therefore, the correct answer is -40.
Answer:
Equation: 12 + 3x = 30
Solution: x = 6
Step-by-step explanation:
12 + 3x = 30
X stands for how many hours she rented it for. You want to solve for x, so get x by itself.
12 + 3x = 30
-12 -12
---------------------
3x = 18
Divide both sides by 3
3/3x = 18/3
x = 6
