Answer:90%
Step-by-step explanation: we know this because the total about of questions on the test is 20 and for the score to add up to 100% each question has to be worth 5% so we can just do 5 x 18 to get 90%. or (5 x 2) - 100 to also get 90%
Answer: 19x
Step-by-step explanation:Because if you add 22 and 2 and minus 3 and add the x you get your answer 19x
The equation has to (or be transformed to) contain one object in the left side and the other object at the right side multiplied by a constant, without an independent term.
The value of <em>x </em>in the equation, (3x + 30), is 10.
