250(x) - 150(15-x) = 2150
250x - 2250 + 150x
400x - 2250 = 2150
400x = 4400
x = 11
11 were correct
To estimate the difference, you find the difference first. To find the difference, you subtract the numbers you are given. Then you estimate your final answer (the difference).
Yes.
Make the denominators the same using equivalent fractionsAdd or subtract the numerators.Change the result to a mixed fraction if the numerator is larger thanthe denominator.Simplify the final result if possible.
You can't. For example if your equation is: 2x+7=12 then you will subtract 7 by itself, then subtract 7 from 12. You then get 2x=5. You will then divide 5 by 2 and you will get x=2.5 as your final answer.
It will depend on how accurate the final answer is. More questions will provide a more accurat answer.
yes ,each word must be spelled correct even if said incorrect
Dr. Smith's chemistry midterm has 60 questions. She scores the test as follows: for each correct answer, she gives 2 points; for each incorrect answer, she subtracts 2/3 of a point; for unanswered questions, she neither gives nor subtracts points. If Andrew scored a 68 and did not answer 2 of the questions, how many questions did he answer correctly?
You can subtract 679.
When calculating acceleration to find the change in velocity, you subtract the initial velocity from the final velocity. The formula for acceleration is: acceleration = (final velocity - initial velocity) / time.
To find acceleration, you subtract the initial velocity from the final velocity and then divide by the time taken to achieve the change in velocity. The formula for acceleration is (final velocity - initial velocity) / time.
Subtract the initial from the final
There are 50 questions in ccna1 final exam.
Incorrect sketching could result an incorrect final product.
"il s'appelle" (without the final 's') means 'he is called ... / he is named..)
If there are 40 questions - each question is worth 2.5 % of your final mark. Therefore 28 correct answers will give you a 70% pass.
The final answer is -10,862.
