Answer:
B
Step-by-step explanation:
To find the area, multiply length by width (lw, or l×w). If the length is 10, that just leaves the width, which is unknown. We can substitute 10 for l, which leaves us with 10w.
First, you would need to determine how many questions he got correct.
30 - 12 = 18
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.

=

Now, you would cross multiply.
30x = 1,800
The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30.
x =
60Ahmad got 60% of the questions correct. I hope this helps!

Answer:
EX. 210/6
Step 1. Set up the equation, 210/6
Step 2. Divide the first digit/number 6 x 30 = 180 210 - 180 = 30
Step 3. rewrite the equation that is left, 30/6 6 x 5 = 30 30 - 30 = 0
Step 4. Only if need be for another equation, repeat step 1 and 2 until you have your answer
The Answer to the equation 210/6 is 35
Try 426/6 by yourself, please don't use a calculator.
