Answer:
the answer would be 15x+ 1
Step-by-step explanation:
12a−a
=12a−1a
=12a+−1a
=a+a+a+a+a+a+a+a+a+a+a+a+−a
=a+a+a+a+a+a+a+a+a+a+a
=11a
Answer:
answer of question number 1 is 2400, 2880, 3600 respectively.
answer of question number 2 is 1384 and 1680.
Step-by-step explanation:
100×24=2400
120×24=2880
150×24=3600
692×2=1384
420×4=1680
1/3 of an unknown number is 1/3x. The word "of" lets us know to multiply. So if we add 20 to that, and it is equal to double x (that is 2x), the equation looks like this:
1. Start by multiplying everything by 3 to get rid of the fraction and get 20 + 1/3x = 2x.
2. Now subtract an x from both sides and get 60 = 5x and x = 12.
So the answer is 12
