Hello!
Say that n is the number. There are two parts to this statement. The first part is "four less than three times a number", and the second is "is three more than two times the number. An expression fitting the first part will go on the left side of the equation, and the second part will go on the right.
Look at the first part. "Four less than three times a number". The first thing being done here is the <u>three times a number.</u> This would be 3n, as it is 3 times n. Now, there is the <u>four less</u> part. You would therefore have to subtract 4 from 3n, to get 3n - 4.
Now the second part. "Is three more than two times the number". The first thing being done here is the <u>two times the number</u>. That would be 2n. The next is "is three more than". If the other side is three more than 2n, then you must add 3 to 2n to make them equivalent. Therefore, it would be 2n + 3.
Now, set them equal to each other, and solve.
3n - 4 = 2n + 3
3n - 2n = 3 + 4
n = 7
Therefore, your number is 7.
Hope this helps!
Answer:
56.52 in
Step-by-step explanation:
- 2πr = C
- 2 × 3.14 × 9 = C
- 2 × 3.14 = 6.28
- 6.28 × 9 = 56.52 in

distance = 500 feet
Since Δ VWX and Δ YZX are similar then the ratios of corresponding sides are equal, that is
= 
= 
completing the required values gives
= 
( cross- multiply )
60l = 30 × 100 = 3000 ( divide both sides by 60 )
l = 500
distance across the swamp is 500 feet
Answer:
<u><em>x=8.5 </em></u>
Step-by-step explanation:
you have to count the numbers at the top you get 22 then you subtract 22 from 39 that will get you 17 cut 17 in half and you will get 8.5 .so put 8.5 on both of the sides on the bottom.answer <u><em>x equals 8.5</em></u>
