1/2x - 6 = 88....where x = the original price
1/2x = 88 + 6
1/2x = 94
x = 94 * 2/1
x = 188 <==
Answer:
Step-by-step explanation:
1 and 3 are 128
4 is 52
2 and 6 are 136
5 is 44
7 and 10 are 74
9 and 8 is 106
13 and 18 equals 52
14 and 17 is 128
12 and 15 is 44
11 and 16 is 136.
Answer:
17.8
Step-by-step explanation:
First, round the two. umbers to the nearest the th, or the first number past the decimal. 19.28 rounds to 19.3 (round up because 8 is bigger than 5) and 1.546 rounds to 1.5 (round down because 4 is smaller than 5). Then subtract. 19.3 - 1.5 = 17.8
Here's one way to convert the number to the ratio of integers.
- Count the number of repeating digits. Call this number <em>n</em>. Here, only 5 has an overline, so there is only one repeating digit. That is, <em>n </em>= 1.
- Multiply the number by 10^(-n) and subtract that from the original number. Call the result <em>p</em>. Here, doing this gives

- Compute the value <em>q</em> = 1 - 10^(-n). The result of step 2 is <em>q</em> times the original number. Here, <em>q</em> = 1 - 10^-1 = 0.9.
- Create the fraction <em>p/q</em>. Note that both <em>p</em> and <em>q</em> have a finite number of decimal digits, so this is easily converted to the ratio of integers, by moving the decimal point an equal number of places in the numerator and denominator. Reduce the resulting fraction as may be required. This is the fraction you're looking for. Here, p/q = 3.23/0.9 = 323/90. No reduction of this fraction is possible.
The fraction you're looking for is ...

3x-3*4=-15
3x-12=-15
3x=-15+12
3x=-3
x=-3/3
x=-1
