Answer:
whats the question?
Step-by-step explanation:
2x+5=27
subtract 5 from both sides:
2x=22
divide by 2 on both sides:
x=11
Answer and Step-by-step explanation:
Suppose x = 0.2355555... .
Multiply x by 100 and 1000:
100x = 23.5555....
1000x = 235.5555....
Let's subtract the first equation from the second:
1000x - 100x = 235.5555.... - 23.555.....
Because the decimal part for each goes on forever, we can simply cancel them out in our subtraction statement:
900x = 235 - 23 = 212
Divide both sides by 900:
x = 212/900 = 53/225
Thus, since x = 0.235555..., we know that:
0.23555.... = 53/225
Since p = 53 and q = 225 are integers, we have proven that this repeating decimal can be written as a fraction.

Answer:
210 beats
Step-by-step explanation:
28 beats per 4 seconds
28 ÷ 4 = 7
7 beats per second
7 beats · 30 seconds
= 210 beats
Answer:
2 (x^2-10)((x^2 +10)
Step-by-step explanation:
2x^4 - 200
Factor out 2
2(x^4 -100)
The inside is the difference of squares (a^2 -b^2) = (a-b)(a+b)
2 (x^2-10)((x^2 +10)
