Let the required number is 2x ,
According to the condition,
➡ 10 times the sum of half of 2x and 6 = 8
Therefore the value of x is -5.2
And, required number is -5.2
Answer:
42
Step-by-step explanation:
The measure of angle K is 48, the measure of angle m is 90. From there you have 138 degrees. A triangle is 180 degrees. You subtract 138 from 180.
<span>3x + 8x + 4x = 6x + 63
15x = 6x + 63
9x = 63
x = 7
so
5x+ 23 =5(7) + 23 = 35+23 = 58</span>
The correct answer would be more than 2,000 (approximately 2,205) because on the first he did 30, the second was 33, third was 36, and so on. You would have to make a chart for this, which could be somewhat boring, or you could write it out and do 30+30+3+30+6+30+9, etc for 30 different days, with 30 being for each day and progressively adding 3. Hope this helped!
