A triangle always adds up to 180 degrees:
Therefore, 48 + 6x + 9x-3 = 180
Solve for x:
180 - 45 = 15x
135 = 15x
x = 9 degrees
$2.50
Step-by-step explanation:
10 dimes are 100 aka 1 dollar, and 30 nickels make 250
Ten percent of 640 is 64.
640/100=6.4
6.4*10=64.
There are many other ways to find this but that is the way I have always used :)
Hope this helps!
The formula for this is
worker 1 * worker 2 / worker 1 + worker 2
7 * 4 / 7 + 4 =
28 / 11 =
2.54 hours
