Step-by-step explanation:
When x represents the number, "the sum of 3 and a number" is (x+3). Twice that sum is 2(x+3). "Is 30" means this expression is equal to 30:
2(x +3) = 30 . . . . an equation for the given conditions
__
We can solve this equation by dividing by 2:
x + 3 = 15
x = 12 . . . . . . subtract 3
The number is 12.

Step-by-step explanation:
90-29=61
sin(61)=0.87461...
sin(61)=x/500
sin(61)*500 = x
Move the decimal point to the right two place values, and set the number over 100
0.95 = 95/100
95/100 is your fraction answer.
Simplify it if asked. 95/100 = 19/20
