3x28=84
Step-by-step explanation:
2^4-1 so 2•2•2•2=16 and 16-1 is 15
We let x be the length (in minutes) of a certain science class. 65% of this period is spent with the experiment which lasted for about 52 minutes. Mathematically, this can be expressed as,
52 = (0.65)(x)
The value of x from the generated equation is 80. Thus, the science class is 80 minutes long.
Its 20,000. If you look of make a number line use numbers 17,242 - 20,000… <3
