Answer: Scale factor of -1/2
Step-by-step explanation:
B=A*(-2)
A=B/(-2)
A=-(B/2)
A=B*(-1/2)
Scale factor of -1/2
30% of 90 <em>whenever it says "of" put in a multiplication sign </em>
30% x 90 <em> take out the % sign (percent means divided by 100)</em>
30/100 =3/10 <em>simplify,then multiply by 90</em>
3/10 x 90 = 270/10 <em> simplify</em>
270 = 27
90 - 27 = 63 <em>subtract 27 because it is the amount read so far from the total</em>
Keisha has to read 63 more minutes to reach her goal.
