Donovan earned 99 points on his
science project. if his grade was 90%, how many points were possible?

110 = points possible

Step-by-step explanation:

The points received equals the points possible times the percent

99 = points possible * 90%

Changing this to decimal form

99 = points possible * .90

Divide each side by .90

99/.90 = points possible *.90/.90

110 = points possible

b if for most of the graph

d if y intercept

step-by-step explanation:

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
