The average is (time)/(number of problems)=(45/60)/20=(3/4)/20=3/80 hours per problem. In minutes, the answer would be 3/80*60=9/4 minutes per problem.

Answer:
Step-by-step explanation:
y/2 - 4 = x/3 can also be written as 1/2y - 4 = 1/3x
slope intercept form is y = mx + b
1/2y - 4 = 1/3x....multiply entire equation by 6, to get rid of fractions
3y - 24 = 2x ...add 24 to both sides
3y = 2x + 24....divide both sides by 3
y = 2/3x + 6 <===
Answer:
The picture that does not contain enough information to prove that ΔABC = ΔDEF is
(3) Picture (3)
Step-by-step explanation:
The given information in picture (3) is the Angle-Side-Side of ΔABC corresponds with the Angle-Side-Side of ΔDEF,
However, the condition of Angle-Side-Side of ΔABC, is not sufficient to prove that ΔABC is congruent to ΔDEF congruency because the length of the unknown side can have two possible values
