3. From birth, a normal person blinks an average of 25 times a minute when awake. When Katelyn was 10 years old, she blinked an average of 27 times per minute. When she was 11, she blinked 26 times per
minute. When she was 12, she blinked 25 times per minute. At 10 years old, Katelyn averaged 9 hours,
45 minutes of sleep each day; at age 11, she slept 9 hours, 30 minutes; at age 12, she slept 9 hours, 15
minutes. What is the sum of the number of times Katelyn blinked when she was 10, 11, and 12 years
old? (Use 365 days in a year).

the answer for this question is 38

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
