Team infinite dimensions canoed 15 3/4 miles in 3 hours. what was their average rate of speed in miles per hour?
Karo-lina-s [1.5K]
Miles per hour

(15 and 3/4) miles per 3 hours

remember that
(a+b)/c=(a/c)+(b/c)
and
a and c/d=a+c/d

so

(15 and 3/4)/3=(15/3)+(3/4)/3
remember that dividing by a number is like multiplying by a fraction
15/3=5
(3/4)/3=(3/4) times (1/3)=3/12=1/4

(15/3)+(3/4)/3=5+1/4=5 and 1/4

answer is 5 and 1/4 miles per hour

4 cookies = 4*10 = 40g fat

Which ordered pair is the solution to the system of linear equations y = -7x + 2 and y = 9x - 14?
lisabon 2012 [21]
Y = -7x + 2
y = 9x - 14

-7x + 2 = 9x - 14
14 + 2 = 9x + 7x
16 = 16x
1 = x

y = -7x + 2
y = -7(1) + 2
y = -7 + 2
y = -5

solution is : (1,-5) <==
