Answer:
10 miles
Step-by-step explanation:
Given: Boat goes 
hours with 8 mph (i)
Boat goes 
hours with 12 mph (ii)
Now, lets find out distance separately to get total distance.
Formula for finding distance is
D= 
D= 
(i)
D= 
∴ D1= 6 miles (i)
D= 
(ii)
∴D2= 4 miles (ii)
To find total distance, we will add d1 and d2
Total distance = 
∴ Total distance = 
= 10 miles is the total distance covered by boat in all this time.
Step-by-step explanation:
5. Let the equation of the line be y = mx + c
m = (6-15)/(2-(-1)) = -3
sub (2, 6) and m = -3:
6 = -3(2) + c
c = 12
Equation of the line: y = -3x + 12
6. Let the equation of the line be y = mx + c
y-intercept of 7 means c = 7
y = mx + 7
x-intercept: value of x when y = 0
therefore, sub (4, 0):
0 = m(4) + 7
m = -7/4
Equation of the line: y = -7/4x + 7

Answer:
1/2
Step-by-step explanation:
Here you utilize the formula of slope which is m = y2-y1/x2 -x1
(-1,5) (1,6)
(x1, y1) ( x2, y2)
m = ( 6-5)/ (1-(-1))
= 1/(1+1)
= 1/2
Well, if he has two bags with 6 tiles each, you need to add up the number of tiles he has in total, so 6+6=12, which will be your denominator. Then to find the numerator, you have to think about how many even tiles that he has in total. 2, 4, and 6 are even numbered and he has two sets of each of those. So using that, what do you think the answer is? ^.^
Answer:
$12.75
Step-by-step explanation:
If you multiply 4.25 by 3 then you get 12.75.
