Answer:
S=4
Step-by-step explanation:
Intercept at, y=0 and at x=0
-3(0)+5(y)=60
y=12 , z= 30, (y intercept) or (0,12,30)
-3(x)+5(0)=60
x=-20,z=30, (x intercept) or (-20, 0, 60)
9/6 = 1 3/6
⇒ which equal 1 1/2
Answer:
Step-by-step explanation:
Given
sunny day speed= s mph
Rainy day speed=s+1 mph
Derek average speed =2.8 miles/hr
s<2.8<s+1
so on sunny day speed must be 2 mph
and on rainy day speed must be 3 mph

Let x be the distance traveled in sunny and y be the distance traveled in rainy weather

Let 


Fraction of distance traveled on sunny weather

The rectangle they give you is 12 units tall. This is the result of scaling by a factor of 1.5, ie it is 1.5 times taller than what the answer will be. Let the answer rectangle have a height of h. This means h*1.5 = 12, or 1.5h = 12
Divide both sides by 1.5 to find that h = 8. The answer rectangle's height is 8 units.
The width's will be treated in a similar manner. I picked on the height since it's easier to see that the height lines up with 12 (the width seems to be between 2 and 4, but its not clear if its at the midpoint).
