Answer:
The distance of the rivers on the map is of 1.23 inches.
Step-by-step explanation:
We use proportions to solve this question, by a rule of three.
We have that:
If the actual distance is of 1000 miles, the distance on the map is of 12.3 inches. If the actual distance is 100 miles, what will be the distance on the map?
1000 miles - 12.3 inches
100 miles - x
Applying cross multiplication
The distance of the rivers on the map is of 1.23 inches.
Step-by-step explanation:
y = 5x - 4
When x = 0, y = 5(0) - 4 = -4.
When x = 1, y = 5(1) - 4 = 1.
When x = 2, y = 5(2) - 4 = 6.
The 3 ordered pairs we have are (0,-4), (1,1) and (2,6).
We now check the point (-5,-29):
(-29) : 5(-5) - 4
-29 : -25 - 4
-29 : -29 => -29 = -29.
Since Left hand side = Right hand side, the point (-5,-29) is a solution.
Since 11 out of 55 specials were salmon filet,
The percentage of specials that were salmon filet is 11/55 = 20/100 = 20%.
Answer:
72 + 8x
you would multiply 8 by 9 + x
0.12 = 12/100 = 6/50 =3/25
0.12 =3/25
