130 + 2x = 180
2x = 180 - 130
2x = 50
x = 50/2
x = 25
2x + 4y + 54 = 180
2(25) + 4y + 54 = 180
50 + 4y + 54 = 180
4y + 104 = 180
4y = 180 - 104
4y = 76
y = 76/4
y = 19
answer: x = 25 and y = 19
Answer:
16 managers
Step-by-step explanation:
Here, we want to calculate the numbered managers at the park
From the question, 4% of the 400 are managers
Thus;
4/100 * 400 are managers
= 1600/100 = 16
So if 1/2 inches = 16 miles then 1 inch = 32 mi
now we can divide 88 by 32 to find how far apart they are in inches on the map
88 / 32 = 2.75 inches
