A.
x= # of miles per inch on the map
4 1/2 x inches on the map = 24 miles in real life
2(4 1/2 x) = 2(24) Addition Property of Equality
9x = 48
9x/9 = 48/9 Division Property of Equality
x = 45/9 + 3/9
x = 5 + 1/3
x = 5 1/3
1 inch to 5 1/3 mi
b.
1/4 in = 1 mi
z= 1 mi
z= 1/4 in
24z
24(1/4)
6 in
Answer: 1,817 minor earthquakes
Step-by-step explanation: First you make 89.1% and change it to a decimal. You do that by moving the decimal point over 2 spaces to the left. Next you take 16,674 and divide it by 0.891. Once you get that number you subtract 16,674 by your new number from when you divided to get your answer.
-2-3x=3+1x
-2-3=1x+3x
-5=4x
x=-1.25
380 / 16 = x / 6
16x = 2,280
x = 142.5
Answer is C!
Answer:
A. y = -3/2x + 1
B. y = -5/3x + 10
C. y = -x + 6/5
Step-by-step explanation:
A. You just have to isolate the y so divide by 4: y = -3/2x + 1
B. 3y = -5x + 30
Divide by 3: y = -5/3x + 10
C. -5x + 6 = 5y
Divide by 5: -1x + 6/5 = y OR y = -x + 6/5
