the first few bars are the people who walked fewer than 4,000, so add up the numbers on the side (2 and 5) and you get 7, so a
F = d + e + t Flip the sides to put t on the left
d + e + t = F Subtract d from both sides
e + t = F - d Subtract e from both sides
t = F - d - e
Answer:
x = 1/10
Step-by-step explanation:
2/x -2 = 3/2x +3
Add 2 to each side
2/x -2+2 = 3/2x +3+2
2/x = 3 /2x +5
Subtract 3/2x from each side
2/x -3/2x = 3 /2x - 3/2x +5
2/x - 3/2x = 5
Get a common denominator
2/x *2/2 -3/2x =5
4/2x - 3/2x = 5
1/2x =5
Multiply each side by 2x
1 /2x * 2x = 5 *2x
1 = 10x
Divide each side by 10
1/10 = 10x/10
1/10 =x
