Answer:
a = 0.3
b = 0.4
c = 40%
d = 15%
Step-by-step explanation:
There are a total of 10 tick marks. So we know that 1 tick mark = 10%
a has 3 tick marks so you can say it's 0.3
b has 4 tick marks so you can say it's 0.4
c also has 4 tick marks, but it's asking for the percentage, so you get 40%
d is 1 1/2 tick marks. It's also asking for percentage. You know 1 tick = 10% and 1/2 tick = 5* so d = 15%

Answer:
x = 13/3
Step-by-step explanation:
4(8x-3) - 30x = 5(x-5)
Distribute
32x - 12 - 30x = 5x -25
Combine like terms
2x -12 = 5x-25
Subtract 2x from each side
2x-12-2x = 5x-2x -25
-12 = 3x-25
Add 25 to each side
-12+25 = 3x-25+25
13 = 3x
Divide each side by 3
13/3 = x
