B= 3 -> 5a-30 = 54 -> 5a = 84 -> a = 16.8
-4, +1
And then the 20 letters i need to write are right here
3x + 2 = 2x + 7
Subtract 2 from both sides:
3x = 2x +5
Subtract 2x from both sides:
x = 5
Answer: x = 5
Answer:
<u>Option 1) x ≥ 0.5</u>
Step-by-step explanation:
<u>The given inequality is </u>: 2(4x - 3) ≥ -3(3x) + 5x
<u>And the options are:</u>
1) x ≥ 0.5
2) x ≥ 2
3) (–∞, 0.5]
4) (–∞, 2]
==============================
So, the solution is as following:
2(4x - 3) ≥ -3(3x) + 5x
8x - 6≥ -9x + 5x
8x + 9x - 5x ≥ 6
12 x ≥ 6
x ≥ 6/12
x ≥ 0.5
The answer is option 1) x ≥ 0.5
To work out percentage, divide what they've done (21) by the total distance (50), then multiply it by 100 to get the percentage
(21/50)*100 = 42%
