We have to find 100% of the number. We can use proportion to get it 3% -----------1.5m 100% -------- x crossmultiply now 3*x=1.5*100 3x=150 /:3 divide both sides by 3 x=50m
2. Similar situation 40% ------------1000 100% -----------x crossmultiply 40*x=100*1000 40x=100000 /:40 x=2500 - its the answer
The value of x is in the solution set of 3(x – 4) ≥ 5x + 2 is -10
<u>Solution:</u>
Need to determine which value of x from given option is solution set of 3(x – 4) ≥ 5x + 2
Lets first solve 3(x – 4) ≥ 5x + 2
3(x – 4) ≥ 5x + 2
=> 3x – 12 ≥ 5x + 2
=> 3x – 5x ≥ 12 + 2
=> -2x ≥ 14
=> -x ≥ 7
=> x ≤ -7
All the values of x which are less than or equal to -7 is solution set of 3(x – 4) ≥ 5x + 2. From given option there is only one value that is -10 which is less than -7
Hence from given option -10 is solution set of 3(x – 4) ≥ 5x + 2.
