Answer:
He needs 4 more pieces
Step-by-step explanation:
Here, we want to know the number of more string pieces that are needed
Firstly, we need to the number of string pieces obtained from the 8 2/5 inch piece
we divide 8 2/5 by 3/5
That will be;
42/5 * 5/3 = 14
So what he will get is 14 pieces from the 8 2/5 inch
The number of pieces needed is thus;
18-14 = 4
The answer would be less than due to the decimal placing so this
A + b +c = 75; where a is the greatest number; b is the middle number; c is the least number;
a = 2 * c;
b = 3 + c;
then, 2 * c + 3 + c + c = 75 => 4 * c = 72 => c = 72 / 4 => c = 18 => a = 2 * 18 => a = 36; b = 3 + 18 => b = 21;
Answer:

400 - 100 is 300. Hope this helps, please tell me if i am wrong
Answer:
a> -32
Step-by-step explanation:
-40 < 2(a +12)
-40 < 2(a) +2(12) <em>(</em><em>expand</em><em>)</em>
-40 < 2a +24
-40 -24 < 2a <em>(</em><em>bring</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>one</em><em> </em><em>side</em><em>)</em>
-64 < 2a <em>(</em><em>simplify</em><em>)</em>
2a > -64
a > -64 ÷2
a > -32
