Având în vedere expresiile 4a + 7b + 6c și ecuațiile date a + b = 16 și b + 2c = 28.
4a + 7b + 6c pot fi scrise ca
<em>a + a + a + a + b + b + b + b + b + b + b + c + c + c + c + c.</em>
<em>= (a + b) + (a + b) + (a + b) + (a + b) + (b + 2c) + (b + 2c) + (b + 2c).</em>
Înlocuind valorile a + b = 16 și b + 2c = 28, ajungem
(a + b) + (b + 2c) + (b + 2c) + (b + 2c)
= 16 + 16 + 16 + 16 + 28 + 28 + 28
= 64 + 84
= 148.
<h3>
Prin urmare, 4a + 7b + 6c = = 148.</h3>

Step-by-step explanation:
9 pieces 18 divided by 1 7/8 = 9.6 but you can’t have .6 so it’s just 9
Answer:
Range A = 386ft
Range B = 427ft
B has the larger range.
Explanation:
To find the range, find the difference between the minimum and maximum depths for each submarine. Remember that your answer will be positive.
Sub A:
-146ft - (-532ft) = 386 ft
Sub B:
-194ft - (-621ft) = 427 ft
Submarine B has a larger range.
