X-4y=-11<=> -5x + 20y = 55
<span> 5x - 7y = -10</span>
=>0*x + 13*y = 45 => y =45/13 => x = 4*(45/13) -11 = 180/13 -11 =>
x = 37/13;
Answer: 1440
Explanation: when you split it into two shapes (I split it where the split is splitting the eight up) you find the volume of them both. Top shape= 4x4x10=80 bottom shape= 8x8x10=640.
640+80= 720
You will then need to multiply by two (or add 720+720) to get the answer 1440
B. 1/3
There are two numbers less than three on a six-sided die.
So all you have to do is simplify the fraction 2/6.
2/6 = 1/3 which is B.
