Let the first even number be 2x
Let the next even number be 2x + 21/5 *(2x) + 2/3 (2x + 2) = 882/5 *x + 4/3 (x) + 4/3 = 88
Multiply by 15 to get rid of the fractions.2*3 x + 20x + 20 = 88 * 156 x + 20x + 20 = 1320 26x + 20 = 132026x = 1300x = 1300/26x = 502x = 1002x + 2 = 1021/5 * 100 = 202/3 * 102 = 34*2 = 6820 + 68 = 88

The sign of acceleration is positive.
Step-by-step explanation:
Consider the provided information.
It is given that A student drops a penny from the top of a tower and decides that she will establish a coordinate system in which the direction of the penny's motion is positive.
Here the direction of the velocity is positive, and the velocity is increasing.
Acceleration is defined as the rate at which an object changes its velocity.
Since velocity is positive therefore the acceleration is also positive.
Hence, the sign of acceleration is positive.

Answer:
4/5
Step-by-step explanation:
Because if it can eat 2/5's in 1/2 hours, then if it eats for 1 whole hour or 2/2's it will be able to eat 4/5's of it's own body weight.
Just imagine that one half hour is 1 and if you add two half hours together it makes one complete hour or 2/2. So just multiply it by 2 cause it was eating for two half hours.
