Answers

Answer 1

Answer: The answer for the question in this problem would be $12 is the price of candy bars.This is computed by establishing the equation based on the statement, x +y = 20 and 3x + 5y = 76. Follows:

3 (20 - y) +5y = 76
60 - 3y + 5y = 76
2y = 16
y = 8

x = 20 -y
x = 20 - 8
x = 12

Answer 2

Answer:

Answer:

A: 12

Step-by-step explanation:

The answer for the question in this problem would be $12 is the price of candy bars.This is computed by establishing the equation based on the statement, x +y = 20 and 3x + 5y = 76. Follows:

To my knowledge, the answer should be there is no difference since I found the sum, however the answer is something else, could someone please explain

Answers

In the first series, the summation applies to the whole (2n+3) inside
the parentheses, so the 3 gets summed up 5 times.

But in the second one, the summation only applies to the 2n , so
the 3 is only added after the summation is finished.

The difference between five 3s the first time and one 3 the second time
is your 12 .

The difference between them is 12 because :
the sum of first series is : 2 * ( 1 + 2 + 3 + 4 + 5 ) + 15;
the sum of the second series is : 2 * ( 1 + 2 + 3 + 4 + 5 ) + 3.

Where is the genetic information found in eukaryotic cells?lysosomes

nucleus

mitochondria

ribosomes

Answers

The answer is nucleus.

Explanation:

The nucleus is like the brain of the cell, where genetic information is located and stored. It can’t be the mitochondria because that’s where ATP (energy) is generated. It can’t be the ribosomes because that is the area of informational decoding. It can’t be the lysosomes because that is the area of virus destruction.

There are multiple chickens and rabbits in a cage. There are 72 heads and 200 feet inside the cage. How many chickens and how many rabbits?

Answers

Given:
heads = 72
feet = 200
Chicken = c
Rabbit = r

c + r = 72
2c + 4r = 200

c = 72 - r

2c + 4r = 200
2(72-r) + 4r = 200
144 - 2r + 4r = 200
2r = 200 - 144
2r = 56
r = 56/2
r = 28

c = 72 - r
c = 72 - 28
c = 44

There are 44 chicken and 28 rabbits.
