Answer:
55.55%= boys & 44.44% = girl
Step-by-step explanation:
1000/(1000+800)=1000/1800=.5555 or 55.55% are boys
800/(1000+800)=800/1800=.4444 or 44.44% are girls.
Therefore, 55,55% are boys and 44.44% are girls.
Answer:
If 12,000 are put at an account with 2.5% compound interest in 15 years your total would be $17,379.58
I'm going to use the substitution method.
4x + 4y = -16
-8x - 6y = -20
4x + 4y = -16
- 4x - 4x
--------------------------
4y = -4x - 16
------ ------ ------
4 4 4
y = -x - 4
-8x - 6(-x - 4) = -20
-8x + 6x + 24 = -20
-2x + 24 = -20
- 24 - 24
----------------------------
-2x = 44
------- -------
2 2
x = 22
4(22) + 4y = -16
88 + 4y = -16
- 88 - 88
------------------------
4y = -104
------ ---------
4 4
y = -26
The answer is (22, -26).

Explanation:
We want a number between 4 1/5 and 4.25. We will convert 4 1/5 to a decimal first:
Divide 1 by 5: 1/5 = 0.2.
This makes 4 1/5 = 4 + 1/5 = 4 + 0.2 = 4.2.
We want a number between 4.2, which can be written as 4.20, and 4.25. Any number between will do, so the possible answers would be
4.21, 4.22, 4.23, or 4.24.<u />
