Answer:
2.9
Step-by-step explanation:
You can find this answer two different ways.
First, you can turn the percent into a decimal, multiply the two numbers, and add them together. (0.16 * 2.5) and then (0.4 + 2.5)
Second, you could find the decimal and add it to 1.0 so you get 1.16 and multiply by 2.5. (1.16 * 2.5)
The answer is to put the data from least to greatest. You can’t do anything with the data until you put it from least to greatest. (I am 98% sure that is correct)
A=3B
4.35A+5.40B=780.95
Substitute 3B into A for the second equation:
4.35(3B)+5.40B=780.90
13.05B+5.40B=780.90
18.45B=780.90
B=42.33
Plug into equation 1:
A=3B
A=3(42.33)
A=126.98
Answer:
x = -1, y = 1.5
Step-by-step explanation:
3x + 6y = 6 -----> x + 2y = 2
-3x + 2y = 6 -----> -3x + 2y = 6
------------------
4x = -4
x = -1, y = 1.5
