Answer:
× ![10^{-4}](https://tex.z-dn.net/?f=10%5E%7B-4%7D)
Step-by-step explanation:
To convert to scientific notation, you need the number to be less than 10, but greater than 1 and is multiplied by a base of 10 to the power of the number of times you moved the decimal. So you need to shift the decimal place 4 times to the right to get to 2.077 (which is less than 10, but greater than 1). The next part is that you’ll need a base number, which is 10 because your moving the decimal by 10s. Since the decimal is being moved to the right, the exponent will be negative. You moved it 4 times so it’s
. The finished answer is:
× ![10^{-4}](https://tex.z-dn.net/?f=10%5E%7B-4%7D)

Answer:
$7; Cost of a box of apples (x)
$13; Cost of a box of oranges (y)
Step-by-step explanation:
Matt: 3x + 14y = 203 3(-y + 20) + 14y = 203 3x + 14(13) = 203
Ming: 11x + 11y = 220 -3y + 60 + 14y = 203 3x + 182 = 203
11x = -11 11y = 143 3x = 21
x = -y + 20 y = 13 x = 7
