Step-by-step explanation:
10=4+2s
2s=10-4
2s=6
s=6/2
s=3
A squared plus B squared equals C squared
5 x 1,000 = 5,000 a week or 20,000 a month.
take 1,000 divide by 5 and you get 200 a day
$400 on december 31
The answer is the option A, which is: A. x-7=x²+2x-4
The explanation is shown below:
To solve this problem you must apply the proccedure shown below:
1. You have the following system equations given in the problem above:
<span>y=x-7
y=x²+2x-4
2. Therefore, when you substitute for y in the bottom equation, you obtain:
</span>x-7=x²+2x-4
68.5. You take 62 and divide it by the percentage as a decimal, .905. 62 / .905 = 68.5.
