Its a. An enlargment on a scale of 3/1.
B.) 10 The length of the board is 7×12 = 84
the largest number of 15 inch pieces that
jeremy can cut is 5. 84÷15 is a quotient of
5 with a remainder of 9. 5×5=10
Answer:
x=41
y=139
Step-by-step explanation:
x+y = 180 since they form a straight line
y is 3x +16
y = 3x +16
Replace y in the first equation
x+3x +16 = 180
Combine like terms
4x +16 = 180
Subtract 16 from each side
4x+16-16 =180-16
4x =164
Divide each side by 4
4x/4 =164/4
x = 41
y = 3x +16
y = 3*41 +16 = 123+16 =139
To answer this, you use the formula 
where
is the simple interest that builds
is the principal (AKA the amount invested/borrowed)
is the interest rate per year
is the lenght of the loan, in years.
In your situation:
![\begin{aligned}I &= (\$3000)(5 \%/\text{year})(3 \text{ years})\\[0.5em]&= (3000)(0.05)(3)\\[0.5em]&= 450\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7DI%20%26%3D%20%28%5C%243000%29%285%20%5C%25%2F%5Ctext%7Byear%7D%29%283%20%5Ctext%7B%20years%7D%29%5C%5C%5B0.5em%5D%26%3D%20%283000%29%280.05%29%283%29%5C%5C%5B0.5em%5D%26%3D%20450%5Cend%7Baligned%7D)
This means there'd be $450 of simple interest due at the end of 3 years.
