\left \{ {{S=14+L} (I) \atop {S+L=124}(II)} \right.

<span>Substitute (I) into (II), we have:
</span>S+L=124
(14+L)+L=124
14 + 2L = 124
2L = 124 - 14
2L = 110
L =  \frac{110}{2}
\boxed{L = 55}

<span>Replace (II) in (I), we have:
</span>S=14+L
S = 14+ 55
\boxed{S = 69}

Answer:

D. -3x + 18

Step-by-step explanation:

3x - 9y = 18

y = 1/3 x - 2  ... x intercept   0 = 1/3x -2        x=6

perpendicular line slope: - 1/(1/3) = -3 and (6,0) 0n the line

equation: (y-0)/(x-6) = -3

y = -3x +18

Answer:

Compound interest is the best.

Step-by-step explanation:

Simple interest is that which is not added to the initial capital once the term of the investment or credit has expired.

Compound interest is that which is added to the initial capital at the end of the investment or credit.

Simple interest:

I= C x i x t

15,000 * 0.05 * 5 = $ 750

Compound interest:

Cf= Ci (1+i)ᵗ

Cf = 15,000 * (1.039)^5 = $ 18,162.22

So, if Cf - Ci = I -> 3,162.22 is the compound interest.

In 2008 election there was 28 blue states and 22 red states express the red and blue states as fractions in lowest terms of the
Basile [38]
Let's start with the blue states. Out of 50 states, 28 of them were blue.
Therefore, the fraction would be 28/50. Let's reduce it.
28/50=14/25 --> these are the lowest terms for this fraction
Use a calculator to find the decimal solution --> 14/25= .56

Now, let's do the red states. Out of the 50 states, 22 of them were blue.
22/50=11/25 --> lowest terms
Use a calculator --> 11/25= .43
