The First One
The Third One
The Forth One
The others result in a lower number than what they are supposed to be. The 3 correct ones end with the exact number of the equations solution number.
Answer:
$56,226
Step-by-step explanation:
x = investment
Earning interest of 3.57% is the equivalent of multiplying the initial balance (investment) by 1.0357;
Over 20 years, the new balance can be found by multiplying the initial balance by (1.0357)²⁰;
We can formulate an equation to solve to get the initial investment:
x(1.0357)²⁰ = 113400
(2.01687752)x = 113400
x = ¹¹³⁴⁰⁰/₍₂.₀₁₆...₎
x = 56225.5263 → 56226

Answer:
x = -5
y = -2
Step-by-step explanation:
<em><u>Since you have y, plug that into the equation:</u></em>
-2x - 7y = 24
-2x - 7(-2) = 24
-2x + 14 = 24
<u><em>Then, subtract 14 from both sides:</em></u>
-2x + 14 = 24
- 14 - 14
__________
-2x = 10
<u><em>Finally, divide both sides by -2:</em></u>
-2x = 10
x = -5
So now you have, x = -5 and y = -2.
