If you're looking for the solution to the system of equations, here's how we solve using substitution
We know that y = x - 1, so we can plug that into the first equation giving
2x - 3(x-1) = -1
Now distribute the 3 giving 2x - 3x + 3 = -1. After combining like terms we get -x + 3 = -1. Now subtract 3 from both sides, -x = -4, and multiply both sides by -1 to make x positive. x = 4
Now we can plug that into the second equation to get y
y = x - 1, and we know that x = 4, so y = 4 - 1, y = 3. The solution is (4, 3)

As <ABC=40

3x-1+34-2x=40

x =40-34+1 = 7

In triangle ABD

3x-1 + 90 +3y + 6= 180

3(7) +3y +95 =180

3y= 180-95-21=64

Y =64/3

Deep's property tax is $690.65 and is due April 15. He does not pay until July 6. The county adds a penalty of 7.3% simple int

bazaltina [42]

$\bf \qquad \textit{Simple Interest Earned}\\\\
I = Prt\qquad 
\begin{cases}
I=\textit{interest earned}\\
P=\textit{original amount deposited}\to& \$690.65\\
r=rate\to 7.3\%\to \frac{7.3}{100}\to &0.073\\
t=years\to &\frac{15+31+30+6}{365}
\end{cases}$

the penalty he'll incurred into, since July 6 is after the deadline of April 15, is I = Prt

now "t" is in years, how many days after April 15 to July 6? well, 15 + 31 + 30 +6, to convert to years, divide by 365

John’s bank account increased in value from last year to those year by 8% to $250. If the account increases by the same percenta

inessss [21]

Answer:

$270

Step-by-step explanation:

We are given;

The rate of increase is 8%
The new amount is $250

We need to determine the value in the next year with the same rate of increase;

Therefore;

250% = 100%

New amount = 100 + 8 = 108%

Therefore;

New amount = (250 × 108)÷ 100

= $270

Therefore, the value in the next year is $270
