From the sizes give,
there are:
3 - 9's
3 - 8's
1 - 7
2 -10's
1-11
the second graph has the right amount of x's for the given shoe sizes
Answer:
x = - 7
Step-by-step explanation:
Given
4(1 - x) + 2x = - 3(x + 1) ← distribute parenthesis on both sides
4 - 4x + 2x = - 3x - 3, that is
4 - 2x = - 3x - 3 ( add 3x to both sides )
4 + x = - 3 ( subtract 4 from both sides )
x = - 7
<h3>Answer: $26.62 </h3>
============================
Work Shown:
P = 20 is the amount deposited
r = 0.10 is the decimal form of the 10% interest rate
n = 1 means we compound 1 time per year (annually)
t = 3 is the number of years
Plug those four values into the compound interest formula below
A = P*(1+r/n)^(n*t)
A = 20*(1+0.1/1)^(1*3)
A = 20*(1+0.1)^(3)
A = 20*(1.1)^(3)
A = 20*1.331
A = 26.62
I provided the biweekly federal tax table for convenience. If this is not the updated federal tax table, then just understand the concept. The same procedure would be applicable.
On the lefthand-most column, you find the row for $840. Then, at the top row, it indicated the exemption. Since Selina has a single exemption, find the column with 1 in it. The intersection of the designated row and columnis Selina's withheld amount. That would be 80. We find the 21% of this.
80*0.21 = $16.8
Thus, Selina's amount of state tax will be $16.8.
