Answer: 15$

Step-by-step explanation:

Given

Kendra spent one-third of allowance on a book and two-fifth on snack.

If she had four dollar remaining after purchase

Suppose x is the original amount

\therefore x-\dfrac{x}{3}-\dfrac{2x}{5}=4\\\\\Rightarrow \dfrac{15x-5x-6x}{15}=4\\\\\Rightarrow 4x=60\\\Rightarrow x=15

Thus, 15$ was her total allowance.

Lauren has gross pay of $765 and federal tax withholdings of $68. Determine Lauren's net pay if she has the additional items wit
HACTEHA [7]

Gross pay = 765
federal withholding tax = 68

Social security tax = 765 * 6.2% = 47.43
Medicare tax  = 765 * 1.45% = 11.09
State tax (22% of federal tax) = 68 * 22% = 14.96

765 - 68 - 47.43 - 11.09 - 14.96 = 623.52

<span>Lauren's net pay is 623.52 so the answer is D.</span>

A)<br> 2x + y - 12 = 0<br> x + y + 3 = 0
AVprozaik [17]

Answer:

x=15   and   y= -18

Step-by-step explanation:

2x + y - 12 = 0            Equation 1

x + y + 3 = 0                Equation 2

From two given equations, we can find the value of both x and y by finding the value of one variable from any one of the two equations in terms of other variable and putting it to other equation.

Solving equation 1

Finding 'y' in terms of 'x'           2x+y=12\\y=12-2x                 Equation 3

Putting above equation in equation 3 in 2

                                       x + y + 3 = 0

                                      x+12-2x+3=0

                                         x=15

Putting value of 'x' in equation 3 to find the value of 'y'

                                      y=12-2(15)\\y=12-30\\y= -18
