Answer:

The length of side x is x = \sqrt{6}

Step-by-step explanation:

Pythagorean Theorem:

In a right triangle, with sides a and b, and hypothenuse h, we have that:

a^2 + b^2 = h^2

In this question:

The vertical line on the sides means that both are equal, that is, measuring x, so a = b = x.

Hypothenuse is the square root of 12. So h = \sqrt{12}

x^2 + x^2 = (\sqrt{12})^2

2x^2 = 12

x^2 = \frac{12}{2}

x^2 = 6

x = \sqrt{6}

The length of side x is x = \sqrt{6}

You have a part-time job that pays $4.75/hr with tips averaging $4.50/hr. Your deductions are FICA (7.65%), federal tax withhold
Nataly_w [17]

Answer:

$95.05

Step-by-step explanation:

The job pays 4.75 per hour and he also collects tips averaging 4.50 per hour.

This means that in 20 hours he will have up to__ since he works 20 hours per week

(4.75 + 4.50) × 20

= $185

FICA deductions = 7.65/100 x 185

= $14.1525

FTW = 12.5/100 × 185

= $23.125

STW = 6.85/100 × 185

= $12.6725

Total amount of all 3 deductions

= $49.95

And remember that he also has to save $40 per week

The discretionary income left with him be

185 -(49.95 + 40)

185 - 89.95

= $95.05

What is the elimination to this solution i think its b
Blababa [14]

EXPLANATION:

To get the solution of the simultaneous equation, using the elimination method:

We will have the following steps:

Step 1:

Write the two equations:

\begin{gathered} y=-\frac{1}{2}x+3 \\ y=-\frac{7}{2}x-3 \end{gathered}

Step2: Subtract the two equations:

\begin{gathered} y-y=-\frac{1}{2}x-(-\frac{7}{2}x)+3-(-3) \\ 0=-\frac{1}{2}x+\frac{7}{2}x+6 \\  \end{gathered}

Step 3: Simplify the expression

\begin{gathered} 0=3x+6 \\ 3x=-6 \\ x=-\frac{6}{3} \\ x=-2 \end{gathered}

Step 4: Substitute x=-2 into the formula:

\begin{gathered} y=-\frac{1}{2}x+3 \\ y=-\frac{1}{2}\times-2+3 \\ y=1+3 \\ y=4 \end{gathered}

Therefore, the answer is

(-2,4)

Thus,

Option B is correct
