Answer:

x = -36

Step-by-step explanation:

5 + $\frac{x}{6}$ = -1

$\frac{x}{6}$ = -1 - 5

$\frac{x}{6}$ = -6

x = -6 * 6

x = -36

Answer:

x = -36

Step-by-step explanation:

5 + x/6 = - 1

x/6 = - 1 - 5

x/6 = - 6

x = - 6 / 1/6

x = - 6 * 6/1

x = - 36

John bought 3 pencils for $0.75 each and a notebook for $4.25. If the tax rate is 5%, what is the total amount of John's purchas

SIZIF [17.4K]

Answer:

$6.83

Step-by-step explanation:

First calculate the before-tax total amount:

$0.75 + $0.75 + $0.75 + $4.25, or

3($0.75) + $4.25 = $2.25 + $4.25 = $6.50 (total before tax)

The before-tax total PLUS the 5% tax comes to:

$6.50 + 0.05($6.50) = $6.50 + $0.33 = $6.83

Two Families went to Rollercoaster World. The Brown Family paid $170 for 3 children and 2 adults. The Peckham Family paid $360 f

Lisa [10]

Answer:

The system of equations are;

3x + 2y = 170

4x +6y = 360

Step-by-step explanation:

Form simultaneous equations and solve

Let x=price of children tickets

Let y=price of adult tickets

The Brown Family paid $170 for 3 children and 2 adults , this forms the equation as:

3x + 2y =$ 170

3x + 2y = 170 --------------------------equation (i)

The Peckham Family paid $360 for 4 children and 6 adults.

4x + 6y = $360

4x +6y = 360 ---------------------------equation (ii)

Solving the equations by graph will give value of x=30 and y=40

The price of children tickets was $30 and that of adults was $40

What are the solutions of x^2 = -7x-8

Vilka [71]

$Solution, solve\:for\:x,\:x^2=-7x-8\quad :\quad x=\frac{-7+\sqrt{17}}{2},\:x=\frac{-7-\sqrt{17}}{2}$

$Steps:$

$x^2=-7x-8$

$\mathrm{Add\:}8\mathrm{\:to\:both\:sides},\\x^2+8=-7x-8+8$

$\mathrm{Simplify},\\x^2+8=-7x$

$\mathrm{Add\:}7x\mathrm{\:to\:both\:sides},\\x^2+8+7x=-7x+7x$

$\mathrm{Simplify},\\x^2+7x+8=0$

$Solve\:with\:the\:quadratic\:formula,\\\mathrm{For\:}\quad a=1,\:b=7,\:c=8:\quad x_{1,\:2}=\frac{-7\pm \sqrt{7^2-4\cdot \:1\cdot \:8}}{2\cdot \:1},\\x=\frac{-7+\sqrt{7^2-4\cdot \:1\cdot \:8}}{2\cdot \:1}:\quad \frac{-7+\sqrt{17}}{2},\\x=\frac{-7-\sqrt{7^2-4\cdot \:1\cdot \:8}}{2\cdot \:1}:\quad \frac{-7-\sqrt{17}}{2}$

$\mathrm{The\:final\:solutions\:to\:the\:quadratic\:equation\:are:},\\x=\frac{-7+\sqrt{17}}{2},\:x=\frac{-7-\sqrt{17}}{2}$

$\mathrm{Hope\:This\:Helps!!!}$
