Answer:
11/6=x
Step-by-step explanation:
System of Linear Equations entered :
[1] y=5x-7
[2] -3x-3y=-12
Equations Simplified or Rearranged :
[1] y - 5x = -7
[2] -3y - 3x = -12
Graphic Representation of the Equations :
-5x + y = -7 -3x - 3y = -12
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 5x - 7
// Plug this in for variable y in equation [2]
[2] -3•(5x-7) - 3x = -12
[2] - 18x = -33
// Solve equation [2] for the variable x
[2] 18x = 33
[2] x = 11/6
// By now we know this much :
y = 5x-7
x = 11/6
// Use the x value to solve for y
y = 5(11/6)-7 = 13/6
Solution :
{y,x} = {13/6,11/6}

The department store buys a suit for $72. They mark it up 110%, what is the
mark-up amount?
Answer:
$79.20
Step-by-step explanation:
to find markup just multiply 72 by 110%. Conver 110% to a decimal, which is 1.1 Then multiply 72 by 1.1 = 79.2
So the markup amount is $79.20

Naomi and Hudson work at a dry cleaners ironing shirts. Naomi can iron 35 shirts per hour, and Hudson can iron 20 shirts per hour. Naomi and Hudson worked a combined 13 hours and ironed 395 shirts. Write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked. Define the variables that you use to write the system.
Answer:
Given that Naomi and Hudson work at a dry cleaners ironing shirts, and Naomi can iron 35 shirts per hour, while Hudson can iron 20 shirts per hour, knowing that Naomi and Hudson worked a combined 13 hours and ironed 395 shirts, to write a system of equations that could be used to determine the number of hours Naomi worked and the number of hours Hudson worked, the following logical reasoning should be performed:
Naomi, working 13 hours, can iron up to 455 shirts (13 x 35), with which, every hour that Hudson has worked and she does not imply a decrease of 15 ironed shirts. Since 455 - 395 equals 60, and 60/20 equals 3, it is determined that Hudson worked 3 hours, while Naomi worked 10 hours.
Thus, the proposed inequality would be the following:
35Y + 20X = 395

Complete Question:
The deck that Amos is building is in the shape of a parallelogram, DGRY. The measure of D is five-halves the measure of Y. Find the measure of each angle of the deck.
Answer:
[tex]\angle G = \angle Y = 51.43 ^{\circ}[/tex]
[tex]\angle D = \angle R = 128.57 ^{\circ}[/tex]
Step-by-step explanation:
Given
Shape: Parallelogram DGRY
Dimension: [tex]\angle D = \frac{5}{2}\angle Y[/tex]
Required
Find the measure of each angle
D and R are opposite sides & G and Y are also opposite sides.
So, we have:
[tex]\angle D = \angle R = \frac{5}{2}\angle Y[/tex]
and
[tex]\angle G = \angle Y[/tex]
The sum of angles is given as:
[tex]\angle D + \angle G + \angle R + \angle Y=360^{\circ}[/tex]
Substitute values for [tex]\angle D, \angle G \ \& \angle R[/tex]
[tex]\frac{5}{2}\angle Y + \frac{5}{2}\angle Y + \angle Y + \angle Y = 360^{\circ}[/tex]
Take LCM
[tex]\frac{5\angle Y + 5\angle Y + 2\angle Y+ 2\angle Y}{2}= 360^{\circ}[/tex]
[tex]\frac{14\angle Y}{2}= 360^{\circ}[/tex]
Multiply both sides by [tex]\frac{2}{14}[/tex]
[tex]\frac{2}{14} * \frac{14\angle Y}{2}= 360^{\circ} * \frac{2}{14}[/tex]
[tex]\angle Y= 360^{\circ} * \frac{2}{14}[/tex]
[tex]\angle Y= \frac{ 360^{\circ} *2}{14}[/tex]
[tex]\angle Y= \frac{720^{\circ}}{14}[/tex]
[tex]\angle Y= 51.43 ^{\circ}[/tex]
So:
[tex]\angle G = \angle Y = 51.43 ^{\circ}[/tex]
[tex]\angle D = \frac{5}{2}\angle Y[/tex]
[tex]\angle D = \frac{5}{2} * 51.43^{\circ}[/tex]
[tex]\angle D = \frac{5* 51.43^{\circ}}{2}[/tex]
[tex]\angle D = \frac{257.15^{\circ}}{2}[/tex]
[tex]\angle D = 128.57 ^{\circ}[/tex]
Hence:
[tex]\angle D = \angle R = 128.57 ^{\circ}[/tex]

Which of the following represents the general equation for the geometric sequence?
-1, -2, -4, …
a n = 2 n - 1
a n = -1 · 2 n - 1
a n = 1 · 2 n + 1
a n = 1 · 2 n - 1
Answer:
-1,-2,-4
an = a1 * r^(n - 1)
a1 = first term = -1
r = common ratio = 2
so the equation would be : an = -1 * 2^(n - 1)

From the set {7.8, 8.5, 9.1, 9.9}, use substitution to determine which value of x makes the equation true. 3.2 (x - 6.7) = 5.76
Answer:
8.5
Step-by-step explanation:
Given the equation :
3.2(x - 6.7) = 5.76
x - 6.7 = 5.76 / 3.2
x - 6.7 = 1.8
x = 1.8 + 6.7
x = 8.5
Answer:
8.5

in standard form? in general form?
2.How will you determine the equation of the circle given the center and radius ?
Answer:
Step-by-step explanation:
Circle Standard Form
The standard form of a circle's equation is (x-h)² + (y-k)² = r² where (h,k) is the center and r is the radius. To convert an equation to standard form, you can always complete the square separately in x and y.
