−5x + y = −2 −3x + 6y = −12 solved by substitution please work so i can understand

Answers

Answer:

x=0 and y= -2

Step-by-step explanation:

−5x+y=−2for y:

−5x+y=−2

−5x+y+5x=−2+5x(Add 5x to both sides)

y=5x−2

5x−2foryin−3x+6y=−12:

−3x+6y=−12

−3x+6(5x−2)=−12

27x−12=−12(Simplify both sides of the equation)

27x−12+12=−12+12(Add 12 to both sides)

27x=0

x=0

Substitute0 for X in y=5x−2:

y=5x−2

y=(5)(0)−2

y=−2(Simplify both sides of the equation)

Make y subject:
y = -2 + 5x
Sub into other equation as y:
-3x + 6(-2 + 5x) = -12
-3x -12 + 30x = -12
27x = 0
x = 0
Sub in X to find Y:
-5(0) + y = -2
y = -2

Jill and Gary share £63 in the ratio 2:5
Work out how much each person gets.

Answers

Answer:

Jill gets €18 Gary gets €45.

Step-by-step explanation:

First you add the two numbers of the ratio together. 2+5=7. Then you divide the constant, 63, by the total of the ratio, 7. 63/7=9. Then you multiply each number of the ratio by the quotient. 2 x 9= 18. 5 x 9= 45.

Answer:

The Area of the given figure is 6 inch²

Step-by-step explanation:

For a given Trapezoid

side a = 1 ½ = 1.5 inch

side b = 2½ = 2.5 inch

height (h) = 3 inch

Now, Area of Trapezoid

Formula:

A = ½ (a + b) × h

A = ½ (1.5 + 2.5) × 3 inch

A = ½ × 4 × 3 inch

A = 2 × 3 inch

A = 6 inch²

Thus, The Area of the given figure is 6 inch²

Streets in the city can be represented by the equations in the given table. Use the equations to find the type of quadrilateral that the streets form. Justify your answer.

Answers

Answer:

It is a rhombus.

Step-by-step explanation:

We have the four equations:

3x - y = -4

3y - x = 4

3y = x + 12

y = 3*x - 4

First, we need to write all of them in slope-intercept form, so they are easier to read.

We get:

y = 3*x+ 4

y = (1/3)*x + 4/3

y = (1/3)*x + 12/3

y = 3*x - 4

First, we can see that:

y = 3*x+ 4 and y = 3*x - 4

are parallel lines, because they have the same slope.

y = (1/3)*x + 4/3 and y = (1/3)*x + 12/3 also are parallel lines, because they have the same slope.

Then this is a parallelogram.

Now, here we have two slopes, 3 and 1/3.

Remember that for a line y = a*x + b

A perpendicular line would be written as:

y = -(1/a)*x + c

From this we can see that there are no perpendicular lines in our set of lines.

Then this can not be a square nor a rectangle.

It can not be a trapezoid, because we would need 3 different slopes to make a trapezoid, and here we have only two.

Then this can only be a rhombus.

Below you can see the graph of the four lines to see which quadrilateral they form.

The base sales tax rate in Florida is 6%,
The total cost of purchasing a leotard, including tax,
was $19.61. Find the cost of the leotard before sales
tax.

Answers

Answer:

$18.43

Step-by-step explanation:

19.61 decrease 6% =

19.61 × (1 - 6%) = 19.61 × (1 - 0.06) = 18.4334

The cost of the leotard before sales tax is $18.5

What is the formula to calculate sale tax ?

The sales tax is calculated by multiplying the total sales or selling price by the rate of sales tax.

Amount of sales tax = rate of sales tax × Total sales

Rate of sales tax = percent of sales tax / 100

Let the cost of leotard before tax be x

Given that sales tax of 6% is applied over x

The the amount of sales tax =( 6/100) ×x = 3x / 50

The total cost after applying sales = x + (3x/50) = 53x/50

Given that the total cost of purchasing a leotard including tax = $19.61

⇒ 53x/50 = 19.61

⇒53x = 19.61×50

⇒ x = 980.5/53 = 18.5

Therefore, the cost of the leotard before sales tax is $18.5
