Answer:

x = 2, and y = -1. Point form: (2, -1)

Step-by-step explanation:

You solve the system of equations, by solving for one variable, and then subsitiute that variable into the other equation.

The value of x = 2

The value of y = -1

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the first equation be = A
Let the second equation be = B

Now , we have two equations

4x + 3y = 5   be equation (1)

2x + 3y = 1    be equation (2)

Now , on simplifying the equations , we get

Subtracting equation (2) from equation (1) , we get

2x = 4

Divide by 2 on both sides , we get

x = 2

Substitute the value of x in equation (1) , we get

4 ( 2 ) + 3y = 5

8 + 3y = 5

Subtract 8 on both sides , we get

3y = -3

Divide by 3 on both sides , we get

y = -1

Therefore , the value of x and y is 2 and -1 respectively

Hence , The value of x = 2

The value of y = -1

Answer:

139 windows

Step-by-step explanation:

you multiply the 25 by 3 because Amy washes 25 windows per 4 hours and 3x4 is 12 so that would be 75 then you multiply the 32 by 2 because 6x2 is 12 so that would be 64 then you add the 64 and 75 which would give you 139 windows for both of them in 12 hours

Answer:

a. 12 feet b. 12 feet 0.5 inches c. 8.33 %

Step-by-step explanation:

a. How far out horizontally on the ground will it protrude from the building?

Since the rise to run ratio is 1:12 and the building is 12 inches off the ground, let x be the horizontal distance the ramp protrudes.

So, by ratios rise/run = 1/12 = 12/x

1/12 = 12/x

x = 12 × 12

x = 144 inches

Since 12 inches = 1 foot, 144 inches = 144 × 1 inch = 144 × 1 foot/12 inches = 12 feet

b. How long should the ramp be?

The length of the ramp, L is gotten from Pythagoras' theorem since the ramp is a right-angled triangle with sides 12 inches and 144 inches respectively.

So, L = √(12² + 144²)

= √[12² + (12² × 12²)]

= 12√(1 + 144)

= 12√145

= 12 × 12.042

= 144.5 inches

Since 12 inches = 1 foot, 144.5 inches = 144 × 1 inch + 0.5 inches = 144 × 1 foot/12 inches + 0.5 inches = 12 feet 0.5 inches

c. What percent grade is the ramp?

The percentage grade of the ramp = rise/run × 100 %

= 12 inches/144 inches × 100 %

= 1/12 × 100 %

= 0.0833 × 100 %

= 8.33 %

To find the area of the shaded region, you first use the equation A = πr²

The radius of the circle is 9 cm. So A = π(9²)

A = 3.14 (81)

A = 254.34 (entire circle)

The entire circle is 360°

and 4.5 of the 80°'s will equal 360°

254.34 ÷ 4.5 = 56.52

ANSWER: 56.52 cm²

Answer:

56.55 cm^2

Step-by-step explanation:

Since a circle is 360 degrees and the piece is 80 degrees, the shaded area is 4.5 of the total area of the circle (9/2). Find the area of the circle:
