Answer:

x = 2

Step-by-step explanation:

Given the equation;

3. 5 (1.25x + 0.5) = 10.5

Open the parenthesis

3.5(1.25x) + 3.5(0.5) =10.5

4.375x + 1.75 = 10.5

4.375x + 1.75 -1.75= 10.5-1.75

4.375x = 8.75

Divide both sides by 4.375

4.375x/4.375 = 8.75/4.375

x = 2

Hence the solution to the equation is 2

To make the same totem pole with wood that costs y dollars Ronald would have to spend a total of $35.19. Explain which property
nikitadnepr [17]

Answer:

Part 1) Subtraction Property of Equality

Part 2) This property can be used , because addition and subtraction have inverse relationships

Step-by-step explanation:

we know that

The<u><em> subtraction property of equality</em></u> tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same

so

we have

10.50+y=35.19

Solve for y

Applying Subtraction Property of Equality

subtract 10.50 both sides

10.50+y-10.50=35.19-10.50

y=\$24.69

Remember that this property can be used , because addition and subtraction have inverse relationships.

A region R in the xy-plane is given. Find equations for a transformation T that maps a rectangular region S in the uv-plane onto
ruslelena [56]
X(u, v) = (2(v - c) / (d - c) + 1)cos(pi * (u - a) / (2b - 2a))
y(u, v) = (2(v - c) / (d - c) + 1)sin(pi * (u - a) / (2b - 2a))

As v ranges from c to d, 2(v - c) / (d - c) + 1 will range from 1 to 3, which is the perfect range for the radius. As u ranges from a to b, pi * (u - a) / (2b - 2a) will range from 0 to pi/2, which is the perfect range for the angle. So, this maps the rectangle to R.
