Answer:

102 and 109

Step-by-step explanation:

create an equation to solve:

(x-7) + x = 225

2x -7 = 225

<u> +7 +7</u><u> </u><u> </u> add 7 to both sides

<u>2x</u> = <u>218</u>

2 2 divide both sides by 2

x = 109

<u>109 is the first number</u>

then you solve for the other number

x-7= ?

109 - 7 = 102

<u>102 is the 2nd number</u>

Find the sum +5+(-2)
Nana76 [90]

Answer: +3

Step-by-step explanation: The answer is positive 3 because if you look on a number line, you will only move 3 spaces to the right. You could also look as this problem as a subtraction problem. 5-2=3. Tip: While adding positive and negative numbers, look at the bigger number in the problem. In this case it's 5. The five is positive so the answer is positive. If the five were to be negative, the answer would be negative. In adding the larger number dictates whether the sum will be positive or negative.

a norman window has the shape of a rectangle surmounted by a semicircle. if the perimeter of the window is 25 feet, express the
sp2606 [1]

The area of the window is \frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}

The shape of the Norman window is described as a rectangle surmounted by a semicircle.

Let 'x' be the width of the window.

Then this width corresponds to the diameter of the semicircle.

That is, radius of the semicircle = x/2

Now given the perimeter of the whole window = 25 ft

This perimeter is equal to the sum of 3 sides of the rectangle and the perimeter of the semicircle.

Perimeter of the semicircle = \frac{2\pi r}{2} = \frac{\pi x}{2} , where r is the radius of the semicircle.

Now let 'y' be the length of the window.

Then sum of three sides of the window = 2y + x

So 2y + x + \frac{\pi x}{2} = 25

Therefore, y =( 25 - x - \frac{\pi x}{2} ) / 2

Area of the window = Area of the semicircle + Area of the rectangle =

 \frac{\pi x^2}{8} +xy = \frac{\pi x^2}{8} + x( 25 - x - \frac{\pi x}{2} ) / 2\\ = \frac{\pi x^2}{8} + (25x - x^2 - \frac{\pi x^2}{2} ) / 2

 So Area of the window = \frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}

What is the equation of the line in standard form?
belka [17]

Answer:

y = 6x + 4 \\ slop = 6 \\ y - y0 = slop(x - x0) \\ y - ( - 8) = 6 \times (x - 1) \\ y + 8 = 6x - 6 \\ y = 6x - 6 - 8 = 6x - 14
