Answer:

x = -2

Step-by-step explanation:

The segments described in the question are equidistant (meaning they are the same length). Therefore, using algebraic techniques, we can set these two equal to each other and solve for x.

4x - 8 = 6x - 4 Combine like terms by subtracting 6x from both sides.

-2x - 8 = -4 Combine like terms by adding 8 to both sides.

-2x = 4 Divide by -2 on both sides of the equation.

x = -2

Find the number, d, if the sum of five times d and five times five is a<br> hundred.

Gelneren [198K]

The value of d from the given expression is 15

<h3>Word problem leading to equation</h3>

From the given statement the sum of five times d and five times five is a

hundred is interpreted as;

5d + 5(5) = 100

5d + 25 = 100

Subtract 25 from both sides

5d = 100 - 25

5d = 75

d =15

Hence the value of d from the given expression is 15

TIMED

Rudik [331]

-x^2 + 4x + 12 = -3x + 24

-> x^2 - 7x + 12 = 0

-> (x-3)(x-4) = 0

-> x= 3 or 4

so y = 15 when x = 3, y = 12 when x = 4

A circle has an area of 40 square inches. Find the radius to 2 decimal places.

Oksanka [162]

The area of a circle is given by

$A=\pi r^2$

We can solve this equation for r: divide both sides by pi:

$r^2=\dfrac{A}{\pi}$

Consider the (positive) square root of both sides:

$r = \sqrt{\dfrac{A}{\pi}}$

So, in your case, we have

$r = \sqrt{\dfrac{40}{\pi}}\approx 3.57$
