Answer:

19.8494332413? Sorry I couldn't be more helpful.

Step-by-step explanation:

Use the Pythagorean theorem.

$a^{2}+b^2=c^2\\13^2+15^2=x^2\\169+225=x^2\\394=x^2\\19.8494332413=x

David will spend at most $39 on gifts. So far, he has spent $22. What are the possible additional amounts he will spend? Use c f

iren2701 [21]

Answer:

$c\leq \$17$

Step-by-step explanation:

Let

c -----> the additional amount (in dollars) David will spend

we know that

The word " at most" in this context means "less than or equal to"

The amount David has spent plus possible additional amounts he will spend must be less than or equal to $39

The inequality that represent this situation is

$22+c\leq 39$

solve for c

subtract 22 both sides

$c\leq 39-22$

$c\leq \$17$

The maximum amount he could spend is $17

Problem page the sum of two numbers is 47 . the larger number is 17 more than the smaller number. what are the numbers?

user100 [1]

Smaller number = X
Larger Number = X + 17

47 = X + (X+17)
47 = 2x + 17
47 - 17 = 2x
30 = 2x
X = 15

A graph displays point A (5, 3, 4) and point B (−4, 2, 6). Calculate the approximate distance each point is from the origin. Rou

SIZIF [17.4K]

Distance from the origin to the points ≈ 0.41.

<h3>What is the distance between two points ( p,q) and (x,y)?</h3>

The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:

D = √[(x-p)² + (y-q)²]

Point A (5, 3, 4) and point B (−4, 2, 6) are located away from the origin (0,0,0), and the points from the origin to this points are expressed as OB - OA where;

Let OB is the distance from the origin to the point B

Let OA is the distance from the origin to the point A

Using the formula for calculating the distance between two points;

OA = √(z2-z1)²+(y2-y1)²+(x2-x1)²

OA = √(4-0)²+(3-0)²+(5-0)²

OA = √(16)+(9)+(25)

OA = √50

OA = 7.071

Similarly;

OB = √(6-0)²+(2-0)²+(-4-0)²

OB = √(6)²+(2)²+(-4)²

OB = √36+4+16

OB = √56

OB = 7.4833

Distance from the origin to the points = 7.4833 - 7.071= 0.4123

Distance from the origin to the points ≈ 0.41

- 7x + 5(2x - 1) = -20

kramer

Answer:

x= -5

Step-by-step explanation:

-7x + 5(2x - 1) = -20

-7x + 10x - 5 = -20

3x -5 = -20

3x = -15

x = -5
