Kate sold 12 of her paintings and purchased 7 more. if kate has 21 paintings now, how many paintings did she have to begin with?

1 answer:

7 0

First, let x or any variable represent the number of paintings Kate initially has. After selling 12 of it, her paintings now becomes only x - 12. Then, she purchased 7 more making the number of her paintings become x - 12 + 7 = x - 5. This number tantamount to 21.

x - 5 = 21 ; x = 26

Thus, Kate initially had 26 paintings.

URGENT PLS RESPOND!!!

Elan Coil [88]

Answer:

$\huge\boxed{d=\sqrt{17}}$

Step-by-step explanation:

Simply use the fact that the change in x squared + the change in y squared = the distance squared. (The Pythagorean Theorem)

1^2 + 4^2 = d^2

1 + 16 = d^2

17 = d^2

d = √17

Hope it helps :)

Find the length of arc XW. Round your answer to the nearest hundredth.

Luda [366]

Answer:

15.08 m

Step-by-step explanation:

The angle XZW :

XZW + 108° = 180°

XZW = 180° - 108°

XZW = 72°

Length of an arc = θ / 360 * πd

d = diameter = XV = 24

Length of arc XW = (72/360) * π * 24

Length of arc XW = 15.0796

Length of XW = 15.08 m

Help answer this if ya know!

C) The +10 is because you already have 10 coins, that will not change. The 6x is because with each passing day, the number of coins increase by 6 (x represents days). The equation then turns into y=6x+10

Hope this helps comment for more questions :)

Y is directly proportional to x^2. It is known that y=10 for a particular value of x. Find the value of y when the value of x is

Mandarinka [93]

<span>Y is directly proportional to x^2. It could be represented by the expression:

y </span>α x^2

We can make it into an equality by inserting the proportionality constant, k.

y = kx^2

k would be constant for any value of y with a corresponding value of x. We solve the problem by this concept as follows:

y1/(x1)^2 = y2/(x2)^2
10/(x1)^2 = y2/(x1/2)^2
10/4 = y2

Therefore, when the value of x is halved, y is equal to 10/4.
