Answer:

3x - 23 = 2828

Step-by-step explanation:

I'll assume the question is supposed to read "The sum of three times a number (x) and −23 is 2828."

"three times a number (x)" can be written as 3x

"sum of three times a number (x) and −23" means 3x - 23

"is 2828"  = 2828

Put them together:

3x - 23 = 2828

==================

<u>Not part of the question</u>

If you want to solve for x:

3x = 2805

x = 935

#14 pls! Help me please y’all
dsp73

Answer: The Answer is 7, Hope this helps! :)

Step-by-step explanation: We know that 6 and 12 are related, 6 times 2 is 12 so if you do the same for 4 and you multiply 4 by 2 you get 8 for the blank side, then subtract 1 from 8 to get 7. Same for the bigger triangle, 6 times 2 is 12 subtracted by 1 is 11.

So final answer is 7 for X!

Which equation represents a circle with the same radius as
sattari [20]

Answer :

(x+1)^2+(y-1)^2=4^2 and (x+1)^2+(y-1)^2=16

Step-by-step explanation:

Given : A circle with the same radius as  the circle shown but with a center at (-1.1).

To find : Which equation represents a circle ?

Solution :

The equation of a circle with center (h,k) and radius r is given by :

(x-h)^2+(y-k)^2=r^2

Here, we are given (h,k)=(-1,1)

and radius r=4 units

So, equation of circle will be :

(x-(-1))^2+(y-1)^2=4^2

(x+1)^2+(y-1)^2=4^2

or (x+1)^2+(y-1)^2=16

Therefore, the required equations of circle are

(x+1)^2+(y-1)^2=4^2 and (x+1)^2+(y-1)^2=16

An equilateral shape is a shape that has all congruent sides.

<em>Sandy has a greater probability of selecting an equilateral shape</em>

Given

Sandy: <em>Equilateral triangle, Rhombus, and Regular hexagon</em>

Robert: <em>Scalene triangle, Kite, Isosceles trapezoid, Non-special quadrilateral, and Obtuse isosceles triangle</em>

All three shapes in Sandy's shape bucket are equilateral.

So, the probability that Sandy picks an equilateral shape is 1

All five shapes in Robert's shape bucket are non-equilateral.

So, the probability that Robert picks an equilateral shape is 0

By comparing the probabilities:

<em>1 is greater than 0</em>

Hence, Sandy is more likely to pick an equilateral shape than Robert.

A rectangle has an area of 69.6m^2.
omeli [17]

Answer: The perimeter of the rectangle is 53.8. One side is 24, and the other is 2.9.

Step-by-step explanation:

First you need to divide 69.6 meters by 2.9. This gives you 24 as the other side of the rectangle(remember that the area of a rectangle is lw). Next you multiply 2.9 x 2. This gives you 5.8, then you multiply 24 by 2. This gives you 48. You add the two values together,and you get the perimeter of the rectangle as 53.8.
