20s= 140 I don’t know what this means I don’t understand if someone knows this please help me this is 6th grade math

s=7

Step-by-step explanation:

s is a variable. to isolate, or solve for s on its own, divide both sides by 20.

20s/20=140/20

s=7

So basically when you have a number like 20s it means 20 times s.

Now if you want to solve this problem you would need to know the value of s.

Since we don't know the value of s you need to multiply 20 by different numbers until you get 140

20 x 7 = 140.

So the value of s is 7.

Hope this helps!

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
