Answer:
Joseph caught 7 tadpoles
Step-by-step explanation:
Let the number of tadpoles caught by Joseph be x
The number of tadpoles Wendy caught will be ;
9(x + 3)
After Joseph was upset, he released half of Wendy’s tadpole and then six times as many as Joseph caught swam away leaving Wendy with only three tadpoles left;
Hence, mathematically;
9(x + 3)/2 - 6x = 3
Multiply through be 2
9(x + 3) - 12x = 6
9x + 27 -12x = 6
9x -12x = 6-27
3x = 21
x = 21/3
x = 7

Answer:
( x - 2 )^2 + ( y - 1 )^2 = 1
Step-by-step explanation:
As i previously explained,
The general form of equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2.
h and k are the co-ordinates of the center of circle and r is the radius
Here, We have (2,1) as the co-ordinates of the center of circle
Now,
( x - h )^2 + ( y - k )^2 = r^2
or,( x - 2 )^2 + ( y - 1 )^2 = r^2
The radius of the circle is 1 units(from figure)
So, put that in, we get
( x - 2 )^2 + ( y - 1 )^2 = 1^2
or, ( x - 2 )^2 + ( y - 1 )^2 = 1
You can simplify this or leave it here.
Answer:she had 11 video games on Monday.
Step-by-step explanation:
Let x represent the number of video games that Susie had initially.
On Tuesday, Susie buys three new video games from the store. This means that the total number of video games that Susie had would be x + 3
On Wednesday, she sells half of her video games in order to make extra money. This means that the number of video games that she sold is
(x + 3)/2. The number of video games left would be
x - (x + 3)/2
If she has 4 video games left after selling, it means that
x - (x + 3)/2 = 4
2x - (x + 3) = 8
2x - x - 3 = 8
x - 3 = 8
x = 8 + 3 = 11
