Let garret’s age be x
x + 2 + (x + 3) + 2 = 39
2x + 7 = 39
2x = 32
x = 32/2
x = 16
Garrett’s age after two years = 16 + 2 = 18
China plate is 12 years (16-4) and Glass plate is 4 years (12÷3)
Answer:
88 Inches
Step-by-step explanation:
For any bicycle tire of a given diameter, the approximate distance moved by the bicycle each time the wheel goes around is determined by the circumference of the circular wheel.
Since the diameter =28 Inches
Circumference =![\pi d =\frac{22}{7}X28 =88$ Inches](https://tex.z-dn.net/?f=%5Cpi%20d%20%3D%5Cfrac%7B22%7D%7B7%7DX28%20%3D88%24%20Inches)
The bicycle moves 88 Inches forward each time the wheel goes around.
Answer:
(1, 2)
Step-by-step explanation:
x2-x1/2, y2-y1/2
Plug in the values, and you should get (1, 2)
Easy peasy
the midpoint between
![(x_1,y_1)](https://tex.z-dn.net/?f=%28x_1%2Cy_1%29)
and
![(x_2,y_2)](https://tex.z-dn.net/?f=%28x_2%2Cy_2%29)
is
![(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})](https://tex.z-dn.net/?f=%28%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D%2C%5Cfrac%7By_1%2By_2%7D%7B2%7D%29)
just average them
so given that (3,5) is the midpoint of (-4,5) and (x,y)
![(\frac{-4+x}{2},\frac{5+y}{2})=(3,5)](https://tex.z-dn.net/?f=%28%5Cfrac%7B-4%2Bx%7D%7B2%7D%2C%5Cfrac%7B5%2By%7D%7B2%7D%29%3D%283%2C5%29)
so by logic
![\frac{-4+x}{2}=3](https://tex.z-dn.net/?f=%5Cfrac%7B-4%2Bx%7D%7B2%7D%3D3)
and
![\frac{5+y}{2}=5](https://tex.z-dn.net/?f=%5Cfrac%7B5%2By%7D%7B2%7D%3D5)
times both sides by 2 for everybody
-4+x=6 and 5+y=10
add 4 to both sides for left one and minus 5 from both sides for right
x=10 and y=5
the coordinate of point C is (10,5)
the x coordinate is 10
