Answer:

x=1

Step-by-step explanation:

I will solve your system by substitution.

(You can also solve this system by elimination.)

3x−2y=1;2x+2y=4

Step: Solve3x−2y=1for x:

3x−2y+2y=1+2y (Add 2y to both sides)

3x=2y+1

x 3 = 2y+1 3  (Divide both sides by 3)

x= 2 3 y+ 1 3

Step: Substitute  2 3 y+ 1 3 for xin 2x+2y=4:

2x+2y=4

2( 2 3 y+ 1 3 )+2y=4

10 3 y+ 23 =4 (Simplify both sides of the equation)

10 3 y+ 2 3 + −2 3 =4+ −2 3  (Add (-2)/3 to both sides)

10 3 y= 10 3

10 3 y 10 3 = 10 3 10 3  (Divide both sides by 10/3)

Step: Substitute 1 for yin x= 2 3 y+ 1 3 :

x= 2 3 y+1 3

x= 2 3 (1)+ 1 3

x=1 (Simplify both sides of the equation)

That was a lot to type.

What is 0.275 0.20 0.572 and 0.725 greatest to least
Andru [333]
.725 , .572 , .275, .2
You look at the first decimal place to see which is the greatest. 7 is greater than 5 and 2 so it's first. Then 5 is greater than 2 so it is next. For the last two numbers since 2 is the same value you look at the next decimal place. Since 7 is greater than 0 it comes next!

A coin which is tossed straight up into the air. After it is released it moves upward, reaches its highest point and falls back
Helen [10]

Answer:

Answers  G, and A

Step-by-step explanation:

the motion of a body is as a result of the various forces acting on it.

As the coin is tossed upwards an upwards force acts on it and this force decreases up to the highest point the coin reaches. at the highest point the force of gravity applies. This force is downwards and constant (9.8m/s^{2}).

HELP ASAP TEST IS OMOST OVER!!!!!!!!!!
svet-max [94.6K]

Answer: C)46 ft

Step-by-step explanation:

We know that the circumference of a circle can be calculated with this formula:

C=2\pi r

Where "r" is the radius of the circle.

Since John is putting a fence around his garden that is shaped like a half circle and a rectangle, then we can find how much fencing he needs by making this addition:

Fencing=\frac{2\pi r}{2}+2l+w

Where "l" is the lenght of the rectangle and "w" is the width of the rectangle.

Since we know that the radius of the circle is half its diameter, we can find "r". This is:

r=\frac{7ft}{2}=3.5ft

Then, substituting values (and using \pi=\frac{22}{7}), we get:

Fencing=\frac{2(\frac{22}{7})(3.5ft)}{2}+2(14ft)+7ft=46ft
