Answer:

v = 3

w = -3

I used a calculator called m.a.t.h.w.a.y :)

24y - 22 = 4 ( 6y - 6 )
Pie
I don’t think their is a solution to this equation
because if you expand the second half it is= 24y-24 which would make the equation
- 24y-22=24y-24
and because the number next to the y is the same on both sides, no matter what y is if we subtract different numbers from each side we will never get the same value for each side of the =

Claire Drew model of 5/10 explain how Claire could change her model to show how many hundreds are in 5/10 I know this is like my
natta225 [31]

Answer:

There are 0.005 hundreds in 5/10.

Step-by-step explanation:

Claire drew model of 5/10

We want to know how many hundreds are in 5/10.

Let us use an obvious example.

There are three 2's in 6 right?

Suppose we didn't know this, and we are told to find how many 2's are in 6, we get this by representing this in an algebraic expression as:

There are x 2's in 6. This can be written as

2x = 6

Solving for x, by dividing both sides by 2, we have the number of 2's that are in 6.

x = 6/2 = 3.

Now, to our work

We want to find how many hundreds are in 5/10. We solve the equation

100x = 5/10

x = 5/1000 = 0.005

There are 0.005 hundreds in 5/10.

What is the area of the shaded region plzz help
Aneli [31]

Answer:

78.10 cm^2

Step-by-step explanation:

The area of the shaded region is the area of the rectangle subtracted from the area of the circle.

area of circle = (pi)r^2

area of rectangle = LW

shaded area = area of circle - area of rectangle

shaded area = (pi)r^2 - LW

shaded area = (pi)r^2 - LW

shaded area = (3.14159)(6 cm)^2 - (7 cm)(5 cm)

shaded area = (3.14159)(36 cm^) - 35 cm^2

shaded area = 113.097 cm^2  35 cm^2

shaded area = 78.097 cm^2

Answer: 78.10 cm^2
