So, first, you add x to both sides of the equation
Second, you subtract 3 from both sides of the equation
Last, you would multiply both sides of the equation by 2
It would look like this.....
-1/2x+3=-x+7
1/2x+3=7
1/2x=4
2*(1/2)=(2)*4
x=8

-1/2x + 3 = -x + 7

We're simply just trying to get "x" by itself.

So, in order to do this, we must move anything that doesn't have "x" in it to the other side.

SO, subtract 3 from both sides.

-1/2x = -x + 7 - 3

Then, add x to both sides.

-1/2x + x = 7 - 3

Then, simplify.

1/2x = 4

Multiply both sides by 2.

2 · 1/2x = 4 · 2

Simplify.

x = 8

Human body has 209 bones, 2.9% are in the inner ear hw many bones are in the ear?
lubasha [3.4K]
First, we should change this question into an expression.
    -  we convert the percent into decimal
209 × 0.029 = 6.061 (I used a calculator for this)

So there are approximately 6 bones in the inner ears, which is approximately 3 bones in each ear. 

hope this helps

bruce is playing with a set of base-ten blocks. he has 65 ten-blocks and 7 one-blocks. what is the value of his blocks
Oksi-84 [34.3K]
The 65 tens blocks can be solved by doing 65x10 which is 650.  the 7 ones blocks can be solved by 1x7  which is 7 so you then add up 650 and 7 to get a grand total of 657

Sin(x)= 4/5 dilated by 2

It would remain the same (4/5). <span>Sin of the angle is unchanged regardless of the size; it is a ratio related only to the angle, not the size of the triangles.</span>

Can someone help me with this pls
Yuki888 [10]

Answer:

33.8

Step-by-step explanation:

1) Use Phythagoras theorem to get RS ↓

9.1 ^{2}  + 6 ^{2}  = 118.81 \\  \sqrt{118.81 }  = 10.9

2) RS = RQ

therefore, to get the perimeter, you'll have to total up the sides of the triangle ↓

rs + rq +qt +  ts   \\ = 10.9 + 10.9 + 6 + 6  \\ = 33.8

Hope this helps =)
