Answer 1

Answer: to find the value of x we need to use the INVERSE OPERATION of addition which is subtraction. Then we will check our work. lets do it:-

x + 19 = 13
x = ?
13 - 19 = x
13 - 19 = -6
x = - 6

CHECK OUR WORK:-

x + 19 = 13
x = -6
-6 + 19 = 13
We were RIGHT!!

So, x = -6

Choose the kind or kinds of symmetry the following figure

Answers

Answer:

i) Line

ii) point

Step-by-step explanation:

Given is a number 3. We have to find the kind or kinds of symmetry

On seeing 3, we find that no vertical line can divide 3 into exactly two symmetrical figures.

But if we draw a horizontal line in the middle of 3, we get two symmetrical figures up and down the line.

Hence i) symmetric about a line

Next is imaging the middle of 3 end point.

At that point we find that the figure is symmetrical on all sides of the point

Hence there is also a point symmetry

Kinds of symmetry are

i) Line

ii) point

marvin has a chain that is 3 5/12 feet long . he uses 2 1/3 feet of the chain , how much chain is left

Answers

In order to calculate left chain, you need to subtract that as follows:
Left chain = 3 5/12 - 2 1/3
L.C. = 41/12 - 7/3
L.C.= 41-28 / 12
L.C. = 13/12

In short, Your Answer would be 13/12 feet or 1 1/12 feet

Hope this helps!

the answer is 1 1/12, to do that. make 1/3 into 4/12 and subtract 5/12 - 2 4/12= 1 1/12, Hope this helps :)
