Answer: The value of x must be 7 units.

Step-by-step explanation:

Since we have given that

ABCD is a parallelogram.

Suppose that AC and BD intersect at o.

So, AO = OC.

And we have given that

AO = 5x

OC = 6x-7

According to question,

5x=6x-7\\\\5x-6x=-7\\\\-x=-7\\\\x=7

Hence, the value of x must be 7 units.

A book sold 31,100 copies in its first month of release. Suppose this represents 7.8% of the number of copies sold to date. How
zvonat [6]
For this problem you can create a proportion.
Since 31,100 copies is 7.8% of the total copies spoke up to date you can make this proportion:
31,100. 7.8%
——— =. ———
x. 100%
Now you cross multiply and you will get
7.8x=3,110,000
After this you solve for x by isolating the variable.
7.8x/7.8. 3,110,000/7.8
x=398,717.949
Since the question asks you to round to the nearest whole number which is 7 then the final answer would be 398,718
Answer: There has been 398,718 copies sold to date.

Answer: 0.25 feet


Step-by-step explanation:

Given: Jonathon has paper strips that are all equal in length.

Let x be the length of each paper strip.

Since John lines them up end to end, the length of the line of paper strips= 3 feet

Also total strips used= 12

Therefore, length of line of strips=12x=3\ feet

\\\Rightarrow\ x=\frac{1}{4}\ feet\\\Rightarrow\ x= 0.25\ feet

hence, if Jonathan is correct then the length of each strip will be 0.25 feet.
