Answer:
x=5
Step-by-step explanation:
We know that a pentagon is in total 540 degrees. From this, we add all other numbers and set them equal to 540 to solve for x.
So, after adding all the angles and setting them equal to 540, we get this.
21x+435=540
21x=105
x= 5
If you want, plug 5 into x and see if it adds up to 540 to check
21(5)+435=540
Answer:
No
Step-by-step explanation:
Proportional is when there is a pattern in a graph/table
X=tax
240+x
that would be your answer i believe
Answer:
Two consecutive numbers whose squares differ by 33 are 16 and 17
Step-by-step explanation:
lets assume first number be x
since numbers are consecutive , so other number will be x + 1
From given information in question
(x + 1)² - x² = 33
⇒ (x² + 1² + 2x) - x² = 33 [ since (a+b)² = a² + b² + 2ab ]
⇒ x² + 1² + 2x - x² = 33
⇒ 2x + 1 = 33
⇒ 2x = 33 - 1
⇒ x = 32/2 = 16
so one number is x = 16 and other number is x + 1 = 16 + 1 = 17
lets recheck our solution
17² - 16² = 289 - 256 = 33 , And since difference is 33 , two required consecutive numbers are 16 and 17.
Answer:
B- 3,500.
Step-by-step explanation:
This is because 3,500 is the lowest number that can be rounded to 4,000.
3,999 and 4,001 can also be rounded but.. (let me show you an image to help).
3,500 < 3,999 < 4,001.
That goes from smallest to largest numbers that round to 4,000.
Hope that helps. x
