Answer:
I assume c In the question is x
-3x + 7 = 1
-3x = - 6
3x = 6
X = 2
Thank you and please rate me as brainliest as it will help me to level up
The answer is in the question. The question says he used 2/3 of it to make sandwiches. Unless your asking what 2/3 of 7/8 is then the answer would be 7/12.
you just multiply the top numbers together and the bottom numbers together and then reduce.
One revolution corresponds to an angular displacement of
, so its angular speed is
![32\,\mathrm{rpm}=\left(32\dfrac{\rm rev}{\rm min}\right)\left(2\pi\dfrac{\rm rad}{\rm rev}\right)=64\pi\dfrac{\rm rad}{\rm min}](https://tex.z-dn.net/?f=32%5C%2C%5Cmathrm%7Brpm%7D%3D%5Cleft%2832%5Cdfrac%7B%5Crm%20rev%7D%7B%5Crm%20min%7D%5Cright%29%5Cleft%282%5Cpi%5Cdfrac%7B%5Crm%20rad%7D%7B%5Crm%20rev%7D%5Cright%29%3D64%5Cpi%5Cdfrac%7B%5Crm%20rad%7D%7B%5Crm%20min%7D)
radians is equivalent to 180 degrees, so the angular speed could also be
![\left(64\pi\dfrac{\rm rad}{\rm min}\right)\left(\dfrac{180}\pi\dfrac{\rm deg}{\rm rad}\right)=11,520\dfrac{\rm deg}{\rm min}](https://tex.z-dn.net/?f=%5Cleft%2864%5Cpi%5Cdfrac%7B%5Crm%20rad%7D%7B%5Crm%20min%7D%5Cright%29%5Cleft%28%5Cdfrac%7B180%7D%5Cpi%5Cdfrac%7B%5Crm%20deg%7D%7B%5Crm%20rad%7D%5Cright%29%3D11%2C520%5Cdfrac%7B%5Crm%20deg%7D%7B%5Crm%20min%7D)
The linear speed depends on the wheel's radius. Suppose its radius is
. Then the wheel has circumference
units. A point on the edge of the wheel travels this distance in one revolution, so its linear speed is
![\left(32\dfrac{\rm rev}{\rm min}\right)\left(2\pi r\dfrac{\rm u}{\rm rev}\right)=64\pi r\dfrac{\rm u}{\rm min}](https://tex.z-dn.net/?f=%5Cleft%2832%5Cdfrac%7B%5Crm%20rev%7D%7B%5Crm%20min%7D%5Cright%29%5Cleft%282%5Cpi%20r%5Cdfrac%7B%5Crm%20u%7D%7B%5Crm%20rev%7D%5Cright%29%3D64%5Cpi%20r%5Cdfrac%7B%5Crm%20u%7D%7B%5Crm%20min%7D)
(where
stands for units of length)
Answer: Ok So Compute successive differences of the terms. If they are all the same, the sequence is arithmetic and the common difference is the difference you have found. If successive pairs of differences have the same ratio, the sequence is geometric The common pattern in an arithmetic sequence is that the same number is added or subtracted to each number to produce the next number. This is called the common difference. The common pattern in a geometric sequence is that the same number is multiplied or divided to each number to produce the next number.and the common ratio is the ratio you have determined.
Hope this helps have a awesome day❤️
Step-by-step explanation:
W is equal to 7
When finding perimeter to add all the sides up so you’ll add 9+17 = 26 and if the perimeter is 40 you’ll subtract that by 26 and you’ll get 14. If there’s 2 sides and we know w is 14 we will divide by 2
