Answer:
1
Step-by-step explanation:
A triangle can only have one right angle.
83/5 would be equivalent to 16 3/4.
Answer:
![5\dfrac{7}{8} c +7](https://tex.z-dn.net/?f=5%5Cdfrac%7B7%7D%7B8%7D%20c%20%2B7)
Step-by-step explanation:
The like terms are the ones containing the variable 'c'. They are combined by adding their coefficients.
Working just with the coefficients of c, we have ...
![2\dfrac{3}{4} +3\dfrac{1}{8}=(2+3)+\left(\dfrac{6}{8}+\dfrac{1}{8}\right)=5\dfrac{7}{8}](https://tex.z-dn.net/?f=2%5Cdfrac%7B3%7D%7B4%7D%20%2B3%5Cdfrac%7B1%7D%7B8%7D%3D%282%2B3%29%2B%5Cleft%28%5Cdfrac%7B6%7D%7B8%7D%2B%5Cdfrac%7B1%7D%7B8%7D%5Cright%29%3D5%5Cdfrac%7B7%7D%7B8%7D)
Then the simplified expression is ...
(2 3/4)c +(3 1/8)c +7
= (5 7/8)c +7
Answer:
91 is a composite number
Step-by-step explanation:
A prime number is the positive number, which has factors 1 and itself.
Example : 1,3,5,7
Clearly 91 is not a prime number, as its factors are:
91 = 1,7,13,91
It has more than 2 factors (1 and itself), hence 91 is a composite number.
Composite number is the number which has factors other than 1 and itself.
