You subtract the 12 and 3 and then add the 3+5 and you get 9x+8
To get 2 to 5, you multiply 2 by 2.5. do the same to 2/3 to get your answer. 2/3 times 2.5 = 2/3 times 5/2 equals 10/6 or 5/3 cups of sugar (1 and 2/3 cups of sugar) i believe
ok Step-by-step explanation:
Given:
The polynomial is:
To find:
The degrees and determine whether it is a monomial, binomial, or trinomial.
Solution:
We have,
The highest power of the variable <em>x</em> in the given polynomial is 4. So, the degree of the polynomial is 4.
Monomial: Polynomial with one term.
Binomial: Polynomial with two terms.
Trinomial: Polynomial with three terms.
In the given polynomial, we have three terms 
. So, the given polynomial is trinomial.
Therefore, the degree of the polynomial is 4 and it is a trinomial.
Answer:
96
Step-by-step explanation:
First we need to know the mean of the Steve's scores on 6 of his tests. Given the six scores as 92, 78, 86, 92, 95, and 91.
Mean = sum of the scores/Total test taken
Mean = 92+78+86+92+95+ 91/6
Mean = 534/6
Mean = 89
If he took the seventh test and the mean score is raised by 1 them the new mean will be expressed as;
New mean = 92+78+86+92+95+ 91+x/7 = 89+1
Where x is the new score. Note that of a new score is added, the total year taken will also change to 7
To get x;
92+78+86+92+95+ 91+x/7 = 89+1
92+78+86+92+95+ 91+x/7 = 90
534+x/7 = 90
Cross multiply
533+x = 90×7
533+x = 630
x = 630-534
x = 96
Hence the score of the seventh test is 96
