Answer:
6:2 Simplified: 3;1
Step-by-step explanation:
For every six cups of flour there are 2 cups of milk. Its a 6:2 ratio :)
Answer:
M = -2
Step-by-step explanation:
-17 + 62 = -5 (3M - 3) Distribute -5 into the parentheses and combine like terms
45 = -15M + 15 Subtract 15 from both sides
30 = -15M Divide 15 from both sides
M = -2
Yes, parentheses can change the order in which operations are performed in an expression.
Let us understand this with two examples.
First example.
Let us suppose we have to simplify the expression
In this expression we have evaluated subtraction first instead of multiply.
Second example.
Let us suppose we have to simplify the expression
In this expression we have evaluated multiplication first and then subtraction.
Therefore, from above two examples we can see that parentheses can change the order in which operations are performed in an expression.
Since there is a common difference of one, this is an arithmetic sequence of the form a(n)=a+d(n-1) which in this case is:
a(n)=15+1(n-1)
All arithmetic sequences have a sum which is equal to the average of the first and last terms time the number of terms, mathematically:
s(n)=(2an+dn^2-dn)/2 (that is just the result of ((a+a+d(n-1))(n/2)) )
Since a=15 and d=1 this becomes:
s(n)=(30n+n^2-n)/2
s(n)=(n^2+29n)/2 so
s(10)=(100+290)/2
s(10)=195 logs
Answer:
(x-2)(x^2+2x+4)
Step-by-step explanation:
x^3-8
x^3-2^3, Now using the base equation for the difference of cubes
(x-y) (x+xy+y^2), y is equal to -2 in this instance.
(x-2)(x+2x+4)
